Subject(s): Online resources: In: Egyptian Journal of Agricultural Research 2015.v.93(1)B,SISummary: E xperiments were conducted in laboratory and greenhouse to assess the effects of five acaricides Abamectin , Buprofezin , Bifenazate , Chlorfenapyr and Hexythiazox against spider mite Tetranychus urticae( Koch) and its predatory mite Phytoseiulus persimilis AthiasHenriot on pepper during 2012 and 2013 seasons. Data showed that the highest general mean reduction percentages of two seasons against T. urticae were obtained by Abamectin and Chlorfenapyr , while Bifenazate and Hexythiazox were as equale as the lowest effects .On the other hand, there were significant differences in T. urticae population on pepper between treatments and check after spraying . The difference between the compounds may be due to their mode of action. Results indicate that Hexythiazox , Bifenazate and Buprofezin were very less toxic to the predatory mite, P. persimilis adult females than those of spider mite, T. urticae in greenhouse conditions, confirmed the results obtained to a large extent in the laboratory experiments.
