| 中文摘要: |
| 在5种温度下,对截形叶螨的发育起点温度和有效积温进行了研究。结果表明,截形叶螨不同发育阶段的发育起点温度和有效积温不同,且不同发育阶段对两者的要求也不一致。世代的发育起点温度和有效积温分别为13.88℃和137.41日度,控制发育进度的理论式为T=137.41/N+(13.88±2.00)。 |
| 英文摘要: |
| The developmental threshold temperature and effective thermal summation of Tetranychus truncatus Ehara were studied under five constant temperatures. The results showed that the developmental threshold temperature and effective thermal summation were different for different developmental stages, and the requirement for both were not identical for different developmental stages. The developmental threshold temperature and the effective thermal summation were estimated at 13.88C and 137.41 day degree for one generation. The theoretical formula of developmental rate control was T = 137.41/N +(13.88 + 2.00). |
