INTEGRATED MITE MANAGEMENT
Rabab Abd El-kawy Mohamed Amin Hammad;
Abstract
In preparation of the integrated Inite management program,
Laboratory experiments were carried out to evaluate the toxic effect of five compounds (three acaricides; Abamectin, Fenpyroximate and Etoxazole; one pyrethroid; Cypennethrin and one mineral oil Supennasrona) against the egg and adult females of the two spotted spider mite Tetranychus urticae (Koch) and adult females of predatory mite Amblyseius gossipi (El-Badry) on three different host plants (castor bean, green beans and tomato) using leaf-disc dip technique. The side effect of mentioned compounds on some biological aspects of two species of miteswere also evaluated.
Abamectin has a special position in integrated mite management mite control programs. Cypennethrin was the most effective compom1d tested on egg deposition of on T urticae castor bean, while on the other two hosts occupies the next position after Fenpyroximate. Also, Cypennethrin was highly toxic compound that caused the highest decrease in egg hatchability especially on castor bean and green beans, but on tomato it occupies the next position after Fenpyroximate.
According to the narure of the chemical the prey egg consmnption by the predator changed depending on time elapsed between egg contamination by chemical and egg introduction to the predator, also consequently the predator egg production.
