摘　　要：近年来,榆三节叶蜂发生严重,大大降低了榆树的园林景观效果,该文开展了榆三节叶蜂发生规律观测及防治试验。研究发现:榆三节叶蜂在沧州地区1a发生2代,以老熟幼虫在土中结丝质茧变为预蛹越冬。以幼虫取食各种榆树叶片危害,危害期集中在6月下旬至7月中旬、8月中旬至9月上旬。在防治榆三节叶蜂幼虫时,宜采用25%灭幼脲悬浮剂1500~2000倍液、苏云金杆菌乳剂1500~2000倍液、白僵菌可湿性粉剂800~1000倍液,4.5%高效氯氰菊酯乳油1000~1500倍液喷雾适用于虫龄较大或大发生时使用。防治效果均可达到90%以上。In this paper,the occurrence regularity observation and control experiment of Arge captiva Smith were carried out.The results showed that there were two generations of Arge captiva Smith in one year in Cangzhou area,andthe mature larvae formed silk cocoon in the soil to transform into pre-pupae and overwintered.The larvae of Arge captiva Smith fed on various elm leaves.The damage period was mainly from late June to midJuly and from mid-August to early September.In the control larva of Arge captiva Smith,it was suggested to use25%Chlorbenzuron SC1500~2000 times liquid,Bacillus thuringiensis emulsion 1500~2000 times liquid,Beauveria WP 800~1000 times liquid,4.5%Beta cypermethrin EC 1000~1500 times liquid.
