The Entomological Society of China (ESC) is the largest non-government organization in the world serving the professional and scientific needs of entomologists and people in related disciplines. 1. Founded in 1944, the ESC has more than 13800 members affiliated educational or research institutions, health agencies, private industry, and the Chinese government. Members are researchers, teachers, extension service personnel, administrators, marketing representatives, research technicians, consultants, students, and hobbyists. 2. The ESC is a not-for-profit professional society governed by a board comprised of members. ESC is affiliated with the China Association for Science and Technology and its headquarter is attached to the Institute of Zoology, Chinese Academy of Sciences, Beijing. 3. The ESC holds together members and organizes various academic activities in promoting the development of science and technology in the fields of entomology. The society endeavors to popularize scientific knowledge and plays an advisory role in solving important problems related to insects and in entomological theories. The purpose of the society is to promote entomology for the advancement of science and the benefit of society through: scientific and professional communications, outreach on science and public policy, program development, continuing education, and fostering interest in entomology. 4. ESC is vivid in international affairs and has wide relationship with many foreign societies and institutions. Now ESC has established bilateral and multilateral cooperation with the Convention of Biological Diversity, the International Society of Entomology, the Asia-Pacific Entomological Association, and etc. 5.

Activities of the ESC can be roughly grouped into following categories: meeting, programming, consulting and popularizing on entomology. The premier event of the Society is its Annual Meeting. 7. The society have 6 working committees (Science Popularization, Technical Consulting, International affairs, Organizing, Youth, Financial), and 12 special academic committees (Insect Faunistics and Systematics, Insect Physiology and Biochemistry, Ecology, Insecticide and Toxicology, Agricultural Entomology, Forest Entomology, Medical Entomology, Biological Control, Insect Resources, Urban Entomology, Acarology, and Butterflies). 8. The ESC offers journals that provide unsurpassed coverage of the broad science of entomology. The society publishes scientific journals, such as Acta Entomologica Sinica, Insects Science, Chinese Journal of Applied Entomology (former Entomological Knowledge), Acta Zootaxonomica Sinica, and Acta Parasitologica et Medica. 9. The ESC is seeking for new routines to meet the needs of developments of sciences, communities, and economy.
