两种关系密切的拟寄生蜂Cotesia glomerata（L.）和红绒茧蜂Cotesia rubecula（马歇尔）对植物气味的联想学习是不同的。为了提供一个坚实的基础，为我们的研究机制，这种差异的基础上，我们描述了这两个物种的触角感器的形态，利用扫描电子显微镜辅以透射电子显微镜。两种昆虫的雌、雄触角均具有相同的六种感受器。我们将这些感器分为无孔感器、具顶孔感器、具壁孔感器、腔锥感器I型、腔锥感器II型和板状感器。我们的结论是，在这两个密切相关的黄蜂物种的形态，数量和分布的感觉受体是高度相似的。种间和性别间的差异仅表现在板形感器的数量上。C. rubecula比C.与同一物种的雌性相比，这两个物种的雄性都具有更大的数量和更高的板状感器密度。(C)2004 Wiley-Liss，Inc.
Two closely related parasitoid wasp species, Cotesia glomerata (L.) and Cotesia rubecula (Marshall) (Hymenoptera:Braconidae), are different in their associative learning of plant odors. To provide a solid basis for our research on the mechanisms that underlie this difference, we described the morphology of the antennal sensilla of these two species using scanning electron microscopy complemented with transmission electron microscopy. Female and male antennae of both species have the same six types of sensilla. We classified these sensilla as sensilla trichodea without pores, sensilla trichodea with a tip pore, sensilla trichodea with wall pores, sensilla coeloconica type I, sensilla coeloconica type II, and sensilla placodea. We conclude that the morphology, numbers, and distribution of the sensory receptors are highly similar in these two closely related wasp species. Differences between species and sexes occurred only in sensilla placodea numbers. C. rubecula has more sensilla placodea than C. glomerata and males of both species have a larger number and a higher density of sensilla placodea compared to females of the same species.
