The invention relates to the field of agricultural plant protection, in particular to an environmentally-friendly prevention and control method for tobacco pests. The method is used for replacing environmentally-friendly prevention and control methods which adopt chemical pesticides for the tobacco pests. The provided environmentally-friendly prevention and control method for the tobacco pests includes the steps that according to the pest larva damage condition and economic threshold value of each tobacco area, prevention and control objects are determined; according to adult pest occurrence dynamics, larva occurrence dynamics, larva damage time and the growth period of tobacco plants, the best use period of an environmentally-friendly prevention and control technology of the tobacco areasis determined; a mature biological prevention and control technology, a physical and chemical deception and control technology, a biological preparation prevention and control technology and an ecological control technology are integrated; three major technologies including the technology for preventing and controlling aphids by using aphidiidae, the technology for preventing and controlling tobacco noctuids by using a sexual attractant and the technology for preventing and controlling scarabs by using photoinduction are used as the main line, and by combining with agricultural prevention andcontrol and physical prevention and control (gauze, film and the like), 'three preventions and one resistance' environmentally-friendly prevention and control is carried out on the aphids, the noctuids (prodenia litura, black cutworm, cotton bollworm, oriental tobacco budworm, tobacco stem borer), the scarabs and other mainly harmful tobacco pests.
