Sensory structures (sensilla) of insects are present in high number in the antennae are important for perceiving environmental cues. Thus, sensilla play an important role in the localization, discrimination, and acceptance of a possible host by parasitoid insects. The sensilla, classified according to their shape, size, and distribution, may also show sexual dimorphism in insects. The types and distribution of antennal sensilla in female and male parasitoid Trichospilus pupivorus (Ferriere, 1930) (Hymenoptera: Eulophidae) were evaluated. T. pupivorus females had longer antennae than males. Both males and females have ten sensilla types with higher abundance of placoid sensilla in females, which suggest a possible functional dimorphism.
昆虫的感觉结构(感器)在触角中大量存在,对于感知环境线索非常重要。因此,感器在寄生性昆虫对潜在宿主的定位、识别和接受中起着重要作用。感器根据其形状、大小和分布进行分类,在昆虫中也可能表现出性别二态性。本研究评估了雌性和雄性寄生蜂长尾小蜂 Trichospilus pupivorus(Ferriere,1930)(膜翅目:长尾小蜂科)触角上感器的类型和分布。雌性长尾小蜂的触角比雄性长。雌雄两性都有十种感器类型,雌性中板状感器的丰度更高,这表明可能存在功能二态性。
