【摘要】 测定了新型杀螨剂嘧螨酯对柑橘红蜘蛛雌成螨和卵的毒杀活性,结果表明,处理后24h,嘧螨酯原药与30%嘧螨酯胶悬剂对雌成螨的LC50值分别为4.67μg/ml和5.68μg/ml,处理后48h,分别为1.50μg/ml和1.97μg/ml;处理后第10d,对卵的LC50值分别为1.56μg/ml和1.58μg/ml。30%嘧螨酯胶悬剂对柑橘红蜘蛛具有优异的防效。更多还原

【Abstract】 Bioactivity was determined for a new miticide, fluacrypyrim, against eggs and female adults of Panonychus citri. LC50s for female adults were 4.67 and 5.68μg/ml 24 h after application of technical fluacrypyrim and a 30% fluacrypyrim suspension concentrate, respectively, and were 1.50 and 1.97μg/ml, respectively, at 48 h after treatment. The LC50s of fluacrypyrim and 30% fluacrypyrim SC against eggs were 1.56 and 1.58μg/ml, respectively, 10 d after treatment. Fluacrypyrim 30% SC provided excellent control of P. citri.更多还原
