Trap Catches Identified to August 17th
Greetings!
We recovered a total of 236 aphids, 206 of which were vector species. We're still seeing high diversity in the species captured, recovering aphids from 12 different aphid species from 15 of the 16 sites reporting. Hoople (42), Sabin (33), Ada (29), Gully (22), and the site in Nebraska (26) led the counts in trap captures this week.
Green Peach Aphids were up a bit this week (a total of 5 from 4 different locations) and the grain aphid counts remain high. Perham received a fair number of Soybean Aphids, suggesting they got a southerly or Southwesterly wind, bringing aphids up from the more heavily populated soybean fields in the south. The PVY Vector Risk Index remains low as the season wraps up. Here's hoping that transfers into a low PVY year!
As always, keep on scouting!
