Abstract
The present study was carried out to examine :1-The toxic effect of tested compounds against the egg and adult female of the two spiders spotted mite2-The toxic effect of tested compounds against adut female of the predatore mite.3-The side effect of the sub-lathal doses of the tested compounds on some biological aspects of spider mite and its predatory mite fecundity and hatchability of eggs for prey, feeding behaviour fecundity and hatchability for the predator. 4-The development of resistance in suscebtible trains of T.urticae for chemicals.5- The soecific activity of acetycholine esterase and glutathion transferase enzyme under laboratory conditions was determined to study the mechanism of resistance in T.urticae.
