利用透射电镜观察了昆士兰州实蝇Bactrocera tryoni（Froggatt）的触角感受器。结果表明，该虫的感受器有6种类型：多孔双壁型（Mp-dw）、多孔单壁型（Mp-sw）（4个亚型）和无孔感受器（Np-is）。根据壁厚和壁、孔和树突结构的差异对Mp-sw感器进行分类。Mp-dw感受器由2或3个不分枝的树突支配。Mp-sw厚壁感受器有1 ~ 2个感受细胞，感受细胞的树突在轴内有有限的分支。Mp-sw薄壁感受器由2或3个感觉细胞支配，树突在轴内广泛分支。Np-1 s感受器以前从未在实蝇触角上发现过，只在触角的感觉窝中发现。它们的外壁呈颗粒状，由3个感觉细胞支配，其中只有2个将树突投射到毛腔中。对感器的功能进行了讨论。(C)1997 Elsevier Science Ltd.
Antennal sensilla of the Queensland fruit fly, Bactrocera tryoni (Froggatt) (Diptera: Tephritidae) were examined using transmission electron microscopy. Six sensillar types were recognised: a multiporous double-walled type (Mp-dw), multiporous single-walled types (Mp-sw) (4 subtypes) and no-pore sensilla with inflexible sockets (Np-is). The Mp-sw sensilla were categorised on the basis of wall thickness and differences in wall, pore and dendrite structure. The Mp-dw sensilla are innervated by 2 or 3 unbranched dendrites. The Mp-sw thick-walled sensilla have I or 2 sensory cells, whose dendrites,show limited branching within the shaft. The Mp-sw thin-walled sensilla are innervated by 2 or 3 sensory cells with dendrites that branch extensively within the shaft. The Np-is sensilla have not previously been described from tephritid antennae, and are found only in the antennal sensory pit. They have a granular appearance to the exterior walls and are innervated by 3 sensory cells, only 2 of which project dendrites into the hair lumen. The proposed functions of the sensilla are discussed. (C) 1997 Elsevier Science Ltd.
