摘　　要：通过对在重庆市潼南区柏梓镇潼南柠檬脱毒种苗繁育中心的4号大棚中设置的6个处理,在化学防治的基础上选择用药后的不同时间释放捕食螨,以探究生-化协同防治柑橘全爪螨的效果.试验结果表明,施用阿维菌素后第6 d释放捕食螨对柑橘全爪螨的防效最好,虫口减退率和防治效果均可以达到98%以上;且相较于单一施用化学农药持效期更长,约为1.5月,而单一施用化学农药持效期只能维持在10 d左右.由气象因子数据和柑橘全爪螨发生动态相关性分析结果可知,施用化学农药后可提高柑橘全爪螨种群对高温的抗逆性;施用阿维菌素后第6 d释放捕食螨天气积分指数对柑橘全爪螨的影响最大,说明微气候也会对柑橘全爪螨的防治产生影响.研究结果为柠檬产业害螨绿色防治提供了更精细化的方案.Through 6 treatments of releasing predatory mites at different times after application of chemicals were set up in No.4 greenhouse of Tongnan Lemon Virus-free Seedling Breeding Center,Baizi Town,Tongnan District,Chongqing,to explore the effect of biological and chemical combination on controlling Panonychus citri.The results showed that the release of predator mites 6 days after the application of avermectin had the best control effect on P.citri.The pest reduction rate and control effect could reach to more than 98%.Compared with the treatment of single application of chemical pesticides,the effective period of treatment was longer at about 1.5 months,while the effective period of single application of chemical pesticides treatment can only be last to about 10 days.According to the correlation analysis results of meteorological factors and the occurrence of P.citri in each treatment,the resistance of P.citri population to high temperature could be improved after application of chemical pesticides.Release of predator mites on the 6_(th) day after application of avermectin,the weather integral index had the greatest effect on the population of P.citri,indicating that appropriate control measures could enhance the inhibition effect of microclimate on the population of P.citri.Regarding the research results provides a more refined scheme for green control of mite in lemon industry.
