Trap Catches Identified to June 21 - July 05

Greetings!

Welcome to the first edition of Aphid Alert for 2019!

We apologize for the late start this year, we had difficulties obtaining some of our supplies.

We had 4 traps responding in the first week of trapping, Crookston, Humboldt and Gully MN and Tappen, ND. We had significant captures of Damson-Hop and the closely-related Cannabis aphids last year.  Both are suspected vectors of PVY and so we'll be counting and reporting on both species this year.  

Other insect populations in potato are sporadic this season, with Colorado Potato Beetle numbers being very low in many locations.  But as plants have emerged in most locations and aphids are starting to fly, it might be useful to consider oil applications.

**NOTE - we mistakenly reported a trap return from Grenora last week.  Unusual, because Grenora hadn't yet started their trap! Turns out this was a vial from last year we had out for training purposes. OOPS!!
Corrected maps and data are below!!
