3145. Lockwood, J, W. Kemp, and J. Onsager. 1988. Long-term, large-scale effects of insecticidal control on rangeland grasshopper populations.. J. Economic Entomology 81:1259-1264.
Intensive application of broad spectrum insecticides to control economically damaging populations of rangeland grasshoppers in Wyoming appears to have increased the probability, duration, and stability of grasshopper outbreaks. The study compares about 30 years of data on grasshopper infestations and pesticide management between bordering counties. The county with greater insecticide treatment had longer, more stable, and more frequent infestations that were economically damaging. This was attributed to the reduction of parasites and predators of grasshoppers.
