摘　　要：【目的】研究新疆马铃薯种植区科学识别和防控马铃薯瓢虫(Henosepilachna Vigintioctomaculata)。【方法】采用普查和定点调查,研究马铃薯瓢虫在新疆的发生分布和危害情况,描述其形态特征;提出阻截策略和应急防控措施。【结果】2020年6月在新疆伊犁哈萨克自治州察布查尔锡伯自治县发现马铃薯瓢虫,发生面积6.12×10 hm^(2),主要寄主为马铃薯Solanum tuberosum L.、番茄Solanum lycopersicum以及龙葵Solanum nigrum L.等,其中马铃薯上危害较重,平均发生虫量5头/株,最高达27头/株。【结论】马铃薯瓢虫在新疆首次发现,其局部为害较为严重,应加强其识别与早期阻截防控。【Objective】To provide reference for scientific identification and control of potato ladybug in potato planting area of Xinjiang.【Methods】In this paper,the occurrence,distribution and harm of ladybird potato in Xinjiang were identified for the first time,and its morphological characteristics were described.Combined with literature review,the prevention and treatment strategies and measures were preliminarily proposed.【Results】Henosepilona Vigintioctomaculata,which occurred in an area of 61.2×10 hm^(2),was discovered in Xinjiang for the first time in June 2020 in Qapurchal Xibo Autonomous County,Yili Prefecture.The main hosts were Solanum tuberosum L.,Solanum lycopersicum and Solanum nigrum L.,etc.Among them,the damage to potato was the most harmful,and the average occurrence rate of adult was 5,and the highest was 27.【Conclusion】The potato ladybug is first found in Xinjiang.It has a high risk of spreading and poses a potential threat to the development of the potato planting industry in the area,so it is necessary to strengthen its identification and prevent and control them earlier.
