[Method] By field trials, the effects of six kinds of commonly used pesticides on P. regalis were determined. ln addition, different agri-cultural measures were employed to integrate control technologies. [Result] At the early occurrence stage of P. regalis, spraying 7.5g/hm2 5% emamectin benzoate EC, 13.5 g/hm2 2% avermectin EC and 25 g/hm2 2.5% lambda-cyhalothrin EC can ef-fectively control P. regalis. [Conclusion] This study provided reference for the pre-vention and control of P. regalis.展开更多
