摘　　要：【目的】咖啡灭字脊虎天牛是咖啡树上的主要害虫,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,需研究掌握普洱咖啡灭字脊虎天牛发生的影响因素。【方法】选取了切干和不切干的咖啡树、不同树龄、树势、不同坡向、不同位置的咖啡园进行了调查,应用差异性和灰色系统分析了影响普洱咖啡灭字脊虎天牛发生的环境因素和气候因子。【结果】咖啡灭字脊虎天牛的发生与咖啡树是否切干、与咖啡树龄、树势、坡向、咖啡园位置有关,从第2年开始,未切干的咖啡树的受害率高于切干的咖啡树;1年生和2年生的咖啡园,咖啡灭字脊虎天牛的受害率差异不显著,而3至8年生及以上的咖啡园,咖啡灭字脊虎天牛的受害率差异显著。不同树势、不同坡向、不同位置的咖啡园中,咖啡树的受害率差异显著。灰色关联度分析表明,对咖啡灭字脊虎天牛幼虫种群数量影响最大的气象因子是降雨量和最低相对湿度,对咖啡灭字脊虎天牛成虫的种群数量影响最大的气象因子是最高温度和平均温度。【结论】咖啡灭字脊虎天牛的发生与咖啡树的切干与否,与咖啡树的树龄、树势、坡向、咖啡园位区及气象因素有关。【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】A systematic investigation was conducted in the stumping and unstumping coffee tree with different age, different growth vigor, different slope direction and different location. The influences of environmental factors and meteorological factor on occurrence of Xylotrechus quadripes Chevrolat were analyzed by difference analysis and the grey correlative degree.【Result】The results showed that the occurrence of Xylotrechus quadripes Chevrolat was relative to stumping or unstumping of coffee tree, different growth vigor, different slope direction and different location of coffee garden. From the second year, the rate of damaged coffee trees in the stumping coffee garden was higher than that of unstumping coffee garden. The rate of damaged coffee trees with 1 and 2 years was no significant difference, but which with 3-8 years and more than 8 years was significant difference. Different growth vigor, different slope direction and different location of coffee garden, the rate of damaged coffee trees was also significant difference. By the grey correlative degree analysis, we found that the meteorological factor effecting on population quantities of larvae of Xylotrechus quadripes Chevrolat were rainfall and the lowest relative humidity, and the meteorological factor effecting on population quantities of adult of Xylotrechus quadripes Chevrolat were the highest temperature and the average temperature.【Conclusion】The occurrence of Xylotrechus quadripes Chevrolat was correlated with the cutting, the age, the growth vigor of the coffee tree, the slope, the location of the orchard.
