Abstract
SUMMARY Peach‐potato apbids, Myzus persicae (Sulz.), collected from six potato fields in western and central Scotland in 1976 were tested for aphicide resistance biochemically and by bioassay. Most aphids were resistant to organophosphorus insecticides. At five of the sites, some aphids were both highly resistant to organophosphorus compounds and moderately resistant to pirimicarb.
