Soybean aphid remains a significant pest of soybean in parts of the north central U.S.
Recent development of insecticide resistance in this pest creates a new challenge for
soybean production. Multiple lines of evidence, including reports of field level
failures, and data from replicated efficacy trials and laboratory bioassays, that
indicate that some populations of soybean aphid from Minnesota, North Dakota,
South Dakota, Iowa and Manitoba have developed resistance to some pyrethroid
insecticides (bifenthrin and lambda-cyhalothrin).
