【摘要】 [目的]研究绵山天幕毛虫求偶和交配行为,为发展利用性信息素防控绵山天幕毛虫提供理论依据。[方法]通过室内和野外观察,研究绵山天幕毛虫成虫求偶行为的发生过程、求偶周期、不同雌雄比及种群密度对交配率的影响。[结果]自然界中绵山天幕毛虫雌雄比为1.0∶1.2,实验室饲养的绵山天幕毛虫雌雄比则为1.0∶1.8;绵山天幕毛虫的求偶高峰发生在19:00~21:00;不同比例及种群密度对雌雄蛾交配行为影响较大,且种群密度过高不利于其繁殖;绵山天幕毛虫雌、雄蛾一生均只交配1次。[结论]利用性信息素防治绵山天幕毛虫具有较好的应用前景。更多还原

【Abstract】 [Objective] The research aimed to study the courtship and mating behavior of Malacosoma rectifascia Lajonquère and provide theoretical basis for utilization of sex pheromone to prevent and control M.rectifascia.[Method] Through indoor and outdoor observation,effects of M.rectifascia mating behavior occurrence process,courtship period,different sex ratio and population density on mating rate were studied.[Result] The sex ratio of M.rectifascia in nature was 1.0∶1.2,while in lab was 1.0∶1.8;the courtship peak took place from 19:00-21:00;different sex ratio and population density had significant effects on mating behavior,and mating rate would be reduced if the population density was higher;both male and female M.rectifascia mate only once throughout their life.[Conclusion] Controlling M.rectifascia with sex pheromone has good application prospects.更多还原
