Variability in susceptibility of insect pests of stored products to insecticides.

Insect pests of public health importance were the first among which the development of highly insecticide resistant strains was shown to be widespread. More recently, numerous instances of resistance among economically important insect pests of growing crops have been revealed. The relative scarcity of reported resistance in stored-products pests is probably a reflection of fewer investigations and fewer instances of continued insecticidal controls. The possible development of resistance at a future date in stored-products pests and the chance that one might avoid such development if it can be foreseen should be adequate justification for the present investigation. It was felt that the occurrence of stored-products pests as isolated islands of population might enhance the selection of resistant strains locally and also allow their eradication if they are discovered, making this a worthwhile area for study.
