摘要:

采用样方内各种捕食天敌数量与其捕食量引起辽宁松干蚧Matsucoccus liaoningensis Tang1)死亡数的调查统计法、K-值图解分析法,研究了辽宁松干蚧捕食天敌的作用。发现捕食天敌对雌成虫有较大的捕食作用,对卵囊的作用较小。在瓢虫类、草蛉类、螨类、蝽类、蚂蚁类和蜘蛛类捕食天敌中,瓢虫类的捕食作用最大,其次是蚂蚁类。瓢虫主要种类是异色瓢虫、刻点艳瓢虫、蒙古光瓢虫;蚂蚁主要有扁平虹臭蚁和双齿多刺蚁。1).原误认为是Matsucoccus matsurae(Kuwana)。

Abstract:

The research was carried out by investigating number of predators and predation capabilities along with mortalities of the pine bast scale (Matsucoccus liaoningensis Tang) inside sampling plot, and by applying the K-value graphic analysis method.It was found that the predation happened mainly on female imago, but seldom on egg sac.Among the predators, such as ladybug, lacewing, mite, stinkbug, ant and spider, the predation capability of ladybug ranks the highest, and the ant the second.The main predator species are ladbug Harmonia axyridis Pallas, Sticholotis punctata Crotch, Exochomus mongol Barovsky; ant Iridomyrmex anceps Roger, and Polyrhachis dives Smith.
