| 中文摘要: |
| 为明确环境因子对云南蝠蛾蛹发育羽化的影响, 采用三元一次正交组合设计分析方法, 研究了不同土壤温度、土壤含水量、土层深度条件组合对云南蝠蛾蛹历期、羽化历期、羽化率、羽化出土率的影响, 并分别建立了回归方程。结果表明, 不同环境因子组合处理对云南蝠蛾蛹的发育羽化有显著影响, 其中以土壤温度16℃、土壤含水量60%、土层深度5 cm组合条件下蛹历期最短, 为18.41 d；羽化历期最短，为17 d; 羽化最为集中; 羽化率、羽化出土率结果最好, 均达到了96.67%, 在土壤温度8℃、土壤含水量30%、土层深度15 cm的组合条件下羽化率和羽化出土率均最低, 均为33.33%; 在土壤温度8℃、土壤含水量60%、土层深度5 cm的组合条件下蛹历期最长, 为36.75 d。从回归分析来看, 土壤温度对蛹的发育羽化起着主导主用, 特别是对蛹历期、羽化历期、羽化率的影响, 在这三个回归方程中, 其偏回归系数绝对值最高, 分别16.2、9.70、5.94; 土壤含水量对羽化出土率的影响起着主导作用, 其偏回归系数最高为75.42, 对羽化率的影响仅次于土壤温度, 而对蛹历期、羽化历期影响较小; 土层深度对蛹历期、羽化出土率的影响分别次于土壤温度、土壤含水量, 其偏回归系数绝对值分别为0.46、7.92, 对羽化历期和羽化率的影响最小。 |

| In order to clarify the effects of environmental factors on adult emergence of Hepialus yunnanensis, we studied the emergence rate, emergence percentage (soil surface), the pupal developmental duration and emergence duration of H. yunnanensis under the different combinations of soil temperature, soil moisture content, and soil depth by using orthogonal combination experiment and regression analysis of the three factors at different levels.The results showed that different combinations of environmental factors had significant effects on adult emergence of H. yunnanensis. Under the upper-level combination of three factors, the pupal developmental duration and emergence duration were the shortest (18.41 d and 17 d, respectively), while the emergence rate and emergence percentage (soil surface) were highest in all combinations (96.67%). Under the lower-level combination of three factors, the emergence rate and emergence percentage (soil surface) were lowest in all combinations (33.33%). The regression analysis indicated that the soil temperature played a dominant role in emergence rate, the pupal developmental duration and emergence duration, and the absolute value of partial regression coefficients of temperature were all the highest among the three equations (16.2, 9.70 and 5.94, respectively). Soil moisture played a dominant role in emergence percentage (soil surface), with a partial regression coefficient of 75.42, and played a secondary role in emergence rate; there was least effects on the pupal developmental duration and emergence duration. The soil depth played a secondary role in the pupal developmental duration and emergence percentage (soil surface), with the absolute value of partial regression coefficient of 0.46 and 7.92, respectively, and there was the least effects on the emergence duration and emergence rate. |
