摘要
松突圆蚧(Hemiberlesia pitysophila)是马尾松、湿地松等松树的重要害虫。目前,广东省数百万亩松林遭受此蚧虫的侵袭,损失巨大,绿化南粤大地的计划遭到严重威胁。本项工作意图对该蚧虫的寄生蜂进行广泛的调查,为生物防治提供依据。一、寄生蜂种类及其数量分布和变动调查方法:取下松针,在解剖镜下剔除其他蚧虫,只留下松突圆蚧;然后把松针放入不透光的密闭纸盒内,在纸盒一侧装一个玻璃小指管,用灯光照射指管。
There are 12 species parasitic bees of Hemiberlesia pitysophila Takagi in 15 counties of Guangdong province.Among them,Encarsia citrina,E.amicula,and Murietta carnesi are the wider distributors, and the species of Encarsia often occupy the superiority of quantity. Up to now,all of them can not contral the scale effectively,for their parasitical rate is so low.
