Update from Rothamsted Insect Survey

The latest issues of the Rothamsted aphid bulletin and AHDB Aphid News have just been released: 2014webbulletin32.pdfahdb_aphid_news_20141114.pdf.
Aphid flight into crops (primary infection)
Numbers of peach–potato aphid are above average. If there has been good control of aphids to this point and they can’t be found in crops, the danger is probably passed.
Aphid movement within crops (secondary spread)
Conditions are still permitting aphid development, reproduction and movement within crops.
