Electrophoretic Patterns of Egg Proteins From Several Insect Taxa

Abstract

Can. Ent. 101: 1256-1265 (1969) Egg-protein patterns from 23 insect species representing seven orders were obtained by acrylamide gel electrophoresis. The patterns were species specific and highly reproducible. Those for congeneric species were very similar and family resemblances were apparent. The usefulness of egg-protein patterns in phylogenetic studies and in the analysis of closely related species was suggested.

A Comparative Study of the Haemocytes (Blood Cells) of Cockroaches (Insecta: Dictyoptera: Blattaria), With a View of Their Significance in Taxonomy

“…In direct contrast to this viewpoint, there are equal reasons to accept the haemocyte complex and features of its categories as criteria in taxonomy. Although insect diversity is recognized most easily through external morphological features and biological characteristics, it is clearly evident also in features of internal anatomy and in histological and chemical aspects of certain systems (Judd 1948; March 1972 Salkeld 1969;Gouin 1970). The haemocyte complex is distinctive for certain orders of insects (Jones 1962), and sometimes for species (Ritter 1965;Arnold 1971), but the significance of these distinctions and their reliability at other taxonomic levels require clarificatiob.…”
