黄斑星天牛(Anoplophora nobilis G.)是我国北方地区杨树毁灭性蛀于害虫。本文总结了作者在1980——1981年于陕西省陇县及甘肃省甘谷县就其成虫行为,以及引起某种行为的机理的研究成果。该种成虫行动迟钝,一昼夜有两个活动高峰,主要是取食和交尾。飞翔力不强,最远距离为1190米。其活动力的强弱受温度的影响,16—28℃为正常活动范围。成虫在树干上产卵,离地面的高度,随树龄增加而逐年上升。研究发现,成虫主要通过触角,准确地选择在大官杨上产卵,因该树种含有某种化学物质引诱所致。从而为综合治理提供新依据。
Anoplophora nobilis G. is a devastating species of poplar in northern China. This paper summarizes the research results of the authors about their adult behavior and the mechanism that caused certain behaviors in Long County of Shaanxi Province and Gan Valley County of Gansu Province from 1980 to 1981. The adult is slow to act and has two peak activities throughout the day and night, mainly feeding and mating. Flying is not strong, the longest distance of 1190 meters. The strength of its activity by the temperature, 16-28 ℃ for the normal range of activities. Adults lay their eggs on tree trunks, rising from the ground with increasing age. The study found that adults mainly through antennae, accurately choose to lay eggs in the big male, because the tree species contains a chemical induced. Thus providing a new basis for comprehensive management.
