Abstract: In order to guide soybean production and insect resistance breeding,this study investigated the occurrence dynamics of soybean pod borer in Heihe Region in 2021,analyzed the resistance of soybean pod borer of10soybean varieties mainly planted in Heihe Region,and evaluated the resistance of soybean varieties to insect pests comprehensively by cluster analysis of pod decay rate and insect feeding rate.The results showed that the emergence period of adult soybean pod borer in Heihe Region lasted for 12days from the end of July to the beginning of August in 2021.Five varieties with high resistance to soybean pod borer were screened,which were Beidou 47,Heihe 43,Heike 60,Zhonghuang 911and Heike 68.Three insect resistant varieties were Jinyuan 73,Heike71and Heihe 53respectively.The high resistance varieties screened out could be used as the parents germplasm resources in the breeding of resistance to soybean pod borer in Northern Heilongjiang Province.
