The objective of this study was conducted to determine the efficacy of five acaricides; Abamectin, Emamectin benzpate, Acequinocyl, Chlorfenapyr and Hexythiazox against Tetranychus urticae and its natural enemies, Phytoseiulus persimilis and Stethorus gilvifrons. The tested acaricides were arranged in a descending order of speed of action against T. urticae as follows: Abamectin, Emamectin benzoate, Acequinocyl, Chlorfenapyr and Hexythiazox with LT so; 1,77, 2.85, 3.16, 3.94and 4.55 days, however, the corresponding speed action index were 100.00, 62.11, 56.01, 44.92 and 38.90%, respectively. Concerning P. persimilis, Abamectin was the slowest Speed of action compared with other tested acaricides (LT5o= 4.31 days) followed by Acequinocyl, Emamectin benzoate, Chlorfenapyr and Hexythiazox with LT5o; 2.90, 1.78, 1.38 and 1.03 days and the corresponding speed action index of 23.90, 35.52, 57.87, 74.64 and 100.00 %, respectively.
Summary in Arabic.
