Abstract: Insect diversity is an important component of biodiversity, while plant and plant community have crucial effects on it. This paper reviewed the effects of plant and plant community on insect diversity from the aspects of 1) the increase of plant height and cover provides insects more living space, and consequently, increases insect diversity, 2) the plant populations with high genetic diversity offer a greater variety of niches, leading to a greater diversity and altered abundance of insect, 3) the increase of plant species and functional group diversity supports the consumers to have more quantities of primary producers, and 4) the increase of plant productivity increases the insect diversity by supplying more food resources. Relevant hypotheses and theories that explained the mechanisms of the effects of plant and plant community on insect diversity were introduced, and the existing research problems and future developments about the effects of plant and plant community on insect diversity were pointed out.
