摘　　要：中间寄主的营养状况是影响寄生蜂繁育效果的主要因素。对中间寄主进行处理以抑制其发育,保证其有充足的营养满足子代寄生蜂发育所需。本文研究了在0℃和2℃条件下中间寄主黄粉虫蛹体内营养物质蛋白质、总糖、海藻糖、糖原含量等随处理时间的先升高后下降的变化趋势,表皮硬化程度以及肿腿蜂的寄生率之间的关系。结果表明:寄生蜂寄生率与中间寄主体内营养物质含量呈正相关变化,与表皮硬化程度呈负相关变化。推荐2℃作为中间寄主处理的适宜温度,处理时间为24 h。The nutrition status of intermediate hosts is the main factor affecting the breeding effect of parasitic wasps. It is necessary to process the intermediate hosts in order to block the development, and to ensure that it meets the development of the offspring. Therefore, it is special significance to explore the suitable treatment temperature and time. Under the condition of 0°C and 2°C studying the relationship among nutrient substance of Tenebrio molitor pupae changes with time, such as p rotein, total su ga r, trehalose, glycogen increased first and then decreased, harden degree of intermediate hosts ？ cuticular layer and parasite rate of Scleroderma guani. It is clearly that the parasite rate of Scleroderma guani has a positive correlation with the content of intermediate hosts ’ nutrient substance, and has a negative correlation with harden degree of intermediate hosts ？ cuticular layer. In the end, it is advised that 2°C as the suitable temperature to treat intermediate host, and the time for treatment is 24 h.
