本文研究了果树害虫脊胸天牛（ＲｈｙｔｉｄｏｄｅｒａｂｏｗｒｉｎｇｉｉＷｈｉｔｅ）在云南景谷县果国内对果树枝干的分布和危害情况。结果表明，该害虫在三年和象牙树上主要危害３～５年生枝条，其有虫枝率分别为６５．３％和９２．０％。另外，按地形将果园分为上、中、下三个区带，分别调查各区活枝、地面枯枝和腐枝中的害虫。结果显示，中区活枝、枯枝、腐枝的有虫枝率分别为６０．０％，３０．０％和１７．０％，其有虫枝率分别高于果园的上区和下区。总体上看，三个区带活枝、枯枝和腐枝的有虫枝率分别为５６．８％，３４．０％和１４．３％。定期清除果国内的枯枝和腐枝是防治脊胸天牛的有效措施之一。
In this paper, the distribution and damage of fruit tree pests RhytidoderabowringiiWhite on the branches of fruit trees in Jinggu County of Yunnan Province were studied. The results showed that the pests mainly endangered 3-year-old branches in three years and ivory trees with 65.3% and 92.0% of them respectively. In addition, according to the terrain, the orchard is divided into upper, middle and lower zones to investigate the live pests in the districts, the litter on the ground and the rots. The results showed that there were 60.0%, 30.0% and 17.0% of live branches, dead branches and rotting branches in the middle area, respectively, and their branch rates were higher than those in the upper and lower parts of the orchard . In general, the rates of live insects in the three zones with live branches, dead branches and rotting branches were 56.8%, 34.0% and 14.3% respectively. It is one of the effective measures to prevent and cure Vertebrae on regular basis to remove the dead branches and rotten branches in the country regularly.
