| 摘 要： | 利用体长为2．0～3．0cm的松墨天牛幼虫繁育管氏肿腿蜂和川硬皮肿腿蜂，分别按蜂虫比2：1．3：1和4：1接蜂．测定感染率、寄主干瘪率、寄生率、寄生成功率、产卵量和出蜂量等指标．结果表明：蜂虫比3：1处理组在繁育2种肿腿蜂时各项指标均最好，2种肿腿蜂在3个处理组的繁蜂效益产出比分别为1．00：1．98：1．36和1．00：2．79：1．49，故3：1的蜂虫比是比较适宜的．

| Abstract: | Scleroderma guani and Scleroderma sichuanensis were bred by utilizing 2.0 cm to 3.0 cm long larvae of Monochamus alternatus. The inoculation was conducted with three parasitoid-host ratios （2：1,3：1 and 4：1 ）, and the indexes such as infecting rate, shriveled rate of host, parasitical rate, successful parasitical rate, quantity of oviposition and the number of bethylid filial generation were determined. The results showed that 3： 1 parasitoid-host ratio was the best choice for breeding these two species of ethylids regarding to each index mentioned above. The breeding efficiency ratios of the two bethylid species were 1.00：1.98：1.36 and 1.00：2.79： 1.49 respectively. So the parasitoid-host ratio of 3：1 was thought to be the optimal ratio among the three treatments. |
