摘　　要：为提高稻螟蛉的防治效果,促进减药增收,以绥粳18为试验材料,以200亿CFU·g^-1菌粉球孢白僵菌(水谷欣)、20%氯虫苯甲酰胺悬浮剂(康宽)、34%乙多·甲氧虫(斯品诺)、二化螟性诱剂为供试药剂,研究不同药剂对水田稻螟蛉的防治效果。结果表明:在7月初水稻分蘖末期叶面喷施360 mL·hm^-2斯品诺能够有效防控稻螟蛉的危害,水稻平均增产3.86%。同时,其对二化螟也具有良好防效,是绿色水稻生产中防治稻螟蛉和水稻二化螟的理想药剂。In order to improve the control effect of Naranga aenescens Moore,and reduce pesticide,increase income,Suijing 18 was used as the experimental material,and 20 billion CFU·g^-1 of Beauveria bassiana(Shuiguxin),20%Chlorantraniliprole SC(Coragen),spinetoram+methoxyfenozide 34%SC and sex attractant of Chilo suppressalis were used as the experimental agents to study the control effect of different agents on Naranga aenescens Moore.The results showed that spraying 360 mL·hm^-2 spinetoram+methoxyfenozide on the leaves at Late tillering stage in early July could effectively prevent and control the damage of Naranga aenescens Moore,and the average yield of rice increased by 3.86%.At the same time,it has good control effect on the Chilo suppressalis,and was an ideal agent for controlling the Naranga aenescens Moore and Chilo suppressalis in the green rice production.
