摘要
油松(Pinus tabuliformis)是内蒙古重要的造林树种,油松大蚜(Cinaraformosana)是危害油松的害虫之一,利用天敌昆虫来防治油松大蚜是重要的有效途径,因此,调查油松大蚜的天敌昆虫是非常必要的。在和林格尔县和武川县,对油松大蚜及其主要天敌的虫口密度和天敌种类进行了调查研究,室内饲养测定了天敌昆虫日均捕食量。结果表明,样地内油松大蚜的主要天敌有异色瓢虫(Leis axyridis)、七星瓢虫(Coccinellaseptempunctata)、双钩齐褐蛉(Kimminsiabihamita Yang)、伪郭公虫(Sasajiscymnustsugae)等6种,室内饲养异色瓢虫日均捕食量为23.8头,双钩齐褐蛉幼虫日均捕食量为15.1头,伪郭公虫日均捕食量为11.9头。
Pinus tabuliformis is an important afforestation tree species in Inner Mongolia,and Cinaraformosana is one of its harmful pests.It is an important and effective way to control Cinaraformosana by using natural enemies.Therefore,it is very necessary to investigate its natural enemies.In Helinger County and Wuchuan County,the population density and natural enemy species of Cinaraformosana and its main natural enemies were investigated,and the average daily predation of its natural enemy insects was measured by indoor feeding.The results showed that the main natural enemies of Cinaraformosana in the sample plots were 6 species,such as Leis axyridis,Coccinellaseptempunctata,Kimminsiabihamita Yang and Sasajiscymnustsugae.The average daily predation amount of Leis axyridis,Kimminsiabihamita Yang,and Sasajiscymnustsugae was 23.8,15.1 and 11.9 respectively.
