The invention relates to an artificial method massively producing insect natural enemies; the method comprises the following steps: under the temperature of 22-27 DEG C and humidity 50-80% conditions, using snake beans to massively breed Frankliniella occidentalis; using Frankliniella occidentalis to artificially and massively produce insect natural enemies, wherein the insect natural enemies comprise Predatory Mite, predatism thrips, predatism bugs, ladybugs, Chrysopa perla, rove beetles, plant parasitic nematode, pathogenic fungi and parasitic wasps. The artificial method massively producing insect natural enemies is complex in operation and high in cost; compared with a conventional method in which other preys are employed to produce the insect natural enemy, the same insect natural enemy produced by the novel method can fast adapt to Frankliniella occidentalis control, thus improving Frankliniella occidentalis control effect.
