Purdue researchers look to develop new
method to control disease-carrying insects

February 2, 2012

Purdue researchers are discovering the next generation of insecticides directed at disease-carrying insects like mosquitoes, ticks and tsetse flies, which could help professionals in the human health, veterinary and crop production sectors.

Catherine A. Hill, associate professor of entomology in the College of Agriculture, and Val J. Watts, professor of medicinal chemistry and molecular pharmacology in the College of Pharmacy, say vector insects - which carry and transmit infectious pathogens or parasites to other living organisms - are developing resistance to insecticides sprayed in the air or embedded in bed nets. The increased resistance makes insecticides less effective.
