摘要
铃木氏果蝇Drosophila suzukii(Matsumura)是近年来在世界各地备受关注的一种重要入侵害虫,主要为害各种软皮水果和浆果。本研究采用扫描电镜技术观察了铃木氏果蝇雌、雄成虫的触角及下颚须上感器的超微形态。结果发现,铃木氏果蝇触角鞭节上分布着3种表面多孔的感器,分别为锥形、腔锥形和毛形感器。下颚须上分布着锥形和刺形感器。触角和下颚须上的感器形态和数量均无性二型现象。根据锥形感器的大小及表面孔口的形状和大小,又将锥形感器分为小感锥和大感锥。小感锥表面有序排列着凹陷的小孔。大感锥表面成行排列着"一"字形大孔。大感锥仅分布于触角鞭节上,推测是铃木氏果蝇独有的一类感器,或许是长期进化过程中为感受健康新鲜果实的气味而形成的特殊感器。
Drosophila suzukii is becoming a world-wide serious pest. It is a highly polyphagous pest, mainly cau- sing damages to soft fruits. The sensilla on the antennae and maxillary palpi were observed by scanning electron microscope technology. The results showed that there were three types of sensilla on flagellum of the antennae, including sensilla basiconica, sensilla coeloconica and sensilla trichodea. Only sensilla basiconica and sensilla chaet- ica were observed on the maxillary palpi. Sexual dimorphism in structure, distribution and numbers of the other sensilla was not observed. Large and small subtypes of sensilla basieonica were further distinguished. A number of large horizontal bar-shaped pores were distributed on the surface of large sensilla basiconica, while numerous small pores on the surface of small sensilla basiconica. Large sensilla basiconica, a unique type of sensillum not yet ob- served in other Drosophila species, was only distributed on the flagellum of D. suzukii. It might be evolved as a specific type of sensillum for D. suzukii to smell volatiles emitted by healthy and fresh fruits.
