A few weeks ago we commented on the large number of soybean aphids being found on late season soybeans, especially in southern Ohio. This past week we have been finding, again with many other states, large numbers of aphids already on buckthorn, their over-wintering host. These large numbers of aphids suggest the potential of a large over-wintering population. Being that this summer has been considered a “soybean aphid year” in much of the eastern Corn Belt, we would normally expect that next year would be an off-aphid year. However, significant over-wintering could mean soybean aphid problems next year and perhaps an end to the two-year aphid cycle that we have been in since the aphid’s arrival. Growers should keep abreast through this C.O.R.N. newsletter on what happens this fall and then in the spring of 2010. As of now, we are seeing something unexpected that could lead to aphid concerns next summer. We will continue to modify our prediction for aphid problems next summer as conditions change.
