Update on captures by Rothamsted suction traps
The latest edition of AHDB Aphid News has just been released and the most recent information about aphid captures is here - for captures in the week ending 12th June.
- Numbers of peach–potato aphids rose significantly with big hotspots at Wellesbourne (800) and Hereford (226) and high numbers generally across much of central England.
- The cabbage aphid was caught at 11 sites, with two discrete hotspots at Wellesbourne (1050) and Hereford (907).
- The willow ̶carrot aphid was caught at all sites, with numbers increasing at 11 sites and a big hotspot at Preston (818).
- The pea aphid was caught at ten sites, with numbers increasing at nine sites and a hotspot at Wellesbourne (98).
- Starcross continues as a very distinctive hotspot for black bean aphids, so far elsewhere it has been reluctant to visit the suction-traps.
- The currant-lettuce aphid (Nasonovia ribisnigri) was caught at Dundee and Kirton.
- Numbers of parsnip aphids increased, particularly at Preston (Cavariella pastinaceae at Preston 120, Wellesbourne 20, York 8 and Silwood 2; Cavariella theobaldi at Preston 20).
