Abstract

Esterase-based resistance in the peach-potato aphid, Myzus persicae (Sulzer) is generally due to one of two alternative amplified carboxylesterase genes, E4 or FE4. The E4 amplified form is distributed worldwide and it is correlated with a particular translocation between autosomes 1 and 3, whereas the FE4 form, which has hitherto not been found to be associated with chromosomal rearrangements, is typical of the Mediterranean regions. In this study we present for the first time cytogenetic and molecular data on some M. persicae parthenogenetic lineages which clearly show a chromosomal A1-3 translocation associated with esterase FE4 genes and unrelated to high levels of esterase-based resistance.
