The project implemented a systemic investigation to the pupa period of wild silkworm comparatively, which from Shanxi, Jiangsu, Sichuan, Chongqing, Guizhou provinces and so on. According to the investigation, the pupa dormant characteristic of Shaanxi wild silkworm was found, and the individual, which pupa period was more than two months was selected. Through the hybrid genetic analysis we found that the characteristics for a long period of pupa was controlled by polygene and genetic recessively and strongly influenced by environmental conditions at the same time. To compare the performance of pupa period of the pupa dormant wild mulberry silkworm, we designed different ecological conditions. The result indicating that the temperature is the main factor in the ecological impact, but the pupa period was extended at the same temperature conditions, indicating that the additive effects of the environmental factors.

本项目实施，系统调查比较了陕西、江苏、四川、重庆、贵州等省市的野桑蚕的蛹期经过，发现了陕西野桑蚕的蛹休眠特性，筛选获得了长达2个月以上的蛹期经过个体；通过杂交遗传分析，发现长蛹期特性表现为隐性遗传，受多基因控制，同时受环境条件的强烈影响作用；通过设计不同生态条件比较蛹休眠性野桑蚕蛹期经过的表现，表明温度是主要的生态影响因子，但相同温度的野外型条件下蛹期经过延长，表明受到环境因素的综合作用。
