Another Soybean Aphid Update

July 24, 2003

Echoing Kevin's thoughts, I note that from time to time updates of pest situations or crop development occur right before issues of the Bulletin go to print, and even when he and Mike are out of town. Doris Lagos of Dr. David Voegtlin's lab, Illinois Natural History Survey, reported a soybean aphid catch of 131 aphids in the Dekalb suction trap last week. As stated earlier in this issue, aphid densities in soybean fields have been very high in northern Illinois. The capture of winged adults (alates) is an indication of aphid dispersal. A flight such as this is another reminder to continue monitoring soybean aphid densities and keep an eye on previously uninfested soybean fields.--Kelly Cook
