Effect of some acaricides on the biology of Stethorus gilvifrons mulsant (coleoptera-coccinellidae)‎ as predator of Tetranychus urticae koch

الملخص EN

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 ± 1◦C 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.
