Abstract
The use of residual insecticides is increasing in insect control programs. In practice all insects do not receive lethal dosages, possibly because of uneven application of insecticide and the failure of some insects to come in contact with treated surfaces. This study was designed to determine the rate of oviposition of adult females of Tribolium confusum Duv. surviving exposure to DDT residues and to compare this rate with that of unexposed females.
