两种五倍子蚜虫的鉴定及倍子形态与倍蚜数量关系研究

Identification of Two Species of Gall Aphids and the Relationship between Gall Morphology and the Number of Aphids

通过观察由张家界市所产的蛋铁倍和角倍内致瘿蚜虫的玻片标本,确定了两种蚜虫分别为肚倍蚜蛋铁亚种Kaburagia rhusicola ovogallis(Tsai et Tang)和角倍蚜Schlechtendalia chinensis(Bell)。分析了角倍干湿重与倍子内蚜虫的数量关系,角倍体积与蚜虫的数量关系,初步得出结果显示:倍子内蚜虫的数量并不随五倍子的重量和体积的增大而增加。

By the observation of specimens,two species of aphid,which parasite in galls,was determined.They are Kaburagia rhusicola ovogallis（Tsai et Tang） and Schlechtendalia chinensis（Bell）.In this paper,we analyzed the relationship between the weight of gall and the number of aphids within the galls,and the relationship of the galls＇ volume and the number of aphids within the galls.At last,we came to a conclusion that the number of aphids within the gall did not grow up with the increasing of weight and volume of the galls.
