psyllid captures tick down; one more Lso-positive psyllid

  • This week we received traps from 57 of the 58 fields that we are monitoring.
  • We captured a total of 14 psyllids across 11 fields.
  • Captures were from the following counties: Canyon (2 fields), Owyhee, Jerome (2 fields), Twin Falls (4 fields), Cassia, and Bingham.
  • One more psyllid collected last week in Twin Falls County tested positive for Lso.

Psyllid captures have been ticking down slightly over the last two weeks. Captures this week were similar to what we found at this time over the last two years. So, after seeing moderately high captures at the start of the monitoring season, we are now seeing relatively low captures. We have captured a total of 3 Lso-positive psyllids so far, which is lower than the Lso incidence we found at this time over the last few years.

Nevertheless, we urge growers across the state to have their IPM programs in place. More information on management can be found here: https://www.uidaho.edu/extension/ipm/ag-pests/arthropods/psyllids
