摘要：[目的]光肩星天牛柄腹茧蜂(Spathius anoplophorae Yang)是新发现的寄生光肩星天牛低龄幼虫的外寄生蜂,对光肩星天牛有很好的寄生控制效果,但是该虫的寄主嗅觉信号识别机制尚不明确。为了明确光肩星天牛柄腹茧蜂的触角感受器的种类和形态。[方法]本文通过扫描电镜对光肩星天牛柄腹茧蜂雌、雄成虫的触角和感受器超微结构进行了观察,并进一步分析不同性别成虫触角感受器的分布规律、大小及数量。[结果]光肩星天牛柄腹茧蜂触角呈丝状,雌蜂由1个柄节、1个梗节和33个鞭节亚节组成,雄蜂由1个柄节、1个梗节和31个鞭节亚节组成。在光肩星天牛柄腹茧蜂触角上共发现了8种感器,分别包括B?hm鬃毛、刺形感受器、毛形感受器、板形感受器、腔锥形感受器、栓锥形感受器、鳞形感受器和表皮孔。[结论]发现雌、雄间的触角感受器分布位置无明显不同,但在触角整体及各节的长度和宽度,感受器类型、长度、宽度和数量上存在显著差异。结果为后续对该寄生蜂的化学通讯和嗅觉行为机制研究奠定基础。
[Objective]Spathius anoplophorae(Hymenoptera:Braconidae)is an important ectoparasitic wasp that parasitizes the Asian longhorned beetle during its early larval stage.It exhibits excellent parasitic control effects on the beetle,but the mechanisms of olfactory signal recognition in this parasitoid remain unclear.This study aims to examine the variety and morphology of the antennal sensilla of S.anoplophorae.[Method]Scanning electron microscopy was used to observe the ultrastructure of the antennae and sensilla in both male and female adult parasitoids.The distribution,size,and number of sensilla on the antennae of females and males were analyzed.[Result]The antennae of S.anoplophorae are filiform,with one scape,one pedicel,and 33 flagellomeres in females,and one scape,one pedicel,and 31 flagellomeres in males.Eight types of sensilla were present in the antennae of S.anoplophorae,including B?hm bristles,chaetica sensilla,trichoid sensilla,placodea sensilla,coeloconic sensilla,styloconica sensilla,sensilla squamiformia,and smell pore.[Conclusion]The ultrastructural analysis revealed that the distribution of sensilla on the antennae of S.anoplophorae was generally similar between females and males.However,significant differences were observed in the overall length and width of the antennae,as well as in the size,type,and number of sensilla on different segments.These findings provide a solid foundation for future studies on the chemical communication and olfactory behaviors of S.anoplophorae.
