Control
The main way to control avian malaria is to control mosquito populations. Hunting and removing pigs helps, because wallows from feral pigs and hollowed out logs of the native hapu'u ferns provide dirty standing water where the mosquito breeds (USDI and USGS 2005). Around houses, reducing the number of potential water catchment containers helps reduce the mosquito breeding sites (SPREP Undated). However, in Hawaii attempts to control the mosquitoes by larval habitat reduction and larvicide use have not eliminated the threat.
It may also be possible to find birds that are resistant to malaria, collect eggs and raise young birds for re-introduction into areas where birds are not resistant, giving the species a head-start on spreading resistance. There is evidence for evolution of resistance to avian malaria in two endemic species, Oahu Amakihi and Hawaii Amakihi. If other species can be preserved for long enough, they may evolve resistance as well. One tactic would be to reforest high-elevation areas on the island of Hawai'i, for example above the refuge of Hakalau on land managed by the Department of Hawaiian Homelands. This could give birds more time to adapt before climate change or mosquito evolution bring avian malaria to the last remaining bird populations.

Famous quotes containing the word control:
“I candidly confess that I have ever looked on Cuba as the most interesting addition which could ever be made to our system of States. The control which, with Florida, this island would give us over the Gulf of Mexico, and the countries and isthmus bordering on it, as well as all those whose waters flow into it, would fill up the measure of our political well-being.”
—Thomas Jefferson (1743–1826)
“He took control of me for forty-five minutes. This time I’ll have control over him for the rest of his life. If he gets out fifteen years from now, I’ll know. I’ll check on him every three months through police computers. If he makes one mistake he’s going down again. I’ll make sure. I’m his worst enemy now.”
—Elizabeth Wilson, U.S. crime victim. As quoted in People magazine, p. 88 (May 31, 1993)
“The human mind is indeed a cave swarming with strange forms of life, most of them unconscious and unilluminated. Unless we can understand something as to how the motives that issue from this obscurity are generated, we can hardly hope to foresee or control them.”
—Charles Horton Cooley (1864–1929)
