Cropping Systems, Insect Movement, and the Spread of Insect-Transmitted Diseases in Cropsbeing replaced by large-scale, input-intensive monocultures. It is clear that insecticide abuse and widespread dependence on single crop genotypes have resulted in many problems for the farmer, the environment, and the health and safety of rural workers (Bull, 1982). Along with other insect pests, i

In a recent review of the available world literature, Andow (1983) found that in a total of 617 examples, the population densities of 66% of the monophagous herbivores studied decreased in the diversified system when compared to the corresponding monoculture. Many studies reported that pr
