According to the method for obtaining the sterile male insects of the tomato leafminer, 137Cs-gamma rays are adopted for irradiation treatment of male pupae of the tomato leafminer to obtain sterile male adult insects of the tomato leafminer, the irradiation period is 2-3 days before eclosion, the irradiation dose is 200-300 Gy, the irradiation dose rate is 0.8-1.2 Gy/min, the irradiation time is 2-3 days before eclosion, the irradiation time is 2-3 days before eclosion, the irradiation time is 2-3 days after eclosion, and the irradiation dose rate is 0.8-1.2 Gy/min. The male imago obtained by the method can greatly reduce the survival rate of offspring while not influencing male imago eclosion and mating competitiveness, and can be used for prevention and treatment of tomato leaf miner. According to the tomato leaf miner control method provided by the invention, after a large number of irradiated sterile male adults of the tomato leaf miner are continuously released in the field, the sterile male adults compete with wild male adults to mate, so that the survival rate of offspring is greatly reduced, and the population quantity of the tomato leaf miner is effectively reduced.
