论文部分内容阅读
昆虫的体色由色素色和结构色混合形成,而体壁中色素的形成和分布受多种内外因子的影响。在一些昆虫中,环境温度已被证实为主要外界因子。文献中也曾有过关于蚜茧蜂(Hymenoptera:Aphidiidae)成虫体色的形成受温度影响的报导,但比较粗略,也未引起人们适当的重视,从而在蚜茧蜂的分类和鉴定中带来一些混乱,妨碍了蚜茧蜂的研究和蚜虫的生物防治工作。本项工作就温度对蚜茧蜂成虫体色形成的影响做了较系统的观察。整个工作分两部分。第一部分是详细观察斯氏蚜茧蜂(Aphidius smithi)体壁颜色形成
The body color of insects is formed by the combination of pigment color and structural color, while the formation and distribution of pigment in the body wall are affected by many internal and external factors. In some insects, the ambient temperature has been confirmed as the main external factor. There have also been reports in the literature on the temperature-dependent body color formation of the adults of Hymenoptera: Aphidiidae, but they have not been given due attention and have been brought into the classification and identification of Aphidius bee Some confusion, hinder the aphid bee research and aphids biological control efforts. This work made a more systematic observation of the effect of temperature on the body color formation of adults. The whole job is divided into two parts. The first part is a detailed observation of body color formation of Aphidius smithi
