Abstract

The efficacy of tetradifon at 80 and 160ppm was very high on eggs, larvae and nymphs of Tetranychus arabicus Attiah. Tetradifon caused prolongation in duration of active and quiescent stages followed by death. Treated deutonymphs at 80ppm were less affected and 45.71% individuals completed their life-cycle. Tetradifon greatly affected the lon­gevity and fecundity of T. arabicus adult female.
