- This week we received traps from 58 of the 58 fields that we are monitoring.
- We captured a total of 21 psyllids across 11 fields.
- Captures were from the following counties: Payette, Canyon, Owyhee, and Twin Falls.
- Four of the psyllids collected last week tested positive for Lso.
Psyllid captures declined this week relative to last week. Captures overall continue to be moderately low and similar to the last two years. One Lso-positive psyllid was from Payette County, one from Elmore County, and two from Twin Falls County. Incidence of Lso usually diminishes over the season, though it is not unheard of to see a few positive psyllids in July to August. Thankfully overall captures have been relatively low this year, which should mitigate risk of ZC even with slightly higher Lso incidence in psyllids.
We urge growers 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
