Abstract: This study aims to explore the biological control measures of Leguminivora glycinivorella in Harbin by combining sex pheromone with biocontrol fungus in field tests. In 2023, the results of individual biocontrol measure tests suggested that lure A and Metarhizium anisopliae CQMa421 were more suitable than lure B and Beauveria basiana ZJU435, respectively, for controlling L. glycinivorella in Harbin. In 2024, the test results of sex pheromone combined with M. anisopliae revealed that the pod damage rate, seed damage rate and plant damage rate were all less than 36.17% when the sex pheromone traps of lure A were setup at 60 per hm2 before the borer adult emergence. The pod damage rate, seed damage rate and plant damage rate were significantly lower when the plants were sprayed with the low (600 mL/hm2) and high (1200 mL/hm2) recommended dosage of M. anisopliae CQMa421 on August 11 than when 75 g/hm2 of chlorantraniliprole was sprayed. There was no significant difference in pod damage rate, seed damage rate and plant damage rate and yield between the sex pheromone (lure A) combined with 1200 mL per hm2 of M. anisopliae CQMa421 and chlorantraniliprole, all being>78%. In summary, sex pheromone combined with M. anisopliae is prospective as a biological control measure for L. glycinivorella in Harbin.
