摘要: 我国是世界上最早使用农药防治农作物有害生物的国家之一,也是农药生产和使用的大国。随着化学农药在农林业生产中的广泛应用,昆虫对农药的抗性不断增加,并且已成为农业持续发展和环境保护中的重要制约因素。昆虫抗药性是指昆虫具有耐受杀死正常种群中大多数个体药量的能力,并在其种群中发展起来的现象。目前,已有600多种害虫对不同种类农药产生抗药性且抗药性增长速度呈上升趋势,研究发现昆虫共生菌与昆虫抗药性有关。这些昆虫中以双翅目和鳞翅目昆虫产生抗药性虫种数量最多。综述了昆虫抗药性机制、与昆虫抗药性相关的共生菌类群和相关研究进展,这为昆虫抗药性治理以及农药降解提供了新方向,同时也为当前植保工作奠定理论基础和提供新策略。随着分子生物学技术的快速发展,昆虫共生菌的功能研究将会有明显突破。昆虫共生菌介导的抗药性治理对于环境保护具有重要意义,也为生物防治提供新思路,同时为研究昆虫-微生物的互作奠定研究基础。

Abstract: China is one of the first countries to use pesticide for the prevention and control of crop pests,also is a big country producing and using pesticides. With widely applying pesticides in agriculture and forestry production,the resistance of insects to pesticides is increasing,which has become an important limiting factor in the sustainable development of agriculture and environmental protection. Insect resistance refers to the ability of insects to tolerate doses that kill most individuals in a normal population and this develops in their populations. At present,over 600 pests have developed resistances to different kinds of pesticides,and the growth rate of their resistances is on the rise. Studies have found that insect symbiotic bacteria are related to insect resistance. Among these insects,there is the largest number of resistant insect species in Diptera and Lepidoptera. This paper reviews insect resistance mechanisms,symbiosis groups related to insect resistance and related research progress. With the rapid development of molecular biology technology,the functional research of insect symbiotic bacteria will have an obvious breakthrough. Resistance management mediated by insect symbiotic bacteria is of significance in environmental protection and also provides new ideas for biological control,and lays a research foundation for studying insect-microbial interaction.
