摘　　要：栗山天牛Massicus raddei(Blessig)是中国栎树类树种的主要蛀干害虫,在吉林省和辽宁省主要危害蒙古栎Quercus mongolica和辽东栎Quercus liaotungensis的主干,给当地造成了重大的经济损失和生态灾害。为了明确是否有信息化学物质参与到雄性成虫的配偶搜寻和识别过程中,采用行为观测笼,分别对栗山天牛雄虫的视觉和嗅觉作用进行了研究。结果显示:致盲后的雄虫能进行正常的配偶搜寻和交尾,而且正常的雄虫对只有视觉刺激而无化学刺激的蜡封雌虫尸体毫无反应,说明视觉对雄虫搜寻配偶所起的作用很小。切除7节以上鞭节的雄虫交尾次数大大下降,切除全部9节鞭节的雄虫完全不能实现交尾行为,而切除全部鞭节的雌虫能正常交尾,说明雄虫的触角特别是其端部7节鞭节在识别配偶并成功交尾方面起着重要的作用,并且可能由其感受雌虫所释放的信息化学物质。Massicus raddei （Blessig） is a main wood borer of chestnut tree in China and it attacks the trunk of Quercus mongolica and Quercus liaotungensis in Liaoning and Jilin provinces, Northeast China. It has already caused serious damage to the local economy and forest ecology. In order to explore whether semiochemicals would help the male matesearching, we devised a bioassay cage to observe the searching and mating behavior of male adults of M. raddei, and to access their visual and olfactory capability from their behavior. The results showed that the blind males could have normal searching and mating behavior. The normal males had no behavioral response to dead females enveloped with paraffin. Both results indicated that vision plays little role on the process of males searching for females. The searching and mating ability of males, with seven segments of antennal flagella removed significantly decreased. Removing whole antennal flagella would deprive the mating capability of males. However, the females who lost the whole antennal flagella could still successfully mate with the normal males. These results suggest that male antennae, especially the terminal seven segments, play important roles in searching and mating behavior of males and may contribute to sensing the semiochemicals released from females.
