Trap Catches Identified Week of Aug 15-19
Greetings
Another week of low numbers of aphid vector species in most locations. The exception was central and West Central Minnesota where traps in Staples and Verndale collected 23 and 52 respectively (mostly Bird Cherry Oat aphids), the Perham trap recovered 6 and the Sabin trap recovered 11 aphid vectors. Verndale and Sabin each had 1 green peach aphid in their catch this week and Crookston had 2. Soybean aphids were recovered in Sabin, Staples and Verndale as well, but not in excessive numbers. We have not yet seen a large flight of soybean aphids from the south and as the temperatures get lower and soybeans continue to mature, we may well soon be seeing decreased soybean aphid numbers.
But the catches in Central and West Central MN do indicate there's still aphids out there and much of our PVY is vectored later in the season. As always, keep scouting....
