Abstract

The aim of the present study is to evaluate the effect of certain petroleum oil formulations on some phytophagous mites, i.e. Eutetranychus orientalis Klein and Tetranychus urticae Koch. Moreover, effect of these formulations on predacious mite Amblyseius gossipi El-Badry was also evaluated to predict suitability of petroleum oil formulations to be as a component of integrated mite control. Results indicated that albulium 80% EC, KZ 95% EC, shokrona super 95% EC, and shokrona 95% EC were most toxic to adult females of E. orientalis than that of T. urticae and significantly reduced their fecundity. The response of eggs to the mineral oils varied according to their age. The predacious mite A. gossipi shows more resistance to petroleum oil than phytophagus ones. Under field conditions shokrona and shokrona super exhibited satisfactory effectiveness against phytophagous mites on fruit trees a little adverse effect on predacious mite was recorded comparing with synthetic acaricides.
