The development of forest entomology in China has been more than 100 years, and with the continuous development of new technologies such as molecular biotechnology, computer information technology, and space remote sensing technology, researches on forest insects in China have made remarkable achievements in every branch. Here we summarized the research progress and achievements of forest entomology in China over the past 10 years in terms of taxonomy, phylogeny, biogeography, biology, ecology, and pest control of forest insects. In addition, the developmental trends of forest entomology research in China in the future are also prospected in this article.
