摘　　要：【目的】咖啡灭字脊虎天牛是咖啡树上的主要害虫,该虫以幼虫钻蛀咖啡树干进行危害,对咖啡产业造成了严重的经济损失。【方法】采用野外调查并结合室内饲养观察的方法,对咖啡灭字脊虎天牛的卵和幼虫在咖啡树干上的分布规律及其幼虫和成虫的种群动态、成虫的雌雄性比进行调查分析。【结果】咖啡灭字脊虎天牛的卵主要分布在离地10~60 cm的咖啡树干,幼虫主要分布在离地20~70 cm的咖啡树干。咖啡灭字脊虎天牛的幼虫和成虫1年均有2个明显的峰值,幼虫的第1个峰值出现在7月,第2个峰值出现在10月。成虫的第1个峰值出现在5月,第2个峰值出现在10月。2015-2018年,咖啡灭字脊虎天牛成虫种群个体雌雄性比分别为1.0∶1.1、1.0∶1.2、1.0∶1.2、1.0∶1.3,种群数量以雄性为优势。【结论】研究结果对咖啡灭字脊虎天牛的生态治理具有一定的指导意义。【Objective】Xylotrechus quadripes Chevrolat was the dominant pest of coffee trees.It harmed the coffee trunks with larvae,which had caused serious economic loss.【Method】Distribution of eggs and larvae on coffee trunks,population dynamics larvae and adults,and the ratio of male to female of Xylotrechus quadripes Chevrolat were analyzed by the method of field investigation combined with indoor rearing observation.【Result】The results showed that the eggs of Xylotrechus quadripes Chevrolat were mainly distributed on coffee tree trunks 10-60 cm above the ground,and for larvae on coffee tree trunks 20-70 cm above the ground.In 2015-2018,there were two peaks of population quantity in a year for larvae and adults.The first peak of larvae occurred in July,and the second peak in October.The first peak of occurred in May,and the second peak in October.In 2015-2018,the ratios of male to female of adults were 1.0∶1.1,1.0∶1.2,1.0∶1.2 and 1.0∶1.3,and the male population was dominant.【Conclusion】The results have a certain guiding significance for the ecological management of Xylotrechus quadripes Chevrola.
