To evaluate and monitor insecticide resistance in onion thrips Thrips tabaci on onion (Allium cepa), we conducted a study using three field populations in the Treasure Valley of eastern Oregon and southwestern Idaho using the insecticides Lannate (methomyl) and Exirel (cyantraniliprole). To evaluate these two insecticides, biological assays were conducted...
Endogenous inhibitors of insect microsomal oxidases are a serious
problem in in-vitro studies of insecticide metabolism.
Their number,
chemical nature, modes of action, and their effectiveness as inhibitors
are unknown.
In the case of house flies, there may be as many as
four inhibitors.
The most important of these is...
Factors influencing pesticide susceptibility and
resistance were studied in Psylla pyricola Foerster, and
its mirid predator, Deraeocoris brevis Knight in the
Rogue River Valley, Oregon. Factors studied were at the
biochemical, life history, and population ecology
levels.
Studies on detoxification enzymes showed that
glutathione S-transferase and cytochrome P-450
monooxygenase activities...
The diamondback moth (Plutella xylostella L.) is a major
pest of crucifer crops worldwide. It is a particularly
important problem in Southeast Asia where climatic
conditions favor a short generation time and rapid
proliferation. In countries such as Thailand, the
diamondback moth has apparently become resistant to all
classes of...
