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:
“Imagine believing in the control of inflation by curbing the money supply! That is like deciding to stop your dog fouling the sidewalk by plugging up its rear end. It is highly unlikely to succeed, but if it does it kills the hound.”
—Michael D. Stephens. “On Sinai, There’s No Economics,” New York Times (Nov. 13, 1981)
“Being a parent is such serious business that we dare not take it too seriously. Children are inherently funny. So are parents. We all are at our funniest when we are desperately struggling to appear to be in control of a new situation.”
—Lawrence Kutner (20th century)
“The inability to control our children’s behavior feels the same as not being able to control it in ourselves. And the fact is that primitive behavior in children does unleash primitive behavior in mothers. That’s what frightens mothers most. For young children, even when out of control, do not have the power to destroy their mothers, but mothers who are out of control feel that they may destroy their children.”
—Elaine Heffner (20th century)
