This work is one of the most important bases of eliminating locusts. Studying the oogenesis of insects has important significance on demonstrating the reproductive mechanism and controlling locusts" fertility. At the same time, it"s an important means of studying the forecast of pests and the law of occurrence. It can reveal the law of ovipositing and explain the physiological basis of pests" occurrence, thus design "biorational insecticide.

研究昆虫的卵子发生对于阐明昆虫的生殖机理和控制繁殖具有重要的实践意义，是研究害虫预测预报和发生规律的一种重要手段，同时可以揭示昆虫大量产卵的规律，阐明害虫大发生的生理基础，从而设计出"生物合理的杀虫剂"，并为促进有益昆虫的大量繁殖提供理论依据。

Our reproductive system is quite complex and requires different types of nutrients in order to function properly.
