Recently, Cash Crop and Pest Monitoring and Control Innovation Team, Institute of Plant Protection, Chinese Academy of Agricultural Sciences, has systematically analyzed the global invasion pattern of the western flower thrips, on of the world's major agricultural pests. They also proposed an effective comprehensive prevention and control strategy to provide an important scientific basis for a deeper understanding of this major invasive species.
The western flower thrip is native to North America and is distributed throughout the Americas, Europe, Asia, Africa, Oceania, in more than 50 countries. It has become a major agricultural pest in the world. At present, in 2003, since the discovery of the western flower thrip in the greenhouse near Beijing, it has been reported in many provinces (and autonomous regions) such as Yunnan, Hebei, Zhejiang, Shandong, Jilin, Jiangsu, Guizhou, Xinjiang, etc. This pest will eat the stems, leaves, flowers, and fruits of the plants, causing the plants to wither and is also the main vector for major viruses such as TSWV (the tomato spotted wilt virus). Its host range is wide, and its host plants including the potato, eggplant, pepper, cucumber, flowers, banana, mango and other more than 500 important cash crops and food crops. The research shows that with the rapid development of international trade and the general increase of chemical pesticide resistance, the western flower thrips have invaded and spread on a global scale, and have intensified the spread of tomato spotted wilt virus on various crops. It has become a major pest in agriculture and has formed a new global invasion pattern.
The article further pointed out that within the current trend, reducing the use of chemical pesticides, delaying the development of drug resistance, and strengthening the comprehensive prevention and control strategy based on green prevention and control technology on a global scale is urgent and imperative.
Oregon State University, Keele University, University of California, University of California, Wageningen University and Research Center, and local universities in the United States contributed to the research. The study was funded by a national key research and development program.
