摘要
采用不同体长的松墨天牛的幼虫作寄主繁育管氏肿腿蜂时,较大的寄主能有效的降低松墨天牛幼虫在繁蜂过程中的干瘪率,提高了管氏肿腿蜂的寄生率和寄生成功率,且较大寄主上由于接蜂量大,相应地单位寄主上的产卵量和出蜂量都得到增加,从而有效的提高了管氏肿腿蜂的繁蜂效率。
Scleroderma guani were bred with different larval lengths of Monochamus alternatus.The results showed that bigger size of the host larvae could result in lower shriveling rate themselves during breeding process,thereby improve the parasite rate of of S.guani.Moreover,larvae with bigger size could breed more individuals of S.guani resulting in higher productivity per unit,hence improving the breeding efficiency.
