摘要在实验室恒温条件下对柑橘弓翅目寄生蜂Lysiphlebia Mirzai Shuja-Uddin的发育、存活、寿命和繁殖进行了研究。幼虫在32℃下发育8.3d~20.3d，蛹发育在30℃下3.7d~15.4d，32℃下木乃伊未出成虫。幼虫期的最低发育温度和发育日数(DD)分别为3.70℃和142.7 DD，蛹期为4.8℃和94.2DD，幼虫期为6.2℃和181.2 DD。根据非线性生物物理模型确定了幼虫、蛹和幼虫联合发育的最适温度分别为30.3℃、33.3℃和31.1℃。蛹存活率在10~20℃范围内相对恒定(90~84.5%)。平均产卵量在25℃时为106.3粒，32℃时为41.8粒，成虫平均寿命随温度升高呈线性下降。在高温(37℃和40℃)和低温(5℃)条件下，幼虫的平均存活率随处理时间的延长而降低。在40℃下处理4小时后，成虫寄生蜂未能从木乃伊中冒出。此外，当取食蜂蜜和水时，成虫的平均寿命也会增加。米氏小蜂种群生长的最适恒温范围为15~25℃，这种寄生蜂在凉爽月份的防治效果可能比夏季更好。
Abstract Development, survivorship, longevity, and reproduction of Lysiphlebia mirzai Shuja-Uddin, a parasitoid of Toxoptera citricida (Kirkaldy), was studied at constant temperatures in the laboratory. Larval development ranged from 8.3 d at 32°C to 20.3 d at 10°C, and pupal development ranged from 3.7 d at 30°C to 15.4 d at 10°C. No adults emerged from mummies at 32°C. Duration of larval development was longer than pupal development. The respective low developmental temperatures and degree-days (DD) were estimated at 3.7°C and 142.7 DD for larval stage, 4.8°C and 94.2 DD for pupal stage, and 6.2°C and 181.2 DD for combined immature stage. The respective optimal temperatures of 30.3, 33.3, and 31.1°C for larval, pupal, and combined immature development were determined from a nonlinear biophysical model. The pupal survivorship was relatively constant within 10–20°C (90–84.5%). The average number of eggs laid per female in the initial 24-h period varied from 106.3 at 25°C to 41.8 at 32°C. The average longevity of L. mirzai adults decreased linearly with increasing temperature. At high (37 and 40°C) and low (5°C) temperature, the average pupal survivorship decreased as treatment time increased. Adult parasitoids failed to emerge from the mummies at 40°C after a 4-h treatment. In addition, the mean longevity of adult parasitoids was enhanced when they were fed with honey and water. The optimal constant temperature range for L. mirzai population growth was 15–25°C. This parasitoid may be more effective in control of brown citrus aphid in cooler months than in summer months.
