在烤烟主栽品种的大田和盆栽植株上,连续3年用微笼关养的方法研究了烟蚜的生命表,以了解烟蚜的生殖力和死亡率.获得了净生殖率Ro,内禀增殖力rm,平均世代历期T及周限增长率λ等参数.试验结果表明,供试的12个烤烟品种中,烟蚜生殖力在NC89,G28,NC60品种上弱,在MC373,K326品种上较强,在Nicotiananesopltila,G70,6186品种上强,其他品种居中.不同年份间同一品种或不同品种间烟蚜的生殖力差异显著.烟叶中脯氨酸含量愈高和烟碱含量愈低的品种,烟蚜生殖力愈强.单位时间内烟蚜排蜜量愈多,刺食次数愈少的品种,愈适合烟蚜的生殖和存活.
The life table of aphids was studied in the field and potted plants of main cultivated flue-cured tobacco varieties for three consecutive years by micro-cage method to understand the fecundity and mortality of aphids, and the net reproductive rate (Ro) Prolongation period r, average growth period T and the growth rate of the cycle λ, etc. The results showed that the fecundity of Myzus persicae was weak in NC89, G28 and NC60 among 12 flue-cured tobacco cultivars tested, and in the varieties of MC373 and K326 On Nicotiananesopltila, G70, 6186, and other varieties were dominant.The fecundity difference of the same or different varieties was significantly different in different years.The higher the proline content and the lower the nicotine content The stronger the fecundity, the stronger the fecundity of the aphids was and the more the fecundity of the aphids per unit time was, the less the number of the ejaculation was, the more it was suitable for the reproduction and survival of the aphids.
