Aphid Alert (July 14)

Looks like it might be turning into an aphid year. We saw high trp catches at some locations this week and we're seeing a lot of diversity in the species being captured. Six sites this week had trap catches containing more than 20 vectors of varying efficiencies: Humboldt (35), Ada (41), Crookston (49), Sabin (25), and Brooks (39) in MN and Hoople (26) in ND. However, Green peach aphid (the most efficient vector) was recovered from traps in Perham, Crookston, Sabin, and Brooks.
