抚顺市松阿扁叶蜂防治技术研究初报

根据松阿扁叶蜂的生物学、生态学特性，在松阿扁叶蜂成虫和幼虫期应用化学药剂、释放赤眼蜂、人工破坏预蛹及老熟幼虫越冬环境等措施，进行了对比防治试验，结果表明：人工破坏松阿扁叶蜂老熟幼虫和预蛹的栖息环境，杀虫效果可达85％以上；地面施用1．8％阿维菌素乳油8000倍液、1．2％苦参烟碱1000倍液杀幼虫效果均为100％；阿维菌素烟剂、苦参烟碱烟剂(含乳油)杀灭成虫．效果均达93％以上。

Control techniques against Acantholyda posticalis in Fushun

According to the bionomics and ecological characteristics of Acantholyda posticalis,the control experiments were made in the adult and larval periods. Measures such as application of chemical pesticides, release of Trichogramma dendrolim and artificial destroy of the hibernacula of the matured larva and prepupa were used. The result showed that artificial destroy of the hibernacula could kill 85%of the pest. The application of 1.8% abamectin EC 8 000 times and 1.2% matrine 1 000 times could kill 100% of the larvae while the smoke generator of abamectin and matrine could kill 93% of the adults.
