The following information, dated July 7, comes from the University of Idaho.
Our official monitoring season began with wide deployment of traps last week and will continue for 10 to 12 weeks. We have 72 fields across the state this year, using four sticky traps per field at all sites.
This week we had traps deployed in 64 fields, though we are still waiting for traps to come in from three fields. We found a total of 12 psyllids across seven (11 percent) of the fields for which we have data. We have been monitoring three fields at the Kimberly Research & Extension Center since mid-May, and, interestingly, this week is the first that we have found potato psyllids. In previous years we nearly always captured psyllids here before the end of May.
Psyllids were captured in the following counties: Canyon (three fields), Owyhee (one field), Twin Falls (two fields) and Minidoka (one field).
We expect to have results on Lso incidence next week in addition to “heat maps” and additional details.
