Abstract: 【Objective】 To clarify the occurrence and harm of Sphaerolecanium prunastri in wild fruit forests and provide scientific basis for the effective prevention and control of the pest. 【Methods】 Seven wild apricot concentrated distribution areas in wild fruit forests in Xinjiang were selected as site plots from 2019 to 2020 to investigate the number and victimization degree of S. prunastri on Armeniaca vulgaris by visual method. 【Results】 Number of S.prunastri was different in different affected grades of A. vulgaris. The maximum number of first-instar nymphs of S. prunastri was 1108.46 per 50 cm branch, and there was a significant positive correlation with the number of female adults of the previous generation. The occurrence and harm of S. prunastri were different at different survey sites. Among them, the number of S. prunastri was the largest in Saha of Gongliu County, and the damage index of wild apricot was relatively high. The occurrence of S. prunastri was less in Jiaotuohai of Xinyuan County, where the damage index of A. vulgaris was the lowest. Nevertheless, there was an increasing trend from 2019 to 2020. 【Conclusion】 The spread speed of S. prunastri in the wild fruit forests area and the surrounding agricultural area is relatively fast and the control is difficult. It is suggested to seize the best time to control S. prunastri and adopt regional control strategy to control the spread of the pest.
