Aphid Alert, September 1 2015
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.
PVY-Vector Risk Index values reflect the weekly trap trap catch. Cumulative season PVY-VRI values are nearing those of last year in some locations.
For the whole story and detailed catch information, as well as the PVY-VRI maps check out: aphidalert.blogspot.com

Thanks to Dr. Ian, Nate, and their crew for all the hard work on the Aphid Alert!
