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35.25 d,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 understand the potential vitality of peach moth, and to provide a reference for the artificial feeding of peach moth, the population dynamics and propagation of peach moth under the condition of 25 ℃ ± 1 ℃, 80% relative humidity and 15 h light were studied. Observation and research, the formation of a specific age table of life. The results showed that the population trend index of peach moth was 31.53, the weekly growth rate was 1.1102, the intrinsic rate of increase was 0.1045, the net increment rate was 39.15, the average generation period was 35.25 days, and the population doubling time was 6.6325 days. Gummy worms before fruit control is the best time.
