Main environmental factors for forestry insects that become important pests

Abstract: This paper discussed why some insects become pests with primary reasons being clarified in order to control pest of forest in the future. These reasons included drought, atmospheric pollution, consequences of global change, and exotic invasive species. Moreover, three key points for rationally allocating different tree species to forests, so as to prevent pest disasters, were put forward, namely:biodiversity to enhance ecosystem stability, a risk dispersing mechanism, and a relative resistance principle. Based on regulation of tree species distribution and time-space structure in forest ecological systems must either promote pest control or at least not increase forest pest damage.
