Trap Catches Identified to September 18, 2020.

The season is winding down with only 4 of 20 sites reporting this week.  Very few aphids were flying; the colder temperatures and field harvest decreasing their numbers.

Interestingly, green peach aphid was still recovered from one site.  It's late appearance this year indicates we may have had a very late in-flight to the region.  

Next week we'll be presenting a wrap-up of the season and summarizing the timing of aphid flights throughout the summer.  Here's hoping everyone's harvest goes well!

As always, keep on scouting!
