摘　　要：为比较20%环丙氟虫胺悬浮剂对二化螟的防控效果,提升水稻螟害防控能力,于2022年在杂交水稻上开展螟害防效试验。结果表明,在杂交水稻二化螟危害初期或枯鞘初现期667 m^(2)施用2次20%环丙氟虫胺悬浮剂15或20 mL,对二化螟全代防控效果可达80.92%和97.65%,其持效期可达20~30 d;但其对二化螟幼虫的速效性不强。因此,在水稻二化螟防治过程中应遵循“打早、打小”的原则,提倡在卵孵高峰期作2次(间期10 d)长效防控。In order to compare the control effect of 20%cyproflanilide suspension on the Chilo suppressalis Walker and improve the prevention and control ability in rice,a Chilo suppressalis Walker control effect test was carried out on hybrid rice in 2022.The results showed that the twice application of 15 or 20 mL of 20%cyproflanilide suspension at 667 m^(2) in the early stage of Chilo suppressalis Walker damage or the initial stage of wilting sheath in hybrid rice could have a control effect of 80.92%and 97.65%on the whole generation of Chilo suppressalis Walker,and its effective period could reach 20-30 days.However,its fast-acting effect on the larvae of Chilo suppressalis Walker was not strong.Therefore,in the control process of Chilo suppressalis Walker,the principle of“preventing as early and young as possible”should be followed,and long-term prevention and control should be carried out twice(interval 10 days)during the peak period of egg incubation.
