Title: The Relationship Between Voltinism Types and Main Characters of Asian Corn Borer in Jilin Province
Abstract: The relation between diapause and the rearing temperature,the post-diapause development duration of the inbred progeny and hybrid F1,and the pupation rate of the first generation in different ecological areas on the univoltinism types in the east and bivoltinism types in the west of Asian corn borer in Jilin province had been studied.Research result testified that development periods of the two voltinism types reared continuously were consistent,but the diapause rate was significant different after the rearing temperature reduced,and the diapause rate of univoltinism types were higher than of the bivoltinisms.Rearing progeny induced diapause of two voltinism types were still different in post-diapause development duration,the characteristic differences were similar to their overwintering generation.Differences of post-diapause development duration of hybrid F1 progenies between two voltinism types depended upon the parent interrelation in hybridization combination,differences of the post-diapause development duration were significant between hybrid F1 progenies of the positive and negative cross combination.Though there were differences in the pupation rate of the same voltinism types in three ecological areas of the east,central and west in Jilin province,there were remarkable differences in the pupation rate of two voltinism types in the same ecological area,and the pupation rate of the bivoltinism types was higher than of the univoltinism types.
