膜翅目昆虫杜氏腺形态结构、内分泌物与功能的研究进展

杜氏腺为膜翅目雌性昆虫生殖器官中的一外分泌腺体，外形呈囊腔状，内含丰富的油状分泌物。其内分泌物主要为饱和与不饱和烃类化合物，有着辅助产卵、释放信息素及作幼虫食物等多方面的功能。本文对杜氏腺的形态结构、内分泌物合成途径、化学组分及其生理和生态学功能进行了综述。

Research progress on morphology, secretion and function of Dufour gland in Hymenoptera

Dufour gland is an abdominal exocrine gland associated to the reproductive apparatus in all aculeate hymenopteran females. It is morphologically similar and of tubular shape with numerous oily secrete contents. Most of the secretions are blends of saturated and unsaturated hydrocarbons. A broad array of these chemicals were involved in a number of physiological and semiochemical functions, such as assisting reproduction as lubricant to fast the egg laid, playing intricate roles in communication and defense as pheromone, serving as larval food, etc. In this article, the morphology and chemical composition of Dufour gland were introduced, the ways that the secretions are synthesized were discussed, and the functions of the secretions were reviewed.
