中文摘要：

金龟甲类是危害严重的地下害虫,利用化学信息素可以有效监测与防治金龟甲。昆虫触角感器是感受外界信息素的主要器官。利用扫描电子显微镜对暗黑鳃金龟（Holotrichia parallela Motschulsky）、华北大黑鳃金龟（Holotrichia oblita Faldermann）和铜绿丽金龟（Anomala corpulenta Motschulsky）成虫的触角形态及感受器超微结构进行研究。结果表明,暗黑鳃金龟和华北大黑鳃金龟鞭节棒状部由5节组成,铜绿丽金龟由4节组成。暗黑鳃金龟触角感器有10种,华北大黑鳃金龟触角感器有8种,铜绿丽金龟触角感器有9种。3种金龟甲雌、雄个体之间触角感器的类型、分布均无明显差异,但不同感器在触角各节上的数量存在差异。研究结果对科学理解金龟甲类害虫感知信息化合物有一定参考。

英文摘要：

Scarabs are important underground pests.Scarabs have been effectively monitored and controlled using semiochemicals.Antennal sensillas of insect are the major organs sensing pheromone.of the outside.The antennae morphology and sensilla of Holotrichia parallela Motschulsky,Holotrichia oblita Faldermann and Anomala corpulenta Motschulsky were observed by scanning electron microscope.The results showed that the funicle of H.parallela Motschulsky and H.oblita Faldermann have 5segments,whereas the funicle of A.corpulenta Motschulsky consists of 4segments.The antennae of H.parallela Motschulsky contain 10 kinds of sensilla,8types of sensilla on H.oblita Faldermann and 9types of sensilla on A.corpulenta Motschulsky.No difference was found in the type and distribution of the sensilla between the male and female adults.The numbers of each sensillum,however,were different in different segments of the antennae.The results can provide some references forscientific understanding of the scarab beetle＇s sense of semiochemicals.
