Public health: Control of mosquito-borne encephalitis
by William C. Reeves , Marilyn Milby , James L. Hardy
pp6-7, doi#10.3733/ca.v034n03p6
Abstract
The mosquito control program in California has been uniquely successful, and for practical purposes, the major mosquito-borne diseases, such as encephalitis and malaria, have been effectively controlled in the state in recent years. Much of the original research leading to this success was done by the University of California School of Public Health. Current research is directed at preventing a resurgence of mosquito-borne diseases, with emphasis on surveillance and vector suppression.The major mosquito-borne diseases have been effectively controlled in California. Research i s now directed at preventing their resurgence.

Biology, ecology and ethology: Mosquitoes—a by-product of rice culture
by Robert K. Washino
pp10-12, doi#10.3733/ca.v034n03p10
Abstract
Research on mosquito biology and ecology yields fundamental knowledge of the behavior, habits, breeding preferences, flight range, survival rates, and other characteristics of pest and disease-vector mosquitoes-information essential for effective planning and execution of control programs. Ecological studies assume greater importance in California than elsewhere because of the state's diverse climate and topography. Forty-nine mosquito species are found here, of which six are confirmed disease vectors.Knowledge of the behavior and characteristics o f mosquitoes i s the first step in finding more effective control methods.

Biological control and genetics: BTI — a potent new biological weapon
by Richard Garcia , Brian A. Federici , Irvin M. Hall , Mir S. Mulla , Charles H. Schaefer
pp17-19, doi#10.3733/ca.v034n03p17
Abstract
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.

Chemical control: Conventional and nonconventional chemicals for mosquito control
by Charles H. Schaefer , Mir S. Mulla
pp28-29, doi#10.3733/ca.v034n03p28
Abstract
Although they have fallen into disfavor because of mosquito resistance and other problems, chemicals are still the fastest and most effective way to suppress mosquitoes. The thrust of nearly all University research in this area is on the development and evaluation of narrow spectrum insecticides that selectively kill mosquitoes with minimal injury to natural enemies and nontarget species. Promising new developments include insect growth regulators, which interfere with the growth processes of the mosquito larvae, juvenile hormones, mosquito attractants, repellents, and other substances derived from natural products.Despite problems, chemicals are still the fastest and most effective means of mosquit control. University scientists are working on narrow-spectrum insecticides that kill mosquitoes but don't harm other species.

Physical and cultural control: Reclaiming alkali soils to reduce mosquito breeding sites
by Charles H. Schaefer , William E. Wildman
pp36, doi#10.3733/ca.v034n03p36
Abstract
Physical control involves modification of the environment to reduce or eliminate mosquito breeding places: drainage, diking, filling, leveling, or other engineering works. Cultural control aims for mosquito reduction through management of soils and vegetation that contribute to mosquito problems. Researchers are investigating the effects of conventional drainage and ditching practices on natural flow and fauna in salt marshes and studying ways to reclaim impermeable alkali soils, which are important sources of mosquitoes in some areas.Physical and cultural control methods seek to reduce mosquito breeding sources, whileminimizing possible adverse effects on the environment.
