High Soybean Aphid Populations Not Expected To Overwinter Into 2018

Producers gathered in Brandon this week for Manitoba Pulse and Soybean Growers' (MPSG) 2018 Crop Production Meeting.
Production Specialist Cassandra Tkachuk was part of a discussion surrounding soybean aphids.
She says just because aphid numbers were high in 2017, that doesn't mean they'll carry over to this upcoming growing season.
Tkachuk cited information provided by John Gavloski of Manitoba Agriculture.
"Basically since 2001, we've only had four years we had really high economic levels of soybean aphids, and actually these years did not coincide back-to-back, which speaks to the fact that they do not overwinter here," explained Tkachuk. "In addition to that, we do have data from the U.S. that has shown soybean aphids don't overwinter in Manitoba, or if they do, it would be very low levels."
