Millions of Mosquitoes May Be The Only Hope To Save Hawaii’s Honeycreepers

Facing the Future: An Uncertain Hope for Honeycreepers

IIT offers a beacon of hope for the honeycreepers’ future, but it’s only one piece of the puzzle. It will take years to eliminate mosquitoes from the islands, and a multipronged approach is necessary. Researchers are also studying how some honeycreepers have developed immunity to avian malaria, hoping to create vaccines or probiotics.

Hawaii’s honeycreepers are not just canaries in the coal mine; they are a testament to our responsibility to protect the unique and fragile ecosystems that make our world so rich and diverse. The battle to save the honeycreepers is a race against time, but it’s a race we must win for the sake of Hawaii’s natural heritage and the planet’s biodiversity.

The beautiful Hawaiian archipelago is home to a collection of rare birds known as honeycreepers, along with a thriving array of flora and fauna. These vibrant birds form the foundation of Hawaiian culture and ecology. They are descended from finches that came in Hawaii over millions of years ago.

However, there is a grave threat to the honeycreepers’ survival, and time is running out. The offenders? Avian malaria and invasive mosquitoes.

Now, a novel approach known as the Incompatible Insect Technique (IIT) might offer these unusual birds a chance.

Preserving honeycreepers is not just about saving a species but also safeguarding Hawaii's unique ecosystems.

Hawaii’s honeycreepers as symbols
The honeycreepers are more than simply birds; they play a crucial role in the ecosystem and culture of Hawaii. According to statistics from the U.S. Geological Survey, only 17 of these avian beauties that once adorned the islands in excess of 50 species are still alive. Their populations have suffered greatly as a result of exotic predators, habitat loss, and the deadly avian malaria caused by invasive Culex quinquefasciatus mosquitoes. An inventive strategy is required to conserve these birds.

Hawaii's honeycreepers serve as an example of the challenges faced by island species with small distributions.

The Technique of the Incompatible Insect
The Incompatible Insect Technique (IIT), according to the National Park Service, is a ray of hope for honeycreepers. IIT is now being developed to fight the mosquito problem that afflicts the birds instead of being traditionally utilized to manage disease-carrying mosquitoes that impact humans. The technique relies on Wolbachia bacterium, which is naturally present in mosquito bellies and affects the insects’ capacity for reproduction. The idea is to release male mosquitoes that have been specially produced and are carrying a new strain of Wolbachia into the wild. By mating with the indigenous females, these males will prevent them from conceiving live young. The honeycreepers will subsequently find some relief since the mosquito population will then drastically decline.

Success with IIT depends on preventing the new Wolbachia strain from infecting local mosquitoes.

Trial by Mosquitoes

The Birds, Not Mosquitoes consortium has already conducted trial studies, releasing thousands of IIT mosquitoes to study their behavior. Results suggest that the approach works, but closer mosquito releases will be needed.

In the next phase, beginning in November, 250,000 treated mosquitoes will be dropped twice a week over approximately 3,000 acres in east Maui, Scientific American reports. These mosquitoes will be contained in biodegradable capsules. However, success depends on ensuring the new Wolbachia strain doesn’t infect local mosquitoes, which would thwart the project’s goals.

While the IIT approach is not a permanent solution, it offers a critical lifeline for the honeycreepers. The U.S. Department of the Interior is meanwhile establishing captive care programs, relocating at-risk honeycreepers, and developing gene drive technology to increase the birds’ malaria resistance.

Conservation efforts for honeycreepers are a race against time, with extinction looming.
