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.

Key words: insect, symbiotic bacteria, insecticide resistance, resistance mechanism
