摘　　要：舞毒蛾危害通辽市科尔沁杨柳榆等阔叶树种,通过野外踏查结合系统观测的方式摸清了舞毒蛾在科尔沁区的生物学特性和发生等级判断方法。针对不同龄期幼虫进行了防治试验,结果表明:1月末~2月末进行摘卵破卵防治;5月1日~15日对初孵幼虫采用1.2%烟碱·苦参碱乳油1000倍液喷雾防治;6月中旬前对2~3龄幼虫施放15%异丙威烟剂防治效果好。The armyworm poses a threat to broad-leaved tree species such as poplar,willow,and elm in Tongliao City.Through field investigations and systematic observations,the author has investigated the biological characteristics and occurrence level judgment methods of armyworms in the Horqin area.Control experiments were conducted on different instar larvae,and the results showed that egg picking and breaking prevention were carried out from the end of January to the end of February;From May 1 to 15,the newly hatched larvae were treated with 1.2%nicotine and matrine emulsion 1000 times spray;The application of 15%isopropyl carb smoke agent to 2-3 instar larvae before mid June has a good control effect.
