摘要
沙漠蝗Schistocerca gregaria是世界性重大害虫,分布于非洲、亚洲和欧洲的65个国家和地区。食物和温度是造成沙漠蝗暴发的重要因素。本文综述了沙漠蝗重点为害区域的植被特征,证实沙漠蝗可取食8科11属300余种植物;对温度与沙漠蝗种群动态的关系进行分析,发现沙漠蝗可在18.5℃以上、46℃以下生活,温度适应性强;并对沙漠蝗在非洲、亚洲及欧洲的国家或地区的适生性进行对比,结合温度和食物因子分析,探讨了沙漠蝗在我国的潜在分布区域,并从防治理念和技术手段等方面对沙漠蝗的防治进行了展望。为防止沙漠蝗入侵为害我国,建议应加强西藏自治区和云南省等边境地区沙漠蝗的监测预警工作。
Desert locust Schistocerca gregaria is one of the major pests in the world,distributed in 65 countries and regions including Africa,Asia and Europe.Temperature and food are important factors causing S.gregaria outbreaks.In this study,the vegetation characteristics of S.gregaria in key areas were summarized.It was found that S.gregaria could feed on more than 300 species of plants in 11 genera and eight families.The relationship between temperature and the population dynamics of S.gregaria was clarified.S.gregaria had a strong temperature adaptability and could live above 18.5℃and below 46℃.Comparative analysis of the suitability of desert locusts in different countries or regions in Africa,Asia,and Europe,combined with the analysis of temperature and food factors,clarified the potential distribution areas of S.gregaria in China.In addition,the prevention and control of desert locusts were predicted in terms of control concepts and control means.Therefore,in order to prevent S.gregaria from invading China,the monitoring and early warning work in Tibet Autonomous Region,Yunnan Province and other border areas in China should be strengthened.
