| 六斑平颜蚜蝇Eumerus seximaculatum Huo et Liu是一种对肉苁蓉造成毁灭性危害的蛀茎害虫，本研究旨在探索温度对六斑平颜蚜蝇生长发育及繁殖影响，为其预测预报和防治提供依据。在室内测定了六斑平颜蚜蝇在16、20、24、28和32±1℃ 5个恒温处理下各发育阶段的发育历期、存活率、繁殖力以及种群增长指数。结果表明，在16~32℃恒温范围内，六斑平颜蚜蝇均能完成整个世代，各虫态的发育历期随着温度升高逐渐缩短；而存活率、繁殖力、种群增长指数随着温度升高先增多后减少。28℃时世代存活率、每雌平均产卵量、预计下一代产虫数、种群趋势指数均最大，分别为66.67%、150.77粒、2 277.25头、34.68,说明28℃为六斑平颜蚜蝇种群增长的最适宜温度。 |
| 英文摘要: |
| The Cistanche deserticol stem borer, Eumerus seximaculatum, is a devastating pest, causing severe damage to Cistanche deserticol industry. In this study, the effects of temperature on the growth, development and reproduction of E. seximaculatum were studied in order to provide the basic information for prediction and prevention. The developmental duration，survival rate and population trend index of E.seximaculatum were measured under 5 constant temperature. The results showed that the whole generation could be completed and the duration of different developmental stages was gradually shortened as the temperature rose, but the survival rate, fecundity and population trend index increased first, and then decreased with the increase temperature within the constant temperatures ranging from 16 to 32℃. At 28℃, the generation survival rate, the average number of eggs per female, estimated number of adults of next generation, and the population trend index were all the largest, which were 66.67%, 150.77, 2 277.25 and 34.68 respectively. It indicates that 28℃ is the optimum temperature for the population growth of E. seximaculatum. |
