EFFECT OF CERTAIN PESTICIDES ON SOME PHYTOPHAGOUS AND PREDACEOUS MITES ASSOCIATED WITH CITRUS TREES

Three field experiments were conducted to evaluate the effec‌tiveness of Fenpyroximate, Flufenoxuron, Abamectine, super Shokrona and Shokrona oils against Eutetranychus orientalis (Klein), Brevipalpus californicus (Banks), Phyllocoptruta oleivora Ashmead and their side ef‌fect on the predaceous mite, Euseius scutalis Athias-lienriot on Navel or‌ange citrus trees . The first experiment was conducted at Wasta station, Beni-Suef Governorate to estimate the effect of the tested compounds against E. orientaiis, the second experiment was performed at Kafr‌Mansour village, Qualubia Governorate to control the flat mite B. califor‌nicus and the third experiment was conducted at Desones District, Da‌manhour city , Behera Governorate to control Ph. oleivora _ The results revealed that fenpyroximate was the most effective compound against E. orientalis and B. califomicus followed by Flufenoxuron and super Shok‌rona oil. Shokrona oil was the least effective . With regard to the effect on the predatory mite E. scutalis , Flufenoxuron and fenpyrosximate showed the highest effect, while Super Shokrona oil was of intermediate effect. The lowest reduction in the predatory mite population was with Shokrona oil. Fenpyroximate and Abamectin were the most effective com-pounds against Ph. oleivora. Flufenoxuron, Super Shokrona and Shokrona oil came next, respectively. Percentages of rusty fruits in trees treated with Fenpyroximate and Abamectin were less than in any other treatment.
