Psyllid captures tick up, no new Lso

• This week we received traps from 31 fields that we are monitoring.
• We captured a total of 43 psyllids across 14 fields.
• Captures were from Canyon, Gooding, and Twin Falls counties.
• Among the 14 psyllids captured last week, none tested positive for Lso.

Psyllid captures ticked up this week in both the Magic and Treasure valleys. This is not entirely surprising given that psyllid abundance very often spikes during August, though captures had been tracking much lower over the past several weeks. Thankfully all the psyllids from last week tested negative for Lso. Some fields have undergone vine kill and will no longer be monitored. Early harvest also limited person-power for trap retrieval from some sites, so those traps will be retrieved next week. We encourage you to maintain your IPM programs, especially in areas that have had higher captures of Lso-positive psyllids this season.
