摘  要：
为确定不同种类夜蛾口器及其感器在超微结构上的差异,采用扫描电子显微镜对棉铃虫Helicoverpa armigera(Hübner)、烟夜蛾H.assulta(Guenée)和银纹夜蛾Argyrogramma agnata(Staudinger)3种鳞翅目(Lepidoptera)夜蛾科(Noctuidae)重要农业害虫雌、雄成虫口器感器的超微形态进行了观察和比较。结果表明:3种夜蛾雌、雄成虫口器感器类型均无明显差异。棉铃虫和烟夜蛾口器感器在类型和形状上十分类似,均具有毛形、锥形和栓锥形感器;喙管末端的栓锥感器粗、密,棱纹明显。银纹夜蛾口器感器与两种铃夜蛾区别明显,除上述3类感器外,还具有腔锥形感器;其喙管末端的栓锥感器细、疏,棱纹不明显。结果显示口器感器可用于夜蛾的分类及亲缘关系研究。

摘  要：
The ultramorphology of sensilla on the proboscis in three pest noctuid moths of agricultural significance, the cotton bollworm Helicoverpa armigera (Hübner), the Oriental tobacco budworm moth H. assulta (Guenée), and the silver looper moth Argyrogramma agnata (Staudinger), were investigated using scanning electron microscopy and compared to reveal the ultramorphological differences of the proboscis sensilla among these noctuid moths. The results showed that sexual dimorphism is not found in types of the proboscis sensilla in these species. The proboscises in H. armigera and H. assulta are similar in sensillum types and morphology, sharing similar sensilla trichodea, sensilla basiconica, and sensilla styloconica. Sensilla styloconica bear prominent ridges and are densely borne on the distal part of the proboscis. The proboscis in A. agnata, however, bears sensilla coeloconica in addition to the three types of sensilla mentioned above; sensilla styloconica are slender, lack prominent ridges, and are sparsely distributed on the distal part of the proboscis. The results suggest that the proboscis sensilla can be used in the classification and phylogenetic analysis of the Noctuidae.
