本文通过在三个不同地区采集同是寄生在甘蔗条螟卵上的同种螟黄赤眼蜂,进行杂交试验,并在人工寄主卵上进行抗病力测定,在柞蚕卵上繁殖作卵粒寄生率和卵粒羽化率比较,以红旗蜂最好。说明不同地区来源的同种螟黄赤眼蜂,在人工繁殖力,特别卵粒羽化率上存在明显的差异,为人工大量培养同种螟黄赤眼蜂的蜂种选育和标准化生产,提供了重要的理论依据。 In this paper, we collected the same Trichogramma dendrolimi parasitized on the eggs of C. saccharum in three different regions to carry out the hybridization test and determined the disease resistance of the artificial host eggs to breed on oak eggs Parasitization and emergence rate of eggs compared to red flag was best. It is indicated that there are obvious differences in the artificial fecundity and the emergence rate of special eggs in the same species of Trichogramma from different regions, An important theoretical basis.
