中文摘要: |
以廊坊市主要园林绿化树种白蜡(Fraxinus chinensis Rosb.)、法国梧桐(Platanus orientalis L.)、
桑树(Morus alba L.)、臭椿〔Ailanthus altissima(Mill.)Swingle〕、毛白杨(Populus tomentosa Carr.)和香
椿〔Toona sinensis(A. Juss.)Roem.〕为目标树种,2014 年9 月在其3 年生林地中进行美国白蛾〔Hyphantria
cunea(Drury)〕人工接种试验,并用目标树种的离体叶片饲喂美国白蛾幼虫,统计其食叶量,同时测定目标
树种非自然侵染前后可溶性蛋白质含量的变化。结果表明:美国白蛾对目标树种取食量的高低顺序为桑树>
法国梧桐>臭椿>白蜡>毛白杨>香椿;美国白蛾取食后,树种(抗性和感性)叶片内可溶性糖含量的变化
没有规律,抗虫性高低与可溶性糖含量的高低没有对应关系。 |
英文摘要: |
In September 2014,the experiment of factitious infection by Hyphantria cunea(Drury)
(Lepidoptera:Arctiidae)was carried out in three-year woodland of target tree species,including Fraxinus
chinensis Rosb.,Platanus orientalis L.,Morus alba L.,Ailanthus altissima(Mill.)Swingle,Populus tomentosa
Carr.,Toona sinensis(A. Juss.)Roem in Langfang City. The larvae of H. cunea were reared on leaves of the target
species under laboratory conditions,and their leave consumption and changes of soluble sugar content of target tree
species before and after factitious infection by H. cunea were measured and compared. The results indicated that the
order of leave consumption by H. cunea arranged as M. alba > P. orientalis > A. altissima. > F. chinensis > P.
tomentosa > T. sinensis. There was no regularity of change of soluble sugar content in target tree species(tolerant
and susceptible to the moths). The results demonstrated that the resistance to H. cunea was insignificantly correlated
with soluble sugar content. |
