More psyllids found; one Lso positive psyllids captured last week

ByTasha Stanzak Potato Psyllid/Zebra Chip Monitoring Program
  • This week we received traps from all 55 fields that we are monitoring.
  • We captured a total of 72 psyllids spread across 28 fields.
  • Captures were from the following counties: Owyhee, Canyon, Elmore, Gooding, Jerome, Twin Falls, Minidoka, and Cassia.
  • Of the 42 psyllids captured last week, one from Twin Falls County tested positive for Lso.
  • For psyllids captured this week, we expect to have results on Lso incidence next week.

Psyllid captures this week were higher than at this time last year, though Lso incidence is still relatively low at this time. Psyllid captures appear to be creeping up a bit, which is not surprising given the high temperatures and the time of the season. Overall captures this year have so far tended to be higher than for the last four years, but still not nearly as high as some prior years. Risk of ZC so far looks to be moderate to low.
