The season is winding down with only 3 trap locations reporting this week.  Aphid numbers are decreasing in the reporting locations, harvest has begun.

Ada MN has had high aphid numbers for the entire season but vector numbers were down by half of last week's.  The trap at Crookston had lots of insects but no aphids, the Humboldt MN trap recovered only 5 vectors and 6 total aphids.  Corn Leaf, Cotton/Melon and Soybean aphids were the most common species recovered overall this week.

As always, keep on scouting!
