摘要:本文利用扫描电子显微镜对咖啡脊虎天牛(Xylotrechus grayii White)雌雄成虫触角感器
的种类、特征、数量和分布进行观察,为咖啡脊虎天牛生理和行为的研究提供了重要基础。
研究结果发现,在雌雄成虫触角上共有 5 类感器,包括刺形感器的 6 种亚型,锥形感器的 5
种亚型, Böhm 氏鬃毛,凹槽钉形感器,钟形感器。其中,刺形感器的数量最多,锥形感
器的数量次之,其余三类感器数量均较少。咖啡脊虎天牛雌雄成虫触角感器在种类和数量上
没有显著的差异,锥形感器在分布上有一定的差异。锥形感器在雄性成虫触角上的集中分布
现象比雌性成虫触角上的明显。

Abstract: In this paper, the types, characteristic, quantity and distribution of the antennae
sensilla of both sexes of adults, Xylotrechus grayii White. (Coleoptera, cerambycidae), were
researched with scanning electron microscopy. This study can provide important foundation for
the research of behaviors and the physiology of Xylotrechus grayii White. Five types of sensilla
were observed on the antennae including six subtypes of sensilla chaetica, five subtypes of sensilla
basiconica, one type of Böhm bristles, one type of grooved peg sensilla and one type of sensilla
campaniformia. The quantity of sensilla chaetica was the largest followed by sensilla basiconica,
and the quantity of others was the least. No significant sexual differences in the types and number
of the antennae sensilla were discovered, and the distribution of sensilla basiconica was different
between both sexes. There were more significant concentrated distribution of sensilla basiconica
on the male antennae than on the female antennae.
