EVALUATION AND APPRAISAL OF SOME PREDATORY MITES OF PRINCIPAL ACARINE PESTS ON VEGETABLE CROPS

Abstract
Biolo ical aspects of the predacious mites, Amblyseius cydnodactylon and Cydnoseius negevi were determined. Effects of the prey stage of Tetranychus urticae and prey species including Aceria ficus,Eriophyes dioscoridis, Bemisia tabaci and Thrips tabaci were investigated.
Ecological studies included effects of leaf surfaces, nymph densities of T.urticae in absence or presence of B.tabaci nymphs, temper atures and relative humidities on the survival, reproduction and consumption rates.
Toxicological studies showed that malathion and dimethoate were severely toxic to A.cydnodactylon and C.negevi, respectively. A malathion-resistant strain of A.cydnodactylon was induced, although the reproduction decreased after
8 selections.
