A Model for Predicting Stable Fly Populations

“Stable fly populations fluctuate tremendously not only seasonally but also from year to year. An important component of any integrated pest management program is to know the current trend in the population. As a pest population approaches the economic injury level, one would like to know if the population is going to continue to increase, meriting control measures, or if the population is approaching its peak and will naturally decline in the near future,” says Taylor, research entomologist at the USDA-ARS Agroecosystem Management Research unit.

“In this study, we show that stable fly populations are responding to temperature and precipitation and their dynamics can be predicted using those variables,” Taylor continues. “This information permits more efficient use of control technologies. Negating the need for control using chemical agents when a population is at the cusp of a decline, for instance, reduces selection for insecticide resistance on that population and will slow the development of overall resistance.”
