PROBLEM TO BE SOLVED: To provide a method for insect pest control by natural predator insects for growing in greenhouse. SOLUTION: The method for insect pest control by natural predator insects for growing in greenhouse comprises (1) a first process for artificially growing insects which will not injure object crops and are eaten by natural predator insects in an artificial rearing box, in advance, until the amount of the natural predator insects reach an amount required for growth to effective density in a third process after a second process, (2) a second process for releasing and breeding insects artificially grown in the greenhouse by the first process, and (3) a process for making the natural predator insects propagate up to the effective density and making the natural predator insects prey on insect pests that live in greenhouse.
