本文报道中华草蛉(Chrysopa sinica Tjeder)用幼虫人工饲料(鲜鸡蛋40克、啤酒酵母30克、蜂蜜20克、蔗糖10克、抗坏血酸0.1克、水100毫升)和成虫人工饲料(猪肝粉10克、蜂蜜20克、啤酒酵母10克、水100毫升)连续饲养繁殖十个世代的试验结果。各代幼虫生长发育、结茧和羽化基本正常,成虫能大量产卵。一至十代幼虫平均结茧率为58.3—76.5%,平均羽化率为76.7—94.2%,成虫产卵前期为4—6天,平均产卵量为464.8—1561.7粒,其中一至三代平均产卵量均在千粒以上,最高的达2484粒,三代以后产卵量有下降趋势。
In this paper, Chrysopa sinica Tjeder was cultured on larvae artificial diet (40 g of fresh eggs, 30 g of brewer’s yeast, 20 g of honey, 10 g of sucrose, 0.1 g of ascorbic acid and 100 ml of water) G, honey, 20 grams, 10 grams of brewer’s yeast, 100 ml of water) for ten generations. All generations of larvae growth and development, cocoon and eclosion were normal, adults can lay eggs in large numbers. The average cocooning rate of first to tenth generation larvae was 58.3-76.5% with an average emergence rate of 76.7-94.2%. The pre-oviposition period of adult larvae was 4-6 days with an average of 464.8-1561.7 fecundity, of which the average fecundity of one to three generations All of them were over 1000 grains with the highest reaching 2484 grains, and the fecundity decreased after three generations.
