Trap Catches Identified to August 24th

Greetings!

The downward trend continues, with even fewer aphids this week than last!

This week we recovered a total of 133 aphids, 117 of which were vectors. We did, however, only have 10 sites reporting. Of those sites, we saw the heaviest flights from Sabin (36) and Staples (21).  Soybean Aphid was moving last week, with 25 being captured between Crookston, Staples, Sabin and Ballard.  If you have soybeans still in a susceptible growth stage (younger than R6), keep your eyes open.  There was some good news for the trapping area - no Green Peach this week! However, Dr. Gloom (Dr. Neil Gudmestad) mentioned to us yesterday that there have been reports of Green Peach aphid in southern Minnesota and South Dakota.  We don't have any traps down in southern MN so we sadly don't have data - may need to install a couple of traps down there next year...  

Just because the year is winding down a bit, that doesn't mean that aphids are completely done wreaking havoc. Aphids will be active well into September, so unless you've vine-killed - you should still be scouting!
