非形态特征在粉虱分类中的运用（同翅目：粉虱科）

粉虱的分类主要利用第四龄幼虫 (蛹壳 )的特征而非成虫特征 ,而有的种类的形态有很大变异 ,完全依赖形态特征对某些种类 (特别是近缘种 )进行鉴定或鉴别是有困难的。因此 ,非形态特征的应用在粉虱分类中有一定的特殊价值。本文列举了一些可以用于昆虫分类的非形态特征 ,介绍了主要以非形态特征进行分类的特例——烟粉虱 Bemisia tabaci ( Gennadius)和银叶粉虱 Bemisia argentifolii Bellow &Perring的鉴别 ,并对非形态特征在分类中的合理运用进行了讨论。

Application of Non-morphological Characters in Taxonomy of Whiteflies (Homoptera: Aleyrodidae)

Taxonomy of whiteflies (Homoptera: Aleyrodidae) mainly relies on the morphological characters of the forth instar lavrvae (usually referred to as pupal stage or pupal case) rather than those of adults. However, difficulties arise in identification or distinguishment of some species (especially some sibling species) due to morphological variations in these species. Therefore, it is of significance, to some extent, to apply non morphological characteristics in whitefly taxonomy. Some non morphological characters are listed in this paper, followed by an example of their applications in distinguishing whitefly sibling species, Bemisia tabaci (Gennadius) and Bemisia argentifolii Bellows & Perring. Moreover, some aspects regarding proper ultilization of non morphological charaters in the whitefly taxonomy are discussed.
