الفعالية الاولية لبعض المبيدات علي افراد الاكاروس الاحمر ذي البقعتين Tetranychus urticae Koch (Acari:Tetranychidae) المقاومة للدايمثوات

In order to search for modern coumpounds to control the increase and development red mites which resistant to pesticides and in order to limit damages and costs together with amount of pesticides many experiments were carried out to determine primary effects of many pesticides of many pesticides (Abamectin, Azocyclotin, Biphenthrin, Flufenoxuron, Carbosulfan and Bromopropylate) on female of two spotted red mites (Tetranychus urticae Koch) which resistant to Dimethoat (adults and deutonymphe). Results showed ,by using leaf disk way of commen beans Phaseolus vulgaris L .and through dipping the shifts in solution of pesticides, the two compounds Abamectin and Azocyclotun had high mortality which was 100 , 89.12% respectively in resistant strain and the mortality reached in deutonymphes in the same strain to 100, 92.92 % for the two coumpounds respectively , there were no significant differences with susceptible strain and the same with control Bromopropylate. Biphenthrin had significant differences between two strains and its results were 76.41 and 83.63 % respectively on adults and deutonymphes. Flufenoxuron and carbosulfan had significant differences between the two strains and mortality for the first was better on deutonymphe which was 39.34%. Carbosulfan had mortality 20% on resistant individuals for the two treated stages.So ,this compounds are not affective in control programs. The results showed possibility of using Abamectin ,Biphenthrin and Azocyclotin to control resistant strain to organophosphates as primary procedure which must improve in carring out many research .
