昆虫产卵分泌物的产生方式、成分及功能

产卵是昆虫生活史中的重要阶段。绝大多数昆虫产卵前后都会产生分泌物用于卵的粘着和覆盖, 这些分泌物起到保护卵及初孵幼虫的作用；有些昆虫还通过产卵分泌物对卵进行标记, 进而影响种群、个体间对现有资源的有效利用。产卵分泌物是昆虫进化过程中的一种适应, 一般具有特定的生理和生态学功能, 影响着种群数量的变化。本文阐述了不同昆虫产卵分泌物的产生方式及物理性状, 并对产卵分泌物的组成、功能、分泌器官以及产卵分泌物中微生物的研究进展进行了综述。

Deposition modes, components and functions of secretions associated with oviposition in insects

Oviposition is the important life phase in insects. Before, during or after egg-laying, most females deposit secretions near eggs. These secretions may serve as egg-adhesive substances or egg-cover substances and protect eggs and early larvae. Some insects also use the secretions as egg marking pheromones which can mediate intra- and inter-specific competition of natural resources. Considering the specific physiological and ecological functions and the influence on population densities, the deposition of secretions associated with oviposition is an evolutionary adaptation. In this article, we reviewed the deposition and physical characteristics of secretions during oviposition in various insects, and the chemical components, possible functions and excretion organs of the sectetions and the microbe species in them were also summarized.
