PETROLEUM OILS AS A COMPONENT OF INTEGRATED PEST-MANAGEMENT OF PHYTOPHAGOUS MITES

The aim of the present study is to evaluate the effect of certain petr oleum oil formulations on some phytophagous mites, i.e. Eutetranychus orientalis Klein and Tetranychus urticae Koch. Moreover, effect of the se formulations on predacious mite Amblyseius gossipi El-Badry was als o evaluated to predict suitability of petroleum oil formulations to be as a component of integrated mite control. Results indicated that alb ulium 80% EC, KZ 95% EC, shokrona super 95% EC, and shokrona 95% EC we re more toxic to adult females of E. orientalis than that of T. urtica e and significantly reduced their fecundity. The response of eggs to t he mineral oils varied according to their age. The predacious mite A. gossipi shows more resistance to petroleum oil than phytophagous ones. Under field conditions shokrona and shokrona super exhibite satisfact ory effectiveness against phytophagous mites on fruit trees and a litt le adverse effect on predacious mite was recorded comparing with synet hetic acaricides.
