摘　　要：为探讨性诱剂对玉米二点委夜蛾的诱杀效果,2012年在辛集市马兰农场,分别利用二点委夜蛾性诱剂和佳多虫情测报灯,进行了二点委夜蛾田间诱杀试验,并分析了性诱剂的可持续使用时间;并利用2012年5月1日～8月31日辛集市气象资料,分析了前5日气象条件对二点委夜蛾发生数量的影响。结果表明:利用性诱剂诱杀二点委夜蛾雄蛾,不仅诱蛾数量较大、方法简便、数据完整,能够准确描述二点委夜蛾的发生动态,而且诱蛾成本低廉,可以用于预测测报和生产防治;1只性诱剂可持续使用120 d;性诱剂诱蛾数量与前5日气象条件关系密切,气温偏高、湿度偏小、降水偏少时有利于二点委夜蛾蛹的羽化,诱蛾量增加。In order to research the trapping effect of sex attractant to corn A. lepigone, the field trapping experiment of A. lepigone was tested on Malan farm of Xinji City in 2012 by sex attractant of A. lepigone and automatic pest forecast lamp, and the sustainable use time of sex attractant was analyzed. At the same time, the effect of meteorological conditions of previous five days on the quantity of A. lepigone was analyzed using the meteorological data of Xinji City from May 1 to August 31 in 2012. The results showed that one sex attractant of A. lepigone male moths for 120 d had the virtues of effectively reduce adult, simple use, full data to accurate description the occurrence of dynamic for A. lepigone and low cost to used for predict and monitor to field prevention. The sex attractantd traped adults closely related to meteorological conditions of previous five days, and high temperature, low humidity and low rainfall were favorable for pupa emergence and adults increase.
