Mosquito Aedes aegypti

Opposition has delayed the planned test of releasing sterile males of the mosquito Aedes aegypti in California. The method to be tested could perhaps wipe out that pest in California.

Aedes aegypti in California is an intrusive species, so its effects on ecosystems are essentially negative. Species which depend on eating mosquitoes must have eaten only the native species until recently, and can still do so. The benefit to be obtained by eradicating Aedes aegypti in California, in reduced disease and reduce pesticide use, is surely enormous.

The state should insist on researching what can be tested, and developing further precautions for aborting the experiment early. But don't let Aedes aegypti hang around for long.
