不同品种及性别家蚕感染菜粉蝶微孢子虫差异性分析

Difference Analysis of Different Varieties and Genders of Silkworm Infected by Microsporidium Isolated from Pieris rapae L.

为了解不同品种及不同性别家蚕感染菜粉蝶微孢子虫的差异性,利用菜粉蝶微孢子虫对9个不同的家蚕品种(8个原种、1个杂交种)进行感染性添食试验,添食菜粉蝶微孢子的浓度和数量均相同。结果表明,家蚕各品种之间感染菜粉蝶微孢子虫的情况存在明显的差异,秋华最容易被微孢子虫感染,皓月感染力最低。同时,对不同家蚕品种雌雄蛾感染率进行调查,发现家蚕雌雄蛾之间感染菜粉蝶微孢子虫的差异并不显著。

In order to explore the difference of different varieties and genders of silkworm infected by microsporidium isolated from Pieris rapae L.,9 silkworm varieties（8 original seeds,1 hybrid specie） were fed with mulberry leaves infected by the same concentration and number of microsporidium isolated from Pieris rapae L. The results of the experiment showed that,there was obviously difference among silkworm varieties infected by the microsporidium isolated from Pieris rapae L. The ＂Qiuhua＂ was the most easily infected species by the microsporidium,and the ＂Haoyue＂ species have the lowest infection rate.But there were no significant difference in the infection rate between genders of silkworm infected by this microsporidium.
