Entomology - Hays, KS
The entomology program at ARCH has a broad mandate to develop IPM strategies for rain-fed agriculture in the region. Integrated pest management means combining cultural, chemical and biological control tactics to achieve crop protection in the most cost-effective way possible. The goal is cost-effective reduction of crop losses to insects, and it is important to remember that this does not always require lethal control of insects. Regional crops have a generally low per-acre value relative to more intensive forms of agriculture and this presents a major challenge: pest control tactics must be cheap to implement or they will yield no economic benefit for the farmer. Under these conditions, sound pest management strategies are more often preventative than curative in nature. The key to IPM is a sound understanding of the biology and ecology of the pest, and the physical and environmental factors affecting its behavior and population dynamics. Consequently, our research projects range from very basic biological studies of insect behavior under controlled conditions, all the way to field trials designed to evaluate crop protection tactics at a commercial farm scale. Our program also supplies general entomology extension support for Northwestern and Central Kansas.
