The Colorado potato beetle, Leptinotarsa decemlineata (Say), is a serious pest of tomatoes grown in this country. This beetle is also developing resistance to several classes of chemical insecticides including most of the carbamates, chlorinated hydrocarbons, and organophosphates (Forgash 1981). and most recently to the pyrethroids. According to figures in a report released by Schwartz and Klassen (1981). the value of the tomato crop in the CSA in 1978 was placed at $914,121,000 and crop loss due to Colorado potato beetle (CPB) damage alone would be 93% of its value if no control were undertaken. These figures along with the fact that the CPB is developing resistance dictate the need for. and development of, alternative control measures.
