%X The effects of Dimilin on the insect community diversity were studied in masson's pine, Pinus massoniana, stands in the central hill of Hunan Province. The results indicated that the species composition and the diversity degree of Lepidoptera, Orthoptera, Hymenoptera insects and spiders were influenced by Dimilin after its application. The influences on the former two order insects were direct,and those on the Hymenoptera insects and spiders were indirect. In the action of Dimilin, the diversity levels of Lepidoptera and Orthoptera insect of the treatment plot had a certain degree decline, and the diversity degrees of Hymenoptera insect and spider had a large increase, thus insect community in the treatment stand tended to be relatively stable. However, because Dimilin had no direct effect on the population of aphis, this stability of insect community was easily disturbed by the rapid increase of aphis population.
