趋光是众多夜行性昆虫的主要行为特征之一.研究表明:许多夜行性昆虫的趋光存在明显的性别差异现象,而这种差异受多种因素的影响.本文从雌雄成虫飞行能力差异导致其飞行距离与高度的不同、雌雄成虫复眼结构差异导致其对光源反应不同,以及雌雄成虫对光源和环境刺激的敏感性不同等方面综述了导致昆虫趋光性别差异的因素,并探讨了昆虫趋光性别差异的应用及今后研究方向.
Flight-to-light is one of the major behaviors of nocturnal insects.Previous studies have demonstrated that many nocturnal insect species have noticeable sexual difference in the behavior of flight-to-light,and many factors may contribute to this kind of difference.This paper reviewed the sexual difference of insect phototactic behavior in terms of the difference in flying distance and height between female and male adults due to their different flying capability,the distinct difference in the response to light resource due to the different structure of compound eyes between female and male adults,and the difference in the sensitivity to the light source and other environmental factors between female and male adults.The applied aspects and future research directions of the sexual difference of nocturnal insect phototactic behavior were also discussed.
