Rothamsted suction trap counts

The latest aphid bulletin has just been released 2014webbulletin26.pdf together with a new issue of AHDB Aphid News ahdb_aphid_news_20141003.pdf.

The very large number of "Indian summer" insects in the suction-traps and the diversity of aphid species have meant that the identification team have been unable to deal with all samples again this week. The same is likely to be true next week as they will be looking at samples collected from last Monday to the coming Sunday. With a return to more typical weather, numbers trapped in the coming week are likely to drop somewhat.
