Aphid Alert Aug 11

Three locations topped 3 figures in vector counts this week (Ada at 217, Brooks at 173, and Humboldt at 205). The Humboldt site had a particularly high catch this week so if you're in the northern Valley, the aphids they are a movin'. Cereal aphids are starting to move out of grains and are being recorded in traps at high number, especially corn leaf aphids which are the most common vector species recovered from traps this year. Also numerous this week were soybean aphids, with a major trap catches in the northern RRV.
