| 中文摘要: |
| 为了明确温度对苹果蠹蛾生长发育的影响，在室内15、20、25、28、31、34 ℃条件下，测定了苹果蠹蛾各发育阶段的历期，利用Marquardt法拟合推导出苹果蠹蛾的发育起点温度与有效积温。结果表明，在15~31 ℃范围内，苹果蠹蛾各阶段发育历期随温度的升高而缩短，但是当温度达34 ℃时，苹果蠹蛾发育速率变慢，各阶段发育历期出现较为明显的延长现象，各虫态死亡率大幅增加，已接近苹果蠹蛾存活的上限；苹果蠹蛾卵、幼虫、蛹和整个未成熟期的发育起点温度分别为10.64、10.68、9.33、10.41 ℃，有效积温分别为75.46、293.57、147.63、508.86日•度。说明温度对苹果蠹蛾生长发育有显著的影响，高温对苹果蠹蛾的生长发育具有明显的抑制作用。 |

| The effects of temperature on development of the codling moth, Cydia pomonella (L.) was studied. Under the conditions of 15 ℃, 20 ℃, 25 ℃, 28 ℃, 31 ℃ and 34 ℃ in the laboratory, we investigated the developmental durations of each life stage of the codling moth, and then fitted the threshold temperature and effective accumulated temperature by Marquardt. The results showed that the developmental durations decreased with the temperature increasing from 15 ℃ to 31 ℃, but the developmental durations obviously increased at 34 ℃. At the same time, the mortality increased drastically; the developmental threshold temperature for eggs, larvae, pupae and overall immature stages of the codling moth were estimated to be 10.64 ℃, 10.68 ℃, 9.33 ℃, 10.41 ℃, and the effective accumulated temperature for these stages were assessed as 75.46, 293.57, 147.63 and 508.86 degree days, respectively. It indicated that the influence of temperature on development of the codling moth was remarkable, and high temperature significantly inhibited the development of the codling moth. |
