东乡伊蚊自殖株和非自殖株卵黄发生动态的比较研究

Comparative Study of the Vitellogenesis in Autogenous and Anautogenous Strains of Aedes togoi

以实验室分离所得的东乡伊蚊自殖株和非自殖株为材料,用组织化学法、免疫组织化学法对两株蚊虫卵黄发生的动态进行了比较研究。结果发现,卵黄发生规律在同种不同生理株蚊虫各有特征,自殖株卵黄原蛋白合成在成蚊羽化后不久即启动,发生过程循序渐进,直至卵母细胞吸收沉积卵黄蛋自发育成熟;非自殖株卵黄原蛋白的合成则必须在吸血之后才开始,卵黄发生过程在吸血前有明显的休止期。结果还显示,两株蚊虫卵黄原蛋白的合成能力也有差异。

This report deals with the comparative study on the vitellogenesis in autogenous and anautogenous strains of Aedes togoi. Histochemical and immunohistochemical methods were used. It was found that rule of vitellogenesis is characteristic in different strains within the same species. Synthesis of vitellogenin in autogenous strain begins as soon as post-emergence and the process goes on continuously, up to the oocytes to take in vitellin for maturation. Vitellogenin synthesis in anautogenous strain starts after blood meal, and there is an apparent testing stage before blood feeding. The capacity of vitellogenin synthesis is also different between two strains.
