Agricultural economists have long recognized pest populations as common property resources, and, as such, pest control through chemical pesticide application involves a tradeoff between increased crop yields and reduced environmental quality (Carlson; Regev et al.). Integrated pest management (IPM) attempts to minimize this tradeoff by substituting pest information and management skills for chemical pesticides. In part, IPM involves monitoring pest populations in order to utilize beneficial biological interactions. Weather patterns, stage of crop growth, and natural biological enemies of pests are among the factors included in IPM. In addition, entomologists have extended the integrated control concept to include selective rather than nonselective pesticide application that is applied only when pest populations exceed the “economic threshold” level (Hall and Norgaard). In an earlier economic analysis of IPM, Hall concluded that the major advantages of IPM are: (1) a substantial reduction in overall pesticide use, (2) no significant reduction in profits, (3) no significant loss of yields, (4) an overall reduction in pest management costs, and (5) a reduction in risk for the producers.

As part of a continual search for potential pathogens of insects for use in biological control or on an integrated pest management program, two bacilliform virus-like particles (VLP) of similar morphology have been found in the Mexican bean beetle Epilachna varivestis Mulsant and the house cricket, Acheta domesticus (L. ).Tissues of diseased larvae and adults of E. varivestis and all developmental stages of A. domesticus were fixed according to procedures previously described. While the bean beetles displayed no external symptoms, the diseased crickets displayed a twitching and shaking of the metathoracic legs and a lowered rate of activity.Examinations of larvae and adult Mexican bean beetles collected in the field in 1976 and 1977 in Maryland and field collected specimens brought into the lab in the fall and reared through several generations revealed that specimens from each collection contained vesicles in the cytoplasm of the midgut filled with hundreds of these VLP's which were enveloped and measured approximately 16-25 nm x 55-110 nm, the shorter VLP's generally having the greater width (Fig. 1).
