摘要
对贵阳地区的烟仓害虫天敌种类进行了调查.结果表明,其天敌共有11种,隶属3纲、7目、10科;优势种天敌为麦蛾柔茧蜂、米象金小蜂.麦蛾柔茧蜂完成一代夏季为9～13d,秋季为13～18d,一年发生世代数可达10代以上;成虫寿命12～17d.将采集的烟草粉斑螟幼虫于室内饲养,麦蛾柔茧蜂的出蜂率为46.0%;在烟仓的墙壁、过道和烟包表层,麦蛾柔茧蜂对烟草粉斑螟的平均寄生率达61.0%.米象金小蜂完成一代需30～33d,发生世代数3代;成虫寿命为10～15d.在烟仓,该蜂对烟草甲幼虫和蛹的寄生率分别为24.53%～33.70%、42.59%～61.64%.米象金小蜂对寄主烟草甲的跟随现象明显.
Investigation of natural enemies in tobacco storage showed that there are 11 species in 3 class, 7 order, 10 family. The predominant species are Habrobracon hebetor and Lariophagus distinguendes. H. hebetor completes a generation within 9 - 13 days in the summer and 13 - 18 days in the autumn, and occurs more than 10 generations in a year. Adult longevity of H. hebetor is 12 - 17 days. Parasitism rate of Ephestia elutella larvae collected on the wall, corridor and package surface in tobacco storage reached 61%. L. distinguendus completes a generation within 30 - 33 days and occurs 3 generations in a year, with adult longevity of 10 - 15 days. Parasitism rates of larvae and pupae of Lasioderma serricorne by L. distinguendus in tobacco storage were 24.5% - 33.7% and 42.6% - 61.6%. Therefore, the protection and utilize of natural enemies are very important during tobacco storage.
