Psyllid captures increase a bit; no new Lso positives

• This week we received traps from 52 of the 58 fields that we are monitoring.
• We captured a total of 40 psyllids across 11 fields.
• Captures were from the following counties: Payette, Canyon, Owyhee, Elmore, and Twin Falls.
• None of the psyllids collected last week tested positive for Lso.

Psyllid captures increased this week to their highest level overall this season; however, captures are still relatively low and similar to the season-long totals from last year. Thankfully, no new Lso-positive psyllids were collected last week. Although psyllid captures have been relatively low this season, Lso incidence was slightly higher than in most recent years, which may slightly elevate risk of ZC. Please maintain you IPM programs, especially in areas with higher captures of Lso-positive psyllids.

This is our last week of retrieving traps from the field and reporting on captures. Next week we will report on Lso testing results from the psyllids collected this week and wrap up the season.

Please maintain your IPM programs. More information on management can be found here:
