Possible residual effect of pesticide on Bactrocera oleae Rossi (Diptera:Tephritidae) adults

Abstract

Adult olive fruit flies appeared to be affected by residual insectide deposits on the surface of the olive fruit. Females initially knocked down did not recover, and all died, but knocked down males recovered by the next day after washing their bodies with water. In future experiments with olives of unknown history, the researcher is advised to wash the fruit thoroughly before offering then to flies.
