Trap Catches Identified to July 27th
Greetings!
We are seeing a continuing trend of increased vector pressure this week; 43 aphid vectors (from 13 different species) were recovered from 9 of the 13 sites reporting this week. Sabin and Ada reported the heaviest flights with 12 and 9 vector aphids respectively.
For the second week in a row, there were no Green Peach aphids collected. We are, however, still seeing flights of grain aphid species. Soybean aphids were recovered from the traps at Ada and Ballard (1 from each location), There have been hotspots of soybean aphids reported from fields in several locations, including Crookston (although no local fields have been reported over threshold). So keep monitoring for Soybean Aphids!

As always, keep on scouting!
