| 中文摘要: |
| 为了解桃小食心虫的潜在生命力，并为人工饲养桃小食心虫提供参考依据，在温度25（±1）℃、相对湿度80%、光照15 h条件下，对桃小食心虫的种群动态和繁殖动态进行观察研究，组建特定年龄生命表。结果表明：桃小食心虫的种群趋势指数为31.53，周线增长率为1.1102，内禀增长率为0.1045，净增值率为39.15，世代平均周期为35.25d，种群倍增时间为6.6325 d，在桃小食心虫蛀果之前防治是最佳时机。 |

| In order to explore potential vitality of Carposina sasakii Matsumura and provide reference basis for artificial feeding, the survival and multiplication rate of experimental population of C. sasakii Matsumura was observed under constant temperature of 25 (±1)℃, with humidity of 80% and illumination time of 15 h. The age specific life table was established. Experimental population parameters were obtained as follows: the index of population trend was 31.53, the finite rate of increase was 1.1102, the intrinsic increase rate was 0.1045,the net reproductive rate was 39.15, the mean generation time was 35.25 d, the doubling time was 6.6325 d. And the survial curve of C.sasakii Matsumura from the life table was drawn. The results showed that it was the best time to prevent them before C. sasakii Matsumura into apples. |
