Aphid Alert
Welcome to the Aphid Alert update for the week ending September 08. The colder weather has brought along at least one good thing, the aphid vector numbers took a real tumble this week. With only 6 sites reporting this week, only 34 vector aphids were recovered from across the area (that number was 244 last week!) Only one site had vector numbers in the double digits; Humboldt reported 12 vector species (compared to 93 last week). No Green Peach Aphids were recovered in the past week and Soybean Aphid numbers likewise were much lower.
