蝗虫微孢子虫对蝗虫脂肪含量的影响

用东亚飞蝗Locusta migratoria manilensis作为活体寄主，将4龄蝗蝻接种蝗虫微孢子虫Nosema locustae后，对虫体总脂含量和血淋巴中的甘油脂含量、脂肪酶活力进行了测定，结果表明：蝗虫微孢子虫的寄生可导致东亚飞蝗虫体总脂含量和血淋巴甘油酯含量大幅度下降及血淋巴脂肪酶活力大幅度上升。根据病虫生理指标提出了一种新的病级鉴定方法。

Effect of Nosema locustae on the content of fat inLocusta migratoria manilensis

In this study the authors using Nosema locustae as a parasite on Locusta migratoria manilensis, measured the content of glyceride and lipase activity in haemolymph and the total fat of the locust infested. The results manifest that N. locustae can cause the content of glyceride in haemolymph and the total fat of L. migratoria manilensis decline rapidly and the lipase activity in haemolymph rise rapidly. A new identifying method of grade of disease according to the physiological guideline is suggested.
