| 摘 要： | 利用生命表法研究了一种人工饲料饲养的稻纵卷叶螟的生长发育和繁殖。结果表明,人工饲料饲养条件下稻纵卷叶螟幼虫能够完成生长发育并化蛹。幼虫历期28.1 d，蛹历期10.1 d, 较水稻离体叶片饲养分别延长6.1 d和1.7 d。成虫单雌产卵41.6粒，较离体叶片饲养增加26.2%。幼虫种群存活率曲线呈死亡率 年龄降函数，与离体叶片饲养差异不显著。实验种群生命表参数种群净增殖率、内禀增长力和周限增长率分别为17.6928、0.0884和1.0924，平均世代周期和种群加倍时间较离体叶片饲养增加4.9 d和 1.3 d，种群趋势指数为3.26，表明采用人工饲料饲养的稻纵卷叶螟种群数量呈上升趋势。

| Abstract: | The growth and reproduction of rice leaffolder,Cnaphalocrocis medialis,fed on an artificial diet were studied.The results showed that larvae were able to grow and pupate fed on the artificial diet.Durations of larva and pupa were 28.1 d and 10.1 d,respectively,6.1 d and 1.7 d longer compared with that reared on rice leaves.Number of ovipositions were 41.6 per female,26.2 percent higher than that fed on rice leaves.the survival rate of larva followed a descent mortality-age function,and was not significantly... |
