Heard from two credible sources that soybean aphids are on VC and V1 stage soybeans at London’s AAFC (North East side of London) as well as a few fields in Eastern Ontario and Southern Quebec. I will be doing a more thorough search this afternoon North of London too to see how widespread the aphids are colonizing in that area. No high numbers yet have been reported from any of these locations but it does look like soybean aphids are here and are attempting to colonize. Ladybeetles were already taking action at the London site.
