摘要
通过对发生在吉林省的一、二化性玉米螟的繁殖能力研究得出，不同化性越冬代玉米螟的产卵期、成虫寿命、单雌产卵量和最大产卵量差异显著，一化性越冬代玉米螟的产卵量比二化性玉米螟高４５％以上。经虫体大小和重量比较得出，一化性越冬代玉米螟的蛹重比二化性玉米螟的蛹重高３５％以上，人工饲养的一化性玉米螟Ｆ_1代的蛹重也比二化性的蛹重高１０％左右。
Researches on the reproduction ability of overwintering generation adults in the two voltine ecotypes showed that the univoltine ecotype was superior to that of the bivoltine ecotype in the indias of oviposition period , adult longevity and amount of average and maximum eggs laid per female. The amount of eggs laid in the univoltine ecotype wasapproximate 45% more than that in the bivoltine ecotype. By comparing pupal weight of the two voltine ecotypes in overwintering generation , it was found the univoltine ecotype weighed approximately 35% more than the bivoltine ecotype,and the F_1 progenies of the univoltine ecotypes weighed approximately 10% more than the bivoltine ecotypes.
