摘　　要：从过寄生角度探究了不同蜂卵比例繁育螟黄赤眼蜂对其品质的影响。对以卵卡面积作为不同蜂卵比例繁殖的种群自身出蜂数量、喂食对其寄生率及其后代性比的影响、不同卵龄米蛾卵的寄生率和后代性比等3个方面进行比较研究。结果显示,不同接蜂比例繁殖的螟黄赤眼蜂,接蜂比例越大,过寄生现象越严重、虫体越小、雌性比越低、单位面积出蜂量也越少。本品系螟黄赤眼蜂接蜂比例应在1∶6与1∶10之间,以接近1∶10为宜。Effects of superparatisim on quality of massive rearing of Trichogramma chilonis by inoculation proportion between parasitoids（T. chilonis） and host eggs were studied in laboratory. The results showed that superparasitism had significant effects on qualities of T. chilonis. As inoculation proportion between parasitoids and host eggs and frequency of superparasitism increased, body size（based on length of hind tibia）, sex ratio of female offspring and numbers of emerged adults reduced. Therefore, inoculation proportion of parasitoids and host eggs should be ranged from 1 ∶6 to 1 ∶10, and optimal proportion was 1∶10.
