蜱类卵黄发生研究进展

Advances in tick vitellogenesis

蜱是一类特殊的节肢动物,有关其生殖生理的研究远远落后于昆虫。卵黄发生直接影响蜱类的繁殖力,一直是蜱类生理学一个十分活跃的研究领域。目前,对蜱类卵黄发生的研究主要包括卵黄蛋白的纯化与鉴定,卵黄原蛋白的合成与调控,卵母细胞对卵黄原蛋白的摄取以及转变为卵黄蛋白的分子过程。蜱类卵黄发生受激素调控,激素的作用与作用激素的种类在硬蜱和软蜱中表现出较大差别。对蜱类卵黄发生了解得尚少,在许多方面需深入研究。

Ticks are a specific group of arthropods. The knowledge of reproductive physiology in ticks is very limited as compared to insects. Vitellogenesis directly influences tick reproductive ability, and is always a very active research field in tick physiology. At present, the research mainly concentrates on vitellin purification and characterization, vitellogenin synthesis and hormonal regulation, vitellogenin absorption and processing. Vitellogenesis is regulated by hormones. There are obvious differences between hard ticks and soft ticks in hormonal effects and sorts. The knowledge of tick vitellogenesis is preliminary, and further research should be made in many aspects.
