Abstract
An electrophoretic survey of genetic variability in 9 U.S. populations of the green peach aphid, Myzus persicae (Sulzer), revealed zero heterozygosity for 19 structural genes. This was contrasted with an avg heterozygosity of 0.07 for the potato aphid, Macrosiphum euphorbiae (Thomas), which has a similar life history. We propose that this finding reflects a recent, limited introduction of M. persicae, whereasM. euphorbiae is endemic. Several individuals, presumed to be morphologically similar species of Myzus, were detected both in natural and laboratory populations of M. persicae. Putative biotypes of M. persicae may be attributable to colonies derived from several species.This publication has 2 references indexed in Scilit:
