Psyllid captures increase – 24 July 2025 update

• This week we received traps from 48 fields that we are monitoring.
• We captured a total of 38 psyllids across 13 fields.
• Captures were from the following counties: Payette, Canyon, Jerome, Gooding, and Twin Falls.
• Among the 13 psyllids captured last week, none tested positive for Lso.

Psyllid captures this week ticked up from last week and were slightly above what we have seen during this period in the last three seasons. This is not entirely surprising given the high temperatures, and captures are still not anywhere near our highest capture years. ZC risk still appears to be fairly low this year.
