Press Release- New Pest Alert: Highly invasive red-vented bulbul spotted on Maui

Posted on December 8, 2021 by Serena Fukushima

Kahului, Maui- Recent sightings of red-vented bulbuls (Pycnonotus cafer) on Maui have agriculture and wildlife officials concerned. Native to Pakistan and India, red-vented bulbuls are among the International Union for Conservation of Natureʻs (IUCN) Top 100 Invasive Species worldwide. They have long been established on Oʻahu, but have remained absent on all other Hawaiian islands. Over the years, several individuals have been observed on Maui, however, these individuals were removed, and no established breeding population is known on the island. Red-vented bulbuls are on the State of Hawaiʻi Injurious Species list, making it illegal to release or transport them to other parts of the State or export them without a permit. They are a high priority invasive pest for the State of Hawaiʻi.

Long established on Oʻahu, red-vented bulbul’s have remained absent on all other Hawaiian islands. One of the top 100 invasive species in the world, red-vented bulbuls can cause significant damage to our native ecosystems, watershed, and agriculture and orchid industries.

On November 28, 2021, Chris Warren, Forest Bird Program Coordinator at Haleakalā National Park, observed a male red-vented bulbul on Stable Road in Spreckelsville, Maui. Since then, several other sightings have been reported near Costco, Whole Foods, and Queen Kaʻahumanu Center. It is unknown if there are multiple birds or just one individual traveling throughout this area. Two reports were also submitted on December 2 of sightings near Honolua and Kapalua Golf Course in West Maui. These sightings have not yet been verified as red-vented bulbuls.

Red-vented bulbuls are a serious agricultural and wildland pest in Hawaii, and have caused significant damage on Oʻahu. They plague fruit farmers and nurseries, flocking in large groups and devouring commercial fruits such as papaya, mango, lychee, and bananas. They also have a taste for orchid buds, and reportedly caused over $300,000 in damage to the Oʻahu orchid industry one year. Bulbuls are also particularly good at dispersing high-priority plant pests targeted by invasive species committees such as ivy gourd and miconia. If red-vented bulbuls become established on Maui, they pose a severe threat to native forest ecosystems and Mauiʻs watersheds.

Red-vented bulbul are loud with a distinct call. Click on the play button above to listen to one. If you see or hear a red-vented bulbul on Maui, report it immediately to 643pest.org or call (808) 643-PEST.

The red-vented bulbul is about 8 ½ inches long and looks like a black cardinal. Adults are dark with a pointed crest on their head, white abdomen and rump, and crimson under the tail. They also have a slight white marking at the tip of their tail. They make frequent loud calls. The immature bird is like the adult but with some brownish edging on the feathers. Bulbuls are often seen scavenging in parks, hunting for insects in the evening hours, sitting on telephone wires, and are one of the few birds that tend to land on the sides of trees.

Red-vented bulbul’s have a similar body shape to the already established red-crested and northern cardinals. Keep an eye out for dark brown-black coloring, a pointed crest on their head, white abdomen and rump, and crimson under the tail. They also have distinct and loud calls, which are easy to find and listen to on the internet. If you think youʻve spotted a red-vented bulbul, report it immediately to 643pest.org or call 643-PEST (7378). Clear descriptions of the bird, time and place observed, and photos and videos are helpful when submitting reports.

It is crucial to prevent this species from becoming established on Maui. Residents are urged to help by immediately reporting any red-vented bulbul sightings to 643pest.org or calling 643-PEST (7378). Clear descriptions of the bird, time and place observed, and photos and videos are helpful when submitting reports.

Duane Sparkman Receives 2021 Mālama i ka ʻĀina Award

Posted on November 2, 2021 by Serena Fukushima

Duane Sparkman, Chief Engineer at the Westin Maui Resort and Spa, is the 2021 recipient of the Mālama i ka ʻĀina Award. The award is given each year to recognize the efforts in the landscape and agricultural community towards stopping the spread of invasive species in Maui County. The award is presented by the Maui Invasive Species Committee, the Maui Association of Landscape Professionals, and the County of Maui.

With his roots in landscaping, Sparkman worked his way up to become part-owner of a large landscape company that maintained 65 acres of resorts along Maui’s coastlines before coming on board with the Maui Westin Resort and Spa. Along with his day job, Sparkman has pursued his passion of learning about Maui’s unique environment. He has volunteered with over a dozen conservation organizations, removing invasive species and planting endangered plants in some of Maui’s most pristine places. In 2012, he worked at Haleakalā National Park with their resource management team, which drastically changed his view of landscape maintenance. Through his experience, Sparkman came to a realization: “If I don’t have to fertilize a native forest, why do I need to fertilize urban landscapes?” He then proceeded to transform the landscape practices at the Maui Westin Resort and Spa’s 12-acre oceanfront resort to organic practices.

Additionally, Sparkman sits on the board of directors of Maui Cultural Lands as their botanist and is the project manager for a 72-acre Hawaiian cultural reserve called Kīpuka Olowalu. He also has a consulting company called Edaphic Perspective, where he assists homeowners, landowners and municipalities transition to organic landscape practices, and has recently partnered with the Maui Nui Marine Resource Council to assist them with their organic land management division

Sparkman’s nomination stems from his passion in seeing thriving and healthy ecosystems from mauka to makai. He has affected not only the industry he works in, but countless other organizations throughout Maui, by sharing his knowledge and skills with community members, respecting and promoting Hawaiian culture and practices, working with local non-profit organizations, and continuing to improve sustainable landscape practices within Hawaii’s resort industry.

FOR IMMEDIATE RELEASE

Rose-ringed parakeets (RRP) have recently been confirmed on Maui. An interagency effort between the Maui Invasive Species Committee, Hawaii Department of Agriculture, Department of Land and Natural Resources Division of Forestry and Wildlife, Maui Nui Seabird Recovery Project, and Maui Forest Bird Recovery Project has led to one bird being captured in Kihei as a result of an online report to www.643PEST.org, a reporting resource made available by the Hawaii Invasive Species Council. At least four more birds remain at large in West Maui. These four birds were reported by a Napili resident who observed them frequenting a bird feeder. Follow-up visits by staff from the Maui Forest Bird Recovery Project confirmed their presence. Efforts were made to capture these remaining birds on July 30; however, the birds were not observed and are assumed to have moved on to another feeding location.

Rose-ringed parakeets were recently observed at a bird feeder in Napili. These invasive species are not established on Maui and can cause harm to the agriculture industry, native ecosystem, and public health. Report RRP sightings to www.643pest.org or call (808) 643-PEST. Photo: Maui Forest Bird Recovery Project.

Not to be confused with the Rosy-faced Lovebird, which is already established on Maui, Rose-ringed parakeets are native to equatorial Africa and Asia and have invasive populations in over 35 countries. There are established populations of RRP on Oʻahu, Hawaiʻi Island, and Kauaʻi. They are an agricultural pest that causes extensive damage to food crops, especially fruits and grains. On Kauaʻi, they have already successfully invaded farmland and have caused significant losses to harvests. Their high-density roosts, loud calls, and mass accumulation of droppings cause disturbance to humans and are a potential public health risk. If they reach native forests, their impact on native ecosystems could be substantial. The most recent population estimate of Kauaʻi RRP numbers is over 10,000 individual birds, with the rate of expansion steadily climbing along with costs to control them. The Kauai Invasive Species Committee, in partnership with the Rose-ringed Parakeet Working Group, is conducting research to develop management methods to mitigate these harmful pests.

Rose-ringed Parakeets can be identified by their long tails (about the same length as their lime green bodies), red beaks, and loud call. Mature male parakeets have a black or rose-colored ring around their cheeks. Report RRP sightings to www.643pest.org or call (808) 643-PEST. Photo: Bishop Museum.

MISC is asking the Maui community to help in early detection efforts by reporting any sightings of these few remaining birds. Report any sighting of Rose-ringed Parakeets on Maui to www.643pest.org or call (808) 643-PEST (7378). Questions may be directed to miscpr@hawaii.edu.

MISC appreciates your support in the rapid response effort to keep Maui free of this invasive species!

Press Release: New invasive little fire ant population discovered in Huelo

Posted on June 3, 2021 by Serena Fukushima

PRESS RELEASE

Date: June 3, 2021 FOR IMMEDIATE RELEASE
Subject: New invasive little fire ant population discovered in Huelo
Contact: Serena Fukushima, Public Relations and Educational Specialist
Maui Invasive Species Committee
PH: (808) 344-2756
Email: miscpr@hawaii.edu

In early May, the Maui Invasive Species Committee (MISC) received a voicemail from a husband and wife describing stinging ants encountered on the property where they live in Huelo. They explained that tenants on the property doing yardwork experienced stings on their torsos by tiny ants. MISC and the Hawaiʻi Department of Agriculture surveyed the property and positively identified little fire ants (LFA). The MISC little fire ant team thoroughly mapped the infestation and treatments have already begun. MISC is working with the landowner and tenants on determining where the source of this new little fire ant infestation came from. Despite the proximity of this site to another infestation in Huelo, these sites do not appear to be related.

“If the community continues to be our eyes and ears by reporting suspect ants, we can stop the little fire ant from becoming established on Maui,” says Adam Radford, Manager of the Maui Invasive Species Committee. “reporting is critical to finding these invasive ant populations and eliminating them, so getting into the habit of contacting MISC when you get stung by a suspect ant is a great way to protect our island from these invasive species. If you get a sting, give us a ring!”

Community efforts have led to the detection of 12 of 18 known infestations of little fire ants on Maui. Once detected, each infestation is treated for approximately one year, then monitored. There are only six sites, including this one, where little ants are still present and under active control.

On Maui, funding from the County of Maui and the Hawaii Invasive Species Council supports little fire ant control efforts. The Hawaii Department of Agriculture inspects incoming plant material for invasive pests, preventing additional infestations, and assists MISC with survey and control efforts.

Little fire ants have become widespread on Hawaii Island. Animals often leave the areas where ants are established, as do hikers, farmers, and hunters. When little fire ants invade yards and homes, pets can be blinded, and residents choose to move.

Community efforts are essential to keeping invasive ants from becoming widespread. MISC recommends collecting ants in your yard for identification at least once per year, and every time new materials such as mulch or nursery plants are purchased. It only takes a few minutes to test for LFA:

Smear a tiny bit of peanut butter (or mayonnaise if peanut allergies are a concern) on several thin strips of cardboard, and place them in shady places in your yard. After 45 minutes, collect the samples with ants, place them in a plastic bag labeled with your name, address, and contact information, and freeze for 24 hours to kill the ants. Mail them to your local Invasive Species Committee. On Maui, please send them to MISC, P.O. Box 983, Makawao, HI 96768.

Visit stoptheant.org to find out more information on collecting ant samples and the status of LFA on Maui and throughout the state. Contact MISC with concerns, questions, or reports at 808-573-6472 or miscants@hawaii.edu. Reports can also be submitted through 643PEST.org.

Haʻikū Residents bring back quiet nights through MISC Community Coqui Control Program

Posted on December 4, 2020 by Susan Frett

Haʻikū communities are taking back their quiet nights from noisy, invasive coqui frogs, with tools and training from the Maui Invasive Species Committee (MISC). MISC is currently working with five Haʻikū neighborhoods –Haʻikū Hill, Haʻikū Mauka, Haʻikū Makai, Lower Kokomo and Akoa/Ala Olu/Makaio. The program is ready to assist and empower more Haʻikū residents in the fight against this invasive species to protect their way of life and health of our native ecosystems.

Ha’ikū residents support each other in controlling coqui frogs on their properties with support from MISCʻs Community Coqui Control Program.

MISC recognized that in addition to strong support from the County of Maui and State of Hawai’i, containing and eradicating coqui in Haʻikū would require strong engagement at a neighborhood level. MISC launched the program to support and expand on existing community coqui control efforts by residents. MISC provides training, equipment, and citric acid solution (a food additive mixed with water). Community members provide boots on the ground – removing vegetation, hauling hoses, and dousing infested areas with citric acid solution. And it’s working. According to Haʻikū Hill team leader John Phelps, “Spraying each month has reduced the number of frogs on each property from hundreds to only a handful.” Neighbors working together can be more effective than independent control efforts, as coqui can quickly move into untreated areas or reinfest properties without a consistent effort. Participants report an additional benefit: the program is a good opportunity to get involved and meet their neighbors. MISC follows all social distancing and mask-wearing protocols whenever working in the community and all control work is conducted outdoors.

A Haʻikū residents sprays citric acid to control coqui on his property.

MISC provides different levels of support, depending on community need and participation. Individual residents can receive free powdered citric acid to control coqui on their property once MISC has confirmed that coqui are present. Residents can also borrow a 9-gallon walk-behind sprayer or a 100-gallon sprayer that fits in the back of a pickup truck. MISC provides training on how to effectively use the sprayers.

When three or more neighbors agree to work together across their properties, MISC provides a 100-gallon sprayer to participating residents every six weeks and helps residents with spray operations if needed. For larger groups of neighbors (at least nine committed households, plus a person who serves as a point of contact) MISC provides a reservoir of pre-mixed citric acid during the specified control week on a six week rotation. Participants report that having mixed citric acid in advance has been a “game changer” as it allows the team to focus directly on control activities. In two neighborhoods, the community groups proposed using a pipeline to effectively treat a larger area. MISC and the residents worked together to design and install the systems.

MISC provides a variety of sprayers to residents wanting to control coqui frogs on their properties.

Over the years, MISC has been able to eradicate 21 coqui populations on the island. Abe Vandenberg, MISC Coqui Field Coordinator, says the key to those successes has been persistence and consistency. He emphasizes the importance of community efforts, noting record levels of participation last summer, “Local engagement is a huge help to the island-wide coqui control strategy. As more community members help remove coqui from their own backyards, they allow MISC staff to take on more challenging work in the gulches and other areas with difficult access. Working the process of small wins will lead us toward the biggest possible success – a coqui-free Maui.”

Mark Blietz Receives 2020 Mālama i ka ʻĀina Award

Posted on November 25, 2020 by Lissa Strohecker

Mark Blietz, owner of Northshore Tropicals in Haʻikū, is the 2020 recipient of the Mālama i ka ʻĀina. The award is given each year to recognize the efforts of individuals in the landscape and agricultural community towards stopping the spread of invasive species in Maui County. The award is presented by the Maui Invasive Species Committee, the Maui Association of Landscape Professionals, and the County of Maui.

Blietz is a well-known nursery owner who has led by example throughout his career, both in the landscaping community and throughout Maui. He and his family have been in the nursery business for over 30 years and throughout that time, he has been active locally in the Maui Orchid Society and nationally as a judge in the American Orchid Society. Blietz has been proactive in dealing with invasive species and urges others to do the same. When the stinging nettle caterpillar arrived to Maui in 2008, he started controlling it around his nursery himself to keep from spreading it – he continues to control invasive species, currently working to keep coqui and ivy gourd out of his nursery.

But it was his generosity over the last year that led to his nomination for the award. The Maui Invasive Species Committee (MISC) needed temporary storage and facilities to keep their crews working after they lost access to the facility they had been in for over a decade. Blietz shared his property and barn, keeping MISC operational until a new baseyard became available. “Mark saved the day for MISC…MISC couldn’t have kept working to protect Maui County from invasive species without his help” said Adam Radford, MISC Manager, in acknowledgement of Blietz’s efforts.

In accepting the award, Blietz encouraged community action. “There’s so much that we, as stewards of the land, can do to protect our ʻāina from invasive species. Simply being able to identify them and letting them [MISC] know” he said.

Press Release: Haʻikū residents report stinging ants, uncovering a small population of invasive little fire ants

Thanks again to the backyard efforts of Maui residents, a recently-detected population of little fire ants will be eradicated. This infestation is in Haʻikū, off Kaupakalua road. The Maui Invasive Species Committee (MISC) estimates the ants have spread across four acres.

Maui residents Janet Mercer and Patti Hawkins reported the ants to MISC in late September. After several months away they returned to their home to find a new tenant: tiny, orange ants had spread throughout their yard and house. Initially, Mercer and Hawkins tried to control the ants with liquid ant baits from the hardware store but the ants ignored the household pesticide. The pests however, did not ignore the couple; even inside their home, they were getting stung.

Little fire ants form supercolonies by cooperating with each other. They effectively outcompete other ant species and take advantage of all possible habitat, colonizing trees and the ground. While they prefer to be outside, once they are established they start to explore new environments – including those occupied by people.

Hawkins is highly reactive to insect stings “I seem to be the canary in the coal mine,” she jokes. But even she was surprised by the pain delivered by these tiny ants. “It was like a bee, it kept going for 10-15 minutes or more after it stung. Then they would welt up,” she explains.

Hawkins told the story to a friend who suggested they might be little fire ants and that she should collect and submit a sample. “I put a little peanut butter out there and, wham. I couldn’t believe it. … I came back less than an hour later and the sticks were swarmed.” She brought the sample to an employee with the Maui Invasive Species Committee (MISC) who confirmed that the ants were indeed the little fire ant.

MISC and the Hawaiʻi Department of Agriculture (HDOA) have surveyed the couple’s home and surrounding properties. The Hawaiʻi Department of Agriculture has done trace-forward testing – looking at places where potted plants or material had been moved from the infested area to see if any ants may have hitchhiked a ride. Based on their findings, the infestation is contained to four acre, but the source of the infestation is not known. Given the spread, it’s likely that ants have been present for several years.

Coincidentally, the infestation was detected just before little fire ant awareness month, an annual event where Hawaiʻi residents are encouraged to collect and submit samples of ants from their homes to find infestation of little fire ants and other invasive ants while they can still be controlled. Community efforts have led to the detection of 11 of 17 known infestations of little fire ants on Maui. Once detected, each infestation is treated for approximately one year, then monitored. There are only eight sites, including Kaupakalua, where little ants are still present and under active control.

“If people keep paying attention, and collecting and reporting suspect ants, we can stop the little fire ant from becoming established on Maui,” says Adam Radford, manager of the Maui Invasive Species Committee. “The Hawaiʻi Department of Agriculture is able to inspect incoming material for LFA and other pests, MISC crews conduct surveys, but public reporting is critical to finding these invasive ant populations and eliminating them.” On Maui, funding from the County of Maui and the Hawaiʻi Invasive Species Council supports control efforts.

Little fire ants have become widespread on Hawaiʻi Island. Animals often leave the areas where ants are established as do hikers and hunters. When little fire ants invade yards and homes, pets can be blinded.

Community efforts are essential to keeping invasive ants from becoming widespread. MISC recommends collecting ants for identification at least one time per year. It only takes a few minutes:

Smear a tiny bit of peanut butter (or mayonnaise if peanut allergies are a concern) on several sticks, coffee stirrers, or pieces of cardboard, and place them in shady places in your yard. Set a timer for 45 minutes.
After 45 minutes, collect the ants, place them in a plastic bag labeled with your name, address, and contact information, and freeze them overnight.
Mail them to your local Invasive Species Committee. On Maui, send them to MISC, P.O. Box 983, Makawao, HI 96768.

Visit stoptheant.org to find out more information on collecting ant samples of ants and the status of LFA on Maui and throughout the state. Contact MISC with concerns, questions, or reports at 808-573-6472 or miscants@hawaii.edu. Reports can also be submitted through 643PEST.org.

The little fire ant (LFA) has been detected on the campus of Lahainaluna High School

Little fire ants climb along a hibiscus flower.

A report of little fire ants on the campus of Lahainaluna High School has been confirmed by the Hawaii Department of Agriculture (HDOA) and Maui Invasive Species Committee (MISC). This is the first detection of the invasive little fire ants at a school in Maui County. Though schools on Hawaii Island are burdened with addressing the stinging ants on school grounds, MISC is able to help on Maui.

“Proactive efforts on the part of the Lahainaluna staff – in recognizing little fire ants and submitting a sample – resulted in early detection of a relatively small infestation. Finding them early is the key to successful and timely eradication,” says MISC manager, Adam Radford.

Based on initial inspection, the infestation is just over one-quarter of an acre and limited to a section of potted plants brought to the campus several years ago as part of the school’s agriculture program. Staff suspected little fire ants were present in December and collected and submitted a sample of the pests to the Maui Invasive Species Committee in January. Two comprehensive treatments of the infestation have already occurred. The next treatment is scheduled for mid-June and treatments will continue for one year.

Once identified, this site posed little risk to the community and is the smallest infestation detected on Maui in recent years. The infested material has been quarantined on-site since detection. Without human involvement, little fire ants spread slowly, particularly in dry arid regions as the ants are a rainforest species native to South America. Moving soil and plants that have little fire ants are how they are able to spread quickly over large distances.

The school conducts occasional plant sales. The Spring Plant Sale was held in May 2019, at the Lahaina Cannery Mall. Another plant sale was held on campus in November of 2019. There is a chance that Infested plants were sold. “I encourage anyone who may have recently purchased plants from Lahainaluna High School, to test your yards or garden areas,” says Jeri Dean, TA Acting Principal of Lahainaluna.

Community assistance – testing for little fire ants and reporting stinging ants – have led to the majority LFA detections on Maui.

MISC recommends that Maui residents survey their yards for little fire ants once per year. Additionally, quarantine new plants, mulch, or soil before planting or distributing throughout the property and test for little fire ants. Moving construction equipment and building material is an additional vector for LFA throughout the state. Any material stored outside for months or more should be tested.

Small red ants, particularly those that fall from overhanging vegetation, stinging people on the back of the neck, warrant immediate collection and reporting. Ant samples can be collected for identification by smearing a thin layer of peanut butter on a stick and leaving it outside near where ants are found for 45 minutes. Bag the sample and place it in a freezer for 24 hours, then mail the sample to the Maui Invasive Species Committee at PO Box 983, Makawao, HI 96768, including contact information. Samples can also be mailed to the Hawaii Department of Agriculture at 635 Mua St, Kahului, 96732. If you have questions, please call 573-MISC (6472).

This latest detection brings the total number of infestation sites on the Valley Isle to 16. Seven sites are being actively treated. The remaining nine sites are regularly surveyed to ensure the ants have been eradicated at those locations.

The only other known site on West Maui is in Kapalua. Originally covering 12 acres, the stinging ants were reported by an area resident in 2016. The Kapalua site is now in a monitoring phase and there is no known link between the Lahainaluna infestation and the one in Kapalua. Visit stoptheant.org to find out more information on collecting samples of ants and the status of LFA on Maui and throughout the state.

The little fire ant (LFA) has been detected in the Twin Falls area, Huelo, Maui.

Posted on November 27, 2019 by Lissa Strohecker

An infestation of little fire ants (LFA) has been detected at an area known as Twin Falls, in Huelo, East Maui. The infestation was reported in early November, by both an area resident living within the infested zone and a former employee of the Maui Invasive Species Committee (MISC) who had been stung while visiting the popular hiking and swimming site off the Hana Highway.

On Hawaii Island, residents and visitors have abandoned popular trails and waterfall hikes because of the rain of stinging ants that fall on them as they pass through overhanging vegetation.

On November 14th, two dozen people – both local residents and community members from elsewhere on Maui, worked with MISC and Hawaii Department of Agriculture personnel to place and collect samples to determine the size and spread of the infestation.

At approximately eight acres, the infestation encompasses several homes and some areas frequented by hikers and swimmers. Samples collected downstream from the core of the infestation have little fire ants – additional survey work will determine if the ants have spread along the waterway.

This find marks the third detection of the year on Maui, consistent with the trend of detecting two to three little fire ant populations each year. “We are fortunate to have strong community awareness – public reporting of little fire ants continues to be the most effective way to find populations,” says Adam Radford, MISC manager. MISC is actively treating ten populations of little fire ants.

Thanks to funding from Maui County and the Hawaii Invasive Species Council the LFA response team is expanding by two to address this growing problem. MISC continues to partner with Maui HDOA staff in following up on reports and treatment efforts from Kapalua to Hana. The most important part of successful containment is community participation.

“If we are to keep little fire ants from becoming established, we need to find the populations early while they are still small – – we need the community to remain vigilant, actively checking for little fire ants whenever new material (potted plants, mulch, or anything stored outside) is introduced to their homes and reporting suspected populations of little fire ants early on. We know new populations will continue to be discovered, and we’re prepared for that, we’ve been highly successful at removal throughout Maui,” says Radford.

There will be a community meeting on Thursday, December 5^th, at 6:00 pm at the Haiku Community Center to discuss what is known about the Twin Falls little fire ant infestation and plans for eradication.
