针对烟粉虱Bemisia tabaci(Gennadius)、温室白粉虱Trialeurodes vaporariorum(Westwood)、黑刺粉虱Aleurocanthus spiniferus(Quaintance)、桑粉虱Pealius mori(Takahashi)、禾粉虱Aleurocybotus indicus David etSubramaniam等粉虱害虫在我国暴发危害的现状,公益性行业科研专项“粉虱类害虫可持续治理技术研究与集成示范”项目组在华南、华东、华北、华中和西南等地区开展了粉虱类害虫的调查、监测、预警以及综合防控技术研究集成与示范。结果表明,烟粉虱在我国的发生区域超过20个省份,温室白粉虱在华北和西南地区,黑刺粉虱在华南、华东和西南地区也分布较广,桑粉虱在我国南方桑植区危害严重,禾粉虱在福建省闽东稻区发生为害逐年严重。利用mt COI DNA测序、SCAR技术和CAPS等技术对B和Q型烟粉虱的鉴定结果显示,Q型烟粉虱在我国的分布范围正在不断扩大。通过Maxent预测模型和GIS技术,预测了烟粉虱在我国的适生区、自然越冬北线和不同地区的发生世代数量。对烟粉虱的抗药性监测结果表明,阿维菌素和烯啶虫胺是目前华北地区防治烟粉虱较为理想的药剂,而对联苯菊酯、噻虫嗪、啶虫脒和吡虫啉等药剂均产生了不同程度的抗药性。研究了苘麻诱集、黄板诱杀、天敌昆虫和病原微生物对粉虱类害虫的控制作用,并在华南、华东、华北、华中和西南等地区建立了12个示范基地,分别在不同地区开展了粉虱类害虫的综合防治技术的示范和推广,累计印刷技术宣传手册12.4万份,培训各类农民和基层农技人员5.43万人次,累计示范面积4.3千公顷次,技术辐射超过4万公顷次,取得了显著的经济、社会和生态效益。
For the whitefly Bemisia tabaci (Gennadius), Trialeurodes vaporariorum (Westwood), Aleurocanthus spiniferus (Quaintance), Pealius mori (Takahashi), Aleurocybotus indicus David et Subramaniam and other whitefly pests The status quo of outbreaks in our country, the scientific research special for nonprofit industries, the research and integration demonstration on sustainable management of whitefly pests project team investigated the whitefly pests in South China, East China, North China, Central China and Southwest China, Monitoring, early warning and integrated prevention and control technology research integration and demonstration. The results showed that B. tabaci occurred in more than 20 provinces in our country. Greenhouse whiteflies were found in North and Southwest China. Blackfly whitefly was also widely distributed in South China, East China and Southwest China. Harmful serious, whitefly in Fujian Province, Fujian Province, rice crop damage has been serious year by year. The identification results of B. tabaci Q and B. tabaci mtDNA using mt COI DNA sequencing, SCAR and CAPS showed that the distribution range of Q-biotype Bemisia tabaci was expanding in our country. By means of Maxent prediction model and GIS technology, the number of generations of Bemisia tabaci in China’s adaptive zone, natural wintering northern line and different regions was predicted. The monitoring results of resistance to B. tabaci showed that avermectin and nitenpyram were the ideal agents to control Bemisia tabaci in North China at present. However, for bifenthrin, thiamethoxam, acetamiprid and imidacloprid Have produced varying degrees of resistance. In this study, we studied the control effects of sesame-boiled, trapped yellow, trapped natural enemies and pathogenic microorganisms on whitefly pests and established 12 demonstration bases in South China, East China, North China, Central China and Southwest China, respectively, in different regions The comprehensive prevention and control technology of whitefly pests demonstrated and promoted a total of 124,000 copies of printed technical brochures and trained 54,300 farmers and grassroots agricultural technicians with a cumulative demonstration area of 4.3,000 hectares and over 40,000 hectares of technical radiation Times, has made significant economic, social and ecological benefits.
