Biological control and genetics: BTI — a potent new biological weapon
Control of mosquitoes through exploitation of their natural enemies to suppress them has been given high priority in California for many years. More studies have been approved and more funds expended on biological controls than on any other research category. Investigations have been pursued on a broad range of bioagents—mosquito predator fish, aquatic insects, fungal and bacterial pathogens, and nematode parasites. Bacillus thuringiensis var. israelensis (BTI) is an exciting new bioagent under study and has prospects of becoming an important adjunct to biological control.Research on use of natural enemies t o suppress mosquitoes has had high priority in California for many years. New biocontrol agents offer exciting possibilities.
