Abstract

Esterase-based resistance in the peach-potato aphid, Myzus persicae (Sulzer) is\r\ngenerally due to one of two alternative amplified carboxylesterase genes, E4 or FE4.\r\nThe E4 amplified form is distributed worldwide and it is correlated with a particular\r\ntranslocation between autosomes 1 and 3, whereas the FE4 form, which has hitherto\r\nnot been found to be associated with chromosomal rearrangements, is typical of the\r\nMediterranean regions. In this study we present for the first time cytogenetic and\r\nmolecular data on some M. persicae parthenogenetic lineages which clearly show a\r\nchromosomal A1-3 translocation associated with esterase FE4 genes and unrelated to\r\nhigh levels of esterase-based resistance.
