Aphid monitoring project update – July 22nd, 2013

Is the aphid flight collapsing or not?  Updating the winged aphid counts from my last report on July 5th, you can see in the Valley/Western region that there was a sharp drop in total winged aphids and strawberry aphid the week of July 8-12 but a partial rebound last week.
