中文摘要：

利用扫描电镜对杂拟谷盗成虫触角形态及感器进行了观察,结果表明,杂拟谷盗成虫触角为棒形,由柄节、梗节和鞭节组成,其中鞭节又分为9个亚节,不存在雌雄二型现象。雌、雄成虫触角上均存在以下6类14种感器,包括Bhm氏鬃毛、3种毛形感器、1种栓锥形感器、6种锥形感器、1种刺形感器、2种指形感器。雌雄个体之间触角感器的类型、分布、长度、基部直径没有明显差异。结合感器的形态、分布和已报道的触角电位反应数据,对杂拟谷盗触角各类感器的功能进行了推测。

英文摘要：

Antennal morphology and the sensilla of Triboliurn confusum Jacquelin du Val were studied by scanning electron microscopy. The results showed that the antennae are made up of scape, pedicel and flagellum that con- sisted of 9 segments and there are no dimorphisms on the antennae of the male and female adults. Furthermore, there are 6 kinds and 14 types of sensilla on the antennae of both adults, including 136hm bristles, 3 types of sensil- la trichodea, 1 type of sensilla styloconica, 6 types of sensilla basiconica, 1 type of sensilla chaetica, and 2 types of finger-like sensilla. No difference was found among the types, the distribution, the number, length and diameter of sensilla between both adults. The functions of sensilla were speculated according to their morphology, distribu- tion, and the previously reported electroantennographic responses of Tribolium confusum.
