Rothamsted suction trap captures – week ending 29 June

The most recent bulletin has just been released 2014webbulletin13.pdfahdb20aphid20news2020140704-2.pdf.

During the week ending 29th June, unsettled weather with thundery showers at the weekend provided few opportunities for any significant increase in aphid flight activity.

• Numbers of the peach–potato aphid (Myzus persicae) are starting to fall in central and eastern England. The first individual has been caught in the suction-trap at Elgin.
• The potato aphid (Macrosiphum euphorbiae) was caught in low numbers at six sites.
• The pea aphid (Acyrthosiphon pisum) has been caught at nine sites with a hotspot at Writtle. Field reports indicate threshold levels are being reached in some parts of southern England.
• The cabbage aphid (Brevicoryne brassicae) was caught at seven sites in central and southern England, with a hotspot at Writtle.
• The number of the willow carrot aphid (Cavariella aegopodii) is now very low.
• The black bean aphid (Aphis fabae) was caught in seven suction traps this bulletin week with a hotspot at Writtle (18)
• Single currant-lettuce aphids (Nasonovia ribisnigri) were caught at 5 sites.
