Trap Catches Identified to September 15

Greetings!

Welcome to the Aphid Alert update for the week ending September 15. We are winding down the season with only 4 sites reporting and only 13 total vector aphids captured. Most sites have closed down and I expect that next week will be our seasonal summary.

Although few aphids were captured this week, 2 sites reported Green Peach Aphids (2 from Brooks MN and 1 from Tappen ND). Otherwise only several other vector species were recovered from the traps.

While there was very little additional Vector pressure added this week, the season's cumulative PVY Vector Risk was very high for the 2017 season.
