利用透射电镜技术对有翅型桃蚜触角感器进行了定位，并对触角感器的囊形感器、腔锥形感器和板形感器的超微结构进行了描述。毛状感器位于触角顶端，由2-4个神经元支配，外树突延伸至毛的末端。初级紫藤的腔锥感器有两种形态类型，均具两个树突。II型腔锥感器的树突被包裹在树突鞘中，含有感器淋巴液。相反，在I型腔锥感器中，树突被电子不透明的固体角质层包围，没有为感器淋巴留下空间。大板状感器的超微结构显示有3组神经元，每组有2-3个树突，而小板状感器只有一组神经元，由3个树突组成。大、小盾形感器外表皮上均有多个气孔。本文还讨论了这些感器的功能。J.

The antennal sensilla of alate Myzus persicae were mapped using transmission electron microscopy and the ultrastructure of sensilla trichoidea, coeloconica, and placoidea are described. Trichoid sensilla, located on the tip of the antennae, are innervated by 2–4 neurons, with some outer dendrites reaching the distal end of the hair. Coeloconic sensilla in primary rhinaria are of two morphological types, both equipped with two dendrites. Dendrites of Type II coeloconic sensilla are enveloped in the dendrite sheath, containing the sensillum lymph. In sensilla coeloconica of Type I, instead, dendrites are enclosed by an electron opaque solid cuticle, with no space left for the sensillum lymph. The ultrastructure of big placoid sensillum reveals the presence of three groups of neurons, with 2–3 dendrites in each neuron group, while both small placoid sensilla are equipped with a single group of neurons, consisting of three dendrites. Both large and small placoid sensilla bear multiple pores on the outer cuticle. The function of these sensilla is also discussed. J. Morphol. 276:219–227, 2015. © 2014 Wiley Periodicals, Inc.
