Arbuscular mycorrhizal (AM) fungi which distribute widely in soils can colonize plant roots and form the most popular mutual symbionts with host plants. AM fungi occupy irreplaceable niche, play key roles in evolution, community succession, regulation of physiology and chemistry, growth and development of host plants. The fungi can also increase of biodiversities, soil quality, ecosystem stabilization and sustainable productivity through direct and/or indirect ways. While insects are also important components in ecosystems, depending on and impacting greatly plants. Thus, AM fungi and insects are important components of most ecosystems, which are likely to interact with one another directly and indirectly in AM fungi-plants-insects system. Although the investigation on influence of AM fungi on insects started to be estimated in 1980s', more widely investigations on the interactions between AM fungi and insects were carried out only in 21^st century, and especially the interactions between AM fungi and insects have been well recognized in recent years. In this review, we summarize the influence of AM fungi on insect feeding preference, growth, reproduction and damage to plants, and the impacts of insects on colonization, growth and development of AM fungi, with more recent experiment results being introduced; discuss the possible mechanisms of the interaction between AM fungi and insects, and the impact characters of plant nutrition, insect gender, insect instars, and AM fungus species' influencing the interactions; and evaluate roles of inhibiting pests, and enhance natural enemy of pests and pollinator insects by AM fungi. The information of this paper should add the contents in mycorrhizology, promote the study of mycorrhizal fungi and insect interactions, and to provide the basis for explore new pathways in biological control of agricultural, forest, and forage feed pests.
