Coccinella septempunctata has a strong control effect on aphids and other important pests in agriculture and forestry. The biological control technology of C. septempunctata has already been used in the field. In this paper, the biological characteristics, predation, response to pesticides and artificial rearing of C. septempunctata were reviewed. The larvae of C. septempunctata gradually appeared macular with the growth of instar, temperature and humidity had great influence on its growth and development. It overwinters as adults and exhibits adiapause. C. septempunctata is highly predatory and eats many prey, including aphids, psylla, scale insects, white flies, thrips, net bugs, etc. Its predatory functional response model is mainly Holling II, and its predation effect is affected by temperature, photoperiod, prey density and its own density. C. septempunctata has certain selectivity to pesticides. Its predatory behavior, growth and development are affected by pesticides, causing the development of pesticide resistance. At present, C. septempunctata is mainly raised with insect materials, supplemented by artificial feed, stored at low temperature, and sold with egg cards. The basic research on the application of C. septempunctata would provide a reference for large-scale application in the field in the future.
