摘要：黄脊竹蝗是中国南方地区重要的竹子害虫,为了更好地理解黄脊竹蝗"趋尿行为"的生理生化机制,通过电镜扫描技术研究了黄脊竹蝗成虫触角感器的类型、数量、形态及分布特征,比较分析了其在雌、雄成虫间的差异。结果表明:黄脊竹蝗雌、雄成虫触角丝状,由1节柄节、1节梗节和23节鞭节构成,雌雄间触角长度及直径差异不显著(P>0.05);雌、雄成虫触角感器均有毛形感器Ⅰ、毛形感器Ⅱ、刺形感器、锥形感器Ⅰ、锥形感器Ⅱ和腔锥形感器6种;其中,锥形感器数量最多,约占感器总数的53%,主要分布在鞭节的第8～21亚节上;各类感器在雌、雄成虫间触角上的分布特征相似,雄成虫触角上感器总数、锥形和腔锥形感器数量显著多于雌成虫(P<0.05)。
Yellow-spined bamboo locust Ceracris kiangsu is an important bamboo pest in South China. To better understand the physiological and biochemical mechanisms of the pest ‘urine puddling’ behavior, scanning electron microscopy was employed to examine the type, number, external morphology, and distribution of C. kiangsu adults antennal sensilla, and the differences in these aspects between male and female adults were compared. The antennae of male and female C. kiangsu were filiform in shape, and consisted of 1 scape, 1 pedicel, and 23 flagellomeres. The length and width of the antennae were similar between the males and females （P0.05）. Six types of sensilla were recorded for the males and females, including sensilla trichodea Ⅰ, sensilla trichodea Ⅱ, sensilla chaetica, sensilla basiconica Ⅰ, sensilla basiconica Ⅱ, and sensilla coeloconica. The sensilla basiconica had the largest number, occupying about 53% of the total, and concentrated on the 8th-21st flagellar segments. Both the males and the females had the similar distribution characteristics of each sensilla on the antennae. The total number of the males sensilla was significantly higher than that of the females sensilla （P0.05）, and the males had a significant larger number of sensilla basiconica and sensilla coeloconica, as compared with the females （P0.05）.
