摘要
通过系统调查分析了深点食螨瓢虫(Stethorus punctillumWeise)、中华草蛉(Chrysopa sinicaTjeder)和塔六点蓟马(Scolothrips takahashii Prisener)这3种截形叶螨(Tetranychus truncatus Ehara)的主要天敌对截形叶螨的控制作用。采用Holling的圆盘方程拟合,经卡方检验法,对截形叶螨的捕食功能进行分析。结果表明,对不同密度和不同螨态下截形叶螨的捕食功能反应分别符合HollingⅡ型。深点食螨瓢虫、中华草蛉和塔六点蓟马成虫对截形叶螨卵和成若螨日最大捕食量分别为42.24粒和36.64头;31.82粒和25.05头;39.17粒和31.40头,这3种天敌成虫对截形叶螨卵的捕食量均大于其成若螨。3种天敌各自在不同情况下对截形叶螨的控制作用,表明其具有重要的保护利用价值。
The major natural enemies of Stethorus punctillum Weise,Chrysopa sinica Tjeder and Scolothrips takahashii Prisener had controlled Tetranychus truncatus Ehara,which were systematically analyzed in this paper.Using Holling disc equation fitting and the chi-square test,the predacious performance of Tetranychus truncatus Ehara were analyzed.The result showed that under different densities and mite state,the responce of the predacious performance of Tetranychus truncatus Ehara were coincident with HollingⅡtype respectively.The daily maximum predacious number of adult of Stethorus punctillum Weise,Chrysopa sinica Tjeder and Scolothrips takahashii Prisene to Tetranychus truncatus Ehara eggs and adult nymph were 42.24 head and 36.64head;31.82 head and 25.05head;39.17 head and 31.40 head,the predacious number of these three natual enemies abults to Tetranychus truncatus Ehara eggs were greater than that of adult nymph.The controlling role conducted by these three natual enemies in different conditions on Tetranychus truncatus Ehara showed that they had important protective value in the practical utilization.
