摘要
1992年,以生命表技术比较了晒黄烟8个栽培品种对烟蚜的感虫性.结果表明,以净生殖率(R0)而言,小花青显著小于渔涝烟、湘潭香叶、湘潭漂叶、寸三皮、大宁旱烟等品种;而平均世代历期(T)、内禀增殖力(rm)及周限增长率(λ),则各晒黄烟品种间均无明显差异.以烤烟主要栽培品种中的感蚜住弱的NC-89及中感品种NC-60作对照品种,则小花青感蚜性与NC-60近似,其余晒黄烟品种则均较感蚜.
In 1992,
The sensitivity of aphids to eight uarieties of yellew sun-cured tobaccowas compared by using a
life table study. The results show that the sensitivity of Xiao Hua-qing tabacco is significantly
weak, whereas the parameters T,γm,λare nearly the same. Byway of contrast to NC-89 and
NC-60,the sensitivity of Xiao Hua-ging is almost the same asNC-60 , and the others , are weaker.
