The invention relates to a method for artificial mass production of ladybugs and green lacewings. The method is characterized in that spider mites and aphids are bred by host plants and then the ladybugs and the green lacewings are bred by bred preys. According to the method, the host plants and the preys are not placed in ladybug and green lacewing breeding boxes, but a mass of ladybugs and green lacewings are bred in an open environment of a breeding room without insect breeding cages and isolation. The method has the advantages that not only are prey, ladybug and green lacewing breeding methods provided, but also a ladybug and green lacewing collection method, a ladybug and green lacewing packaging method and a cultivating matrix treatment and reutilization method are provided; although the ladybugs and the green lacewings collected and packaged according to the method are mainly larvae, mass breeding of the ladybugs and the green lacewings can be also achieved, and not only can a great quantity of natural enemy resources be provided for biological prevention and control of agricultural pests, but also manpower, resources and cost can be saved.
