摘要:

蚜虫是一类世界性害虫,体型小、表体比大,其生长发育和暴发与环境湿度关系密切。大量研究表明,干旱胁迫对蚜虫的生活史、发育速率、迁飞特性、甚至繁殖能力等生物学特性产生直接影响;同时,干旱胁迫还会通过激活寄主植物抗虫系统,影响蚜虫天敌的生长发育、寄生行为,进而对蚜虫的发生发展产生间接效应。为应对这些不利因素,蚜虫产生了包括渗透调节、表皮碳氢化合物合成以及相关酶系统在内的一系列抗旱机制。综述了干旱胁迫对蚜虫的直接与间接影响,以及蚜虫适应干旱的相关机制,为蚜虫的综合防控策略提供思路。

Abstract:

Aphid is a worldwide pest with small body size and large surface to body ratio. Its growth, development and outbreak are closely related to environmental humidity. Numerous studies have shown that drought stress had a direct impact on the biological characteristics of aphids including life history, developmental rate, migration characteristics, and reproductive capacity; meanwhile, drought stress also activated plant defense system, and affected growth, development, and parasitic behavior of natural enemies to further affect the development of aphids. To adapt drought environment, aphids have developed a range of drought resistance mechanisms including osmoregulation, epidermal hydrocarbon synthesis, and related enzyme systems response. This paper reviews the direct and indirect effects of drought stress on aphids and the mechanisms of aphids’ adaptation to drought. It will help us to propose aphid integrated control strategies.

Key words: aphid, drought stress, growth and development, drought resistance mechanisms, pest control
