The Problem:
Avian malaria, spread by mosquitoes, is devastating native Hawaiian forest birds, notably honeycreepers.
Many honeycreeper species are already extinct, and the remaining ones are threatened as climate change allows mosquitoes to move to higher elevations.
The ‘akikiki is now considered functionally extinct in the wild.
The kiwikiu,or Maui parrotbill,is another endangered species of honeycreeper. It lives on Maui.
The Solution:
Environmental organizations are releasing male mosquitoes with a Wolbachia bacteria strain into honeycreeper habitats. These male mosquitoes don’t bite and, when they mate with local females, their eggs don’t hatch, reducing the mosquito population.
Initially, this was done via helicopters, but now they are using drones.
This technique is called the incompatible insect technique (IIT).
