Soybean aphids discovered early, but may not be a big worry

Soybean aphids have been rearing their ugly heads since late June, but the early infestations may not be a bad thing.  The pests have been detected in South Dakota soybean fields and elsewhere, according to Adam Varenhorst, extension entomologist at South Dakota State University.  The discoveries are common among several soybean producing states.

“The important side note is that although we can find aphids in a lot of these fields, we’re finding very small populations and they’re on just a few plants within the fields,” Varenhorst told Brownfield Ag News.

The good news is that early appearing aphids may not grow to economically important numbers because they may be confronted by natural enemies, said Varenhorst.

“Lady bugs and other insects will actually eat the aphids.”
