| 中文摘要: |
| 应用生命表技术研究了13、18、23、28和33 ℃温度条件下以菜豆为食物的牧草盲蝽的生长发育和繁殖情况。结果表明, 在13~33 ℃, 牧草盲蝽发育速率随着温度的升高而加快, 并符合Logistic模型;牧草盲蝽若虫、世代的发育起点温度分别为7.49 ℃和10.21 ℃, 有效积温分别为323.62日·度和393.7日·度; 在试验温度范围内, 23 ℃时牧草盲蝽的若虫期存活率最高(75%), 33 ℃时存活率最低(41%)。18~28 ℃为最适温区, 较低的温度(13 ℃)和较高的温度(33 ℃)不利于牧草盲蝽的存活。 |
| 英文摘要: |
| The laboratory populations of Lygus pratensis (L.) were studied at five different temperatures (13, 18, 23, 28 and 33 ℃) using life tables. The mirids were reared on Phaseolus vulgaris in the laboratory. The results showed that its development rate increased with increasing temperature and that the relationship between temperature and development rate could be simulated by a Logistic model. The developmental temperature thresholds and effective accumulated temperatures for nymphs and the whole generation were 7.49 and 10.21 ℃, 323.62 and 393.7 day-degrees, respectively. In the experimental temperature range, L. pratensis had the highest survival rate at 23 ℃ during nymphal stage (75%) and the lowest survival rate at 33 ℃ during the nymphal stage (41%). We concluded that the suitable temperature range is 18-28 ℃ for L. pratensis. Lower temperature (13 ℃) or higher temperature (33 ℃) is not suitable for the survival of L. pratensis. |
