Spatial and temporal dynamics of Myzus persicae clones in fields and suction traps
1 The population of peach-potato aphid Myzus persicae in Scotland is comprised almost entirely of long-term asexual clones.
2 Over a ten year period, M. persicae from Scottish fields and suction traps were analysed with six microsatellite markers.
3 Out of 1497 individuals analysed, 14 clones (denoted A–N) comprised over 98% of the collection.
4 Some clones were particularly abundant but most clones had a widespread distribution on all available plants.
5 Clones E and L had distinct features in their distributions as clone L was geographically totally restricted to the north east of Scotland and clone E showed a marked preference for brassica crops.
6 Clones E and L provide direct evidence of a role for local adaptations in the distribution of M. persicae clones.
