Chlorophorus caragana is a species of long-horned beetle that damages Caragana davazamcii Sancz. (Fabales: Papilionaceae) bushes in desert areas in China. The beetles cause substantial damage to local forestry plantations and the environment. Sensilla on the maxillary and labial palps of coleopterans a allow the insects to recognize their host plants. We used scanning and transmission electron microscopy to study the ultrastructure, distribution, and abundance of various sensilla on the maxillary and labial palps of C. caragana. We found four types of sensilla including ten subtypes: one of Böhm's bristles, three of sensilla chaetica, one of digitiform sensilla, and five of sensilla twig basiconica. The types and distribution of the sensilla on the maxillary and labial palps were highly similar between males and females. Finally, this article discusses the functions of the sensilla of related species in recognizing hosts and the significance of gustation studies in the context of the control of C. caragana.
柠条绿虎天牛是一种危害中国沙漠地区中间锦鸡儿（豆目：蝶形花科）灌丛的天牛科昆虫。这种天牛对当地的人工林和环境造成了严重破坏。鞘翅目昆虫上颚和唇须上的感器能让它们识别寄主植物。我们利用扫描电子显微镜和透射电子显微镜研究了柠条绿虎天牛上颚和唇须上各种感器的超微结构、分布及数量。我们发现了四种类型的感器，包括十个亚型：一种博氏鬃毛、三种毛形感器、一种指形感器和五种枝形感器。上颚和唇须上感器的类型和分布在雌雄之间高度相似。最后，本文讨论了相关物种感器在识别寄主中的作用以及味觉研究在柠条绿虎天牛防治中的意义。
