摘　　要：本文研究了光肩星天牛(Anoplophora glabripennis Motsch)(Coleoptera: Cerambycidae)成虫的生殖力、求偶行为以及是否存在性外激素等问题。结果表明,该天牛成虫的生殖力因补充营养取食的树种而不同。其交配行为是,当两性相距较远时,雌虫可能释放一种性外激素,引诱雄虫定向飞行或步行,当雌性激素单独把雄虫引到激素源时,雄虫猛地转向雌虫,是由视觉刺激引起的,也可认为,视觉刺激和嗅觉刺激彼此连带着起作用。The fecundity and mating behavior of the longcorn beetle Anoplophora glabripennif were studied in the laboratory and in the field. The results showed that the fecundity was in-fluenced by the species of the host trees infested and the tactic orientation of the male beerle at long distance toward the female beetle was mediated by the secretion of sex pheromone of the latter. At close distance, however, the dash of the male beetle toward a female beetle was elicited by visual stimulus from the later. Therefore, sex pheromone and visual stimulus from the female beetle acted together for the male beetle to find its mate.
