Here's the catch for the catch period ending 7/25/2012.

Over all, numbers of aphid vector species recovered from suction traps were relatively low in most locations. Soybean aphid has not yet begun heavy dispersal flights but information provided by Bruce Potter on Lamberton suggests we may soon get some.  A large portion of this catch was cotton/melon aphid. Small grain aphids were less numerous with many grain fields already matured and/or harvested.
