摘　　要：通过田间药效试验评价34%乙多·甲氧虫悬浮剂对水稻3代二化螟的田间防治效果,并通过数学模型分析进一步为田间应用提供试验和理论依据。34%乙多·甲氧虫悬浮剂在供试有效成分用量120,132,162 g/hm^2下对水稻3代二化螟的平均防效为71.4%~82.0%。数学模型分析结果表明,34%乙多·甲氧虫悬浮剂对3代二化螟防效为80%时,所需理论用量在150 g/hm^2以上。Field efficacy trials were conducted to evaluate the performance of spinetoram+methoxyfenozide 34%SC against the third generation of Chilo suppressalis in rice fields.Mathematical model analysis was employed to understand the potential rate of spinetoram+methoxyfenozide 34%SC to provide the theoretical basis.Spinetoram+methoxyfenozide 34%SC at application rates of 120,132,162 g/hm2 provided 71.4%-82.0%control effects on the third generation of Chilo suppressalis.The mathematical model analysis indicated that to achieve average 80.0%control effect,the theoretical rate of spineotram+methoxyfenozide 34%SC would be 150 g/hm2.
