The efficiency of different groups of pesticides to suppress the population of the two spotted spider mite, Tetranychus urticae Koch on water melon plants was studied. The pesticides include three biochemical compounds: Yurmak 1.8%
EC (Abamectin), Veto 5% EC (Abamectin), and Biofly 30x103 WP (Beauvaria bassiana); three acaricides: Ortus 5% SC (Fenpyroximate), Acarots 5% EW (Fenpyroximate) and Prince 10% EC (Hexythiazox) and two mixture compounds: Nest 20% SC (Abamectin2o/o + Spirodiclofen 18 %) afi Perfect 12%EW (Abamectin 2% + Chlorfenapyr 10% ). They were applied for one time to control T. urticae infesting water melon plants during the experimental period. The different acaricides formulations were effective to control T. urticae for two weeks after application. Abamectin (biochemical) was more effective in reducing TSSM population than true spiders and revealed less effect on associated predators; while Hexythiazox was the most harmful acaricide in reducing true spider populations. The results will be helpful to develop IPM Programs with true spiders in agricultural crops.
