| 摘 要： | 白蜡吉丁啮小蜂是蛀干害虫白蜡窄吉丁的重要寄生性天敌，寄生于寄主幼虫的体内，为人工聚殖和应用于生物防治，在7个温度梯度下观测了白蜡吉丁啮小蜂蛹的发育速率，并应用“最小二乘法”测得该小蜂蛹期的发育起点温度为（16．823±1．381）℃，有效积温为（78．851±0．442）日度。 |

| Abstract: | Tetrastichus planipennisi is an important natural enemy of Agrilus planipennis, a ruinous pest to Fraxinus spp.. In this paper, the effective accumulated temperature and threshold temperature for pupal development of T. planipennisi was reported, which were 78.851 ± 0. 442 degree - day and 16. 823± 1. 381℃ respectively. These data were important in mass - rearing the wasp for biological control for the emerald ash borer. |
| Keywords: | Tetrastichus planipennisi Threshold temperature Effective accumulated temperature |
