In vitro and in vivo Efficacy of Some Acaricides and Two Fungi of Trichoderma spp. on Some Biological Aspects of Tetranychus urticae Koch and the Predaceous Mite, Phytoseiulus persimilis Athias- Henriot on Cucumber Plants

Abstract

Koch (Acari: Tetranychidae) is a major pest mite infesting vegetables and horticultural ornamental and agronomic crops in Egypt. In biological control strategies, natural enemies were applied to maintain TSSM population below the level where damage occurs for an extended period of time besides utilizing acaricides in a critical situation as a quick practice to avoid deleterious TSSM damage. This study evaluated the potential of acaricides (Abamectin, Chlorfenapyr, Fenpyroximate and Hexythiazox ) and the pathogenicity of native species of
