Trap Catches Identified to September 4

Greetings!

Vector numbers and PVY risk have dropped dramatically from the past two weeks.  Still seeing some bird cherry oat and soybean aphids but in much smaller numbers.  Ada led the sites with a PVY Risk of 3.15, down from 12.81 lasat week.  All other sites reporting index values below 2.0, many below 1.0.  

We've had fewer sites reporting as some are beginning to vine kill and harvest.  We will continue to report as long as we get traps in!  Good luck out there!

Trap Catches Identified to 8-31

Greetings!

It looks like the cooler weather has begun to decrease aphid numbers.  We are reporting two weeks worth of data for the Hatton and Tappen sites, and in each case there is a significant reduction in total vectors and PVY risk.  Green peach numbers are down and soybean aphids have dropped dramatically in all locations except Ada.
