摘要
通过田间调查和室内饲养得出,在昆明地区糠片盾蚧(ParlatoriapergandiiComstock)的寄生蜂有7种,即桑盾蚧黄蚜小蜂(Aphytisproclia(Walker))、夏威夷蚧食蚧蚜小蜂(CoccophagushawaiiensisTimberlake)、桑盾蚧恩蚜小蜂(Encarsiaberlesei(Howard))、瘦柄花翅蚜小蜂(Mariettacarnesi(Howard))、扁角跳小蜂(Anicetussp ),彼菲质绒跳小蜂(TeleterebratuspeversusCompere＆Zinna)和柯氏花翅跳小蜂(MicroterysclauseniCompere),隶属于膜翅目的蚜小蜂科和跳小蜂科。自然条件下寄生蜂对糠片盾蚧的平均寄生率为12 6%。树冠上部的寄生率高于中部和下部;树冠西面、北面的寄生率高于东面和南面。糠片盾蚧寄生蜂的种群空间分布用Taylor幂法则和Iwao的m -m回归分析法进行分析,得出的结果均一致,即糠片盾蚧寄生蜂在苹果园中的种群空间分布均为均匀分布。
Parasitic wasps of Parlatoria pergandii (Comstock)were identified as Aphytis proclia(Walker),Coccophagus hawaiiensis Timberlake, Encarsia berlesei(Howard),Marietta carnesi(Howard),Anicetus sp.,Teleterebratus perversus Compere&Zinna,and Microterys clauseni Compere through field and laboratory survey in Kunming,The pest was naturally parasitized by 12.6?%in average.The parasitization of the pest was higher in the upper of canopy of hosts than that of the mid-low,and the Western and the Northern than the Eastern and the Southern.Analysis by using Iwao's and Taylor's law showed that spatial distribution pattern of the Parasitic wasps was equality distribution in apple garden.
