摘要
在温度25℃、相对湿度70%±5%、每天光照16 h条件下,用富士苹果叶片饲养山楂叶螨,组建了山楂叶螨试验种群生命表。结果表明:在此条件下,取食富士苹果叶片的山楂叶螨整个发育历期为(8.7574±1.5080)d;种群的净增殖率为9.4362,内禀增长率为0.1105,周限增长率为1.1168,平均世代周期为20.3116 d,种群加倍时间为6.2725 d。
The life table of experimental population of Tetrancychus vienensis Zacher was established at constant temperature of 25 ℃, humidity of 70% ±5% and with illumination time of 16 hours in laboratory, with the leaves of Fuji apple feeding Tetrancychus vienensis Zacher. The results showed that the developmental duration of Tetrancychus vienensis Zacher was （8.757 4 ± 1. 508 9） d, the netreproductive rate was 9. 436 2, the instrinsic increase rate was 0. 110 5, the finite increase rate was 1.116 8, the mean generation cycle was 20. 311 6 d and the doubling time was 6. 272 5 d.
