有瓣蝇类触角感受器形态与功能研究进展

Morphology and functional implication of antennal sensilla in Calyptratae

有瓣蝇类隶属于昆虫纲双翅目,其物种多样性高,适应能力强,生态类型丰富,与人类关系密切,是开展昆虫适应演化研究的理想类群。触角是有瓣蝇类最重要的嗅觉感受器官,在其精准寻找食源,高效完成交配、产卵等生活史环节中都起着获取外界信息的关键作用。目前已有大量对于有瓣蝇类触角感受器的研究,但这些研究对触角感受器形态名词的使用存在诸多差异、混乱和歧义,使得不同研究间难以相互参考。本文统一了之前研究中有瓣蝇类触角上常见的各类感受结构的不同名词;并结合其它昆虫类群的相关研究,综述了各类感受器在形态和功能方面的研究进展;探讨了该领域中尚待解决的问题。

Calyptratae is a phylogenetic group in Diptera with extremely high diversity,strong adaptability,wide distribution,high rich ecological types,and close relationship with human,this group has become an ideal model for insect adaptive evolution studies.Antennae are crucial parts of insect chemosensory system,playing important roles of receiving cues from the environment in the process of their critical life history stages,such as accurately seeking for food sources,locating mates and oviposition places.Despite the large number of studies on the antennal sensilla of Calyptratae,the majority of them are inconsistent with the morphological terminologies,making it difficult for comparative analyses.This review unified the terminology applied to the classification of common antennal sensilla types,discussed progresses on their morphology and function by summarizing and comparing with relevant researches,and proposed on-going the challenges and controversies in this field.
