Soybean aphid numbers continue to be low and aphids were observed in only 22% of the soybean fields scouted last week, mainly in MN. Grasshoppers are increasing and in mixed nymph-adult stages. Trap captures for banded sunflower moth and Arthuri sunflower moth increased this last week.
Despite relatively low sugarbeet root maggot (SBRM) fly activity at this time, the anticipated streak of hot weather is likely to produce major surges in fly emergence and subsequent movement into beet fields in the next couple of days.
With warmer temperatures occurring in most of North Dakota, flea beetles will be more active in areas with emerged canola fields.
