Abstract

The present work were determined to evaluate the latent effect of three acaricides Ortus Super®5%EC, Vertimec® 1.8% EC and Delmite®7.5% SC on the biological aspects of the coccinellid predator, Stethorus gilvifrons Mulsant as predator of the tow spotted mite, Tetranychus urticae Koch at laboratory conditions (30±1C and 70±5% RH.). All experimented acaricides were affected on the biology of S. gilvifrons. Vertimec® was the most effective on T. urticae and associated predator, S.  gilvifrons than Ortus Super® and Delmite®. Using Delmite® proved to be the safest amongst other acaricides on this predator.
