psyllid captures continue to be moderate; no new Lso positives

• This week we received traps from 58 of the 58 fields that we are monitoring.
• We captured a total of 30 psyllids across 14 fields.
• Captures were from the following counties: Payette, Canyon, Gooding, Twin Falls, Minidoka, and Bingham.
• None of the psyllids collected last week tested positive for Lso.

Psyllid captures continue to be moderate. Captures this week were only slightly higher than what we found at this time over the last two years. Captures in the Treasure Valley and Upper Snake were similar to last week; captures in the Magic Valley ticked up only slightly relative to last week. We have captured a total of only 3 Lso-positive psyllids so far, which is lower than the Lso incidence we found at this time over the last few years. Typically we find the highest incidence of Lso in psyllids early during the season, so this low incidence so far is a good sign that overall Lso incidence for this season may be low.

Nevertheless, we urge growers across the state to have their IPM programs in place. More information on management can be found here:
