摘要: 在室内利用玻璃双通管由中间寄主黄粉甲的初蛹直接接蜂繁育管氏肿腿蜂,比较不同蜂虫比对繁蜂效果的影响。结果表明,不同蜂虫比对管氏肿腿蜂单位虫重繁蜂量、子代蜂数量和雌雄比有较明显的影响,蜂虫比8:4时这几项指标达到最佳。蜂虫比对管氏肿腿蜂的发育历期有显著影响,且寄主数量相同时,管氏肿腿蜂子代蜂产卵前期随着蜂虫比的提高而缩短,发育总历期随着单管接种肿腿蜂数量的增多而缩短。综合以上各项指标,人工扩繁时采用8:4的蜂虫比最佳。

Abstract: Sclerodermus guani was bred with the prepupa of Tenebrio molitor by directly inoculating female parasitoid in a double-pass tube in the laboratory for evaluating the efficiency of different parasitoid-host ratios. The results showed that parasitoid-host ratios had obvious effects on the emerged number of filial generation per weight of T. molitor and sex ratios of S. guani, the most suitable parasitoid-host ratio being 8:4. The parasitoid-host ratio had significant effect on developmental duration, while at the same host density, the pre-oviposition period of filial generation was shortened with the increase of the parasitoid-host ratio and the developmental duration was reduced with the increase of the number of parental parasitoids inoculated in the double-pass tube. Therefore, 8:4 is the optimal parasitoid-host ratio when S. guani is bred with the prepupa of T. molitor.

Key words: Sclerodermus guani, Tenebrio molitor, mass rearing, parasitoid-host ratio
