【目的】 明确为害黄芪种子的黄芪籽蜂Bruchophagus sp.雌成虫触角及产卵器上的感器类型及分布特点，以期为探讨这些感器在黄芪籽蜂雌虫的嗅觉和产卵过程中的作用奠定基础。【方法】 采用扫描电镜对黄芪种子小蜂Bruchophagus huonchili Liao et Fan、内蒙黄芪籽蜂Bruchophagus mongholicus Fan et Liao和北京黄芪籽蜂Bruchophagus beijingensis Fan et Liao 3种黄芪籽蜂雌成虫触角和产卵器上的感受器进行观察，并对各感器的形态特征、类型、数量及分布进行比较分析。【结果】 3种黄芪籽蜂雌成虫触角上的感器类型基本一致，包括毛形感器、刺形感器、板形感器、薄壁化学感器、厚壁化学感器和锥形乳头状感器6类，感器数量上3种黄芪籽蜂存在显著差异（P<0.05）。薄壁化学感器是触角上分布最广、数量最多的一类感器，且在3种黄芪籽蜂中存在显著差异（P<0.05）。3种黄芪籽蜂雌成虫产卵器的形态和感器类型相差较大，其中黄芪种子小蜂有毛形感器（毛形感器Ⅰ和毛形感器Ⅱ）和倒钩状突起2类感器；北京黄芪籽蜂产卵器有毛形、锥形、刺形和倒钩状突起4类感器；内蒙黄芪籽蜂产卵器有浅凹状感器、芽孢形等8类感器。其中毛形感器和倒钩状突起是3种黄芪籽蜂雌成虫产卵器上共有的感器类型。【结论】 3种黄芪籽蜂雌成虫触角感器类型基本一致，但产卵器感器类型差异较大。内蒙黄芪籽蜂雌成虫触角感器数量最多，产卵器感器种类最丰富，推测其在嗅觉感受和产卵选择行为中的优势更大。

[Objectives]  To clarify the types and distribution of sensilla on the antennae and ovipositor of adult females in three Bruchophagus species, in order to provide a foundation for investigating the role of these organs in olfaction and oviposition. [Methods]  Sensilla on the antennae and ovipositor of adult female Bruchophagus huonchili Liao et Fan、Bruchophagus mongholicus Fan et Liao and Bruchophagus beijingensis Fan et Liao, were observed under scanning electron microscopy and their morphological characteristics, type, quantity and distribution were analyzed and compared. [Results]  Sensilla were basically similar in all 3 species. There are six kinds of antennal sensilla; trichodea sensilla, chaeticum sensilla, placoid sensilla (placoid sensilla Ⅰ, placoid sensilla Ⅱ, placoid sensilla Ⅲ), thin-walled chemoreceptor, thick-walled chemoreceptor and basiconic mastoid sensilla. However, there were significant differences in the number of sensilla among species. The thin-walled chemoreceptor is the most widely distributed and most abundant sensilla on antennae, and there are significant differences in the abundance of this type of sensilla among the three species. The ovipositor morphology of the three species and corresponding sensilla types are quite different. B. huonchili has sensilla trichodea (sensilla trichodea Ⅰ and sensilla trichodea Ⅱ) and barb-like apophyses, B. beijingensis has 4 types of sensilla (sensilla trichodea, sensilla basiconca, sensilla chaetica and barb-like apophyses) and B. mongholicus has 8 types of sensilla, including those with a slight surface depression and bud-shaped sensilla. Trichodea sensilla and barb-like apophyses are common to all three species. [Conclusion]  The sensilla on the antennae of female adults of three Bruchophagus species are basically the same, but those on the ovipositor are quite different. Adult female B. mongholicus have the largest number of antennal sensilla and the most diverse ovipositor sensilla. This suggests that this species has superior olfactory perception and oviposition site selection.
