This is the final report of the 2025 potato psyllid / Lso monitoring season. Among the 11 psyllids captured last week, two tested positive for Lso, the bacterium associated with zebra chip disease (ZC). Overall captures have been remarkably similar for the last three years. About 10% of all psyllids tested positive for Lso this…
• This week we received traps from 21 fields that we are monitoring. Most fields have undergone vine kill and/or monitoring on them has otherwise ceased.• We captured a total of 11 psyllids across 3 fields.• Captures were from Canyon and Twin Falls counties.• Among the 17 psyllids captured last week, one tested positive for…
Psyllid captures were on par with the low-to-moderate numbers that we saw during the past few years at this time. Thankfully all the psyllids from last week again tested negative for Lso; we haven’t had any Lso-positive psyllids since early August. This should have been the last week of reporting on psyllid captures, but the…
• This week we received traps from 31 fields that we are monitoring.• We captured a total of 43 psyllids across 14 fields.• Captures were from Canyon, Gooding, and Twin Falls counties.• Among the 14 psyllids captured last week, none tested positive for Lso. Psyllid captures ticked up this week in both the Magic and…
• This week we received traps from all 48 fields that we are monitoring.• We captured a total of 14 psyllids across 8 fields.• Captures were from Owyhee, Canyon, Gooding, Jerome, and Twin Falls counties.• Among the 12 psyllids captured last week, 1 tested positive for Lso. Psyllid captures this week remained quite low, and…
• This week we received traps from all 48 fields that we are monitoring.• We captured a total of 12 psyllids across 5 fields.• Captures were from Payette, Canyon, Twin Falls, and Minidoka counties.• Among the 24 psyllids captured last week, 2 tested positive for Lso. Psyllid captures this week ticked down a bit from…
Psyllid captures this week were slightly lower than last week and similar to the moderately low captures we saw during this period in the last three seasons. Although we captured a few Lso-positive psyllids last week, the modest overall captures should mitigate ZC risk. We saw similar patterns last year (i.e., relatively low captures with…
• This week we received traps from 48 fields that we are monitoring.• We captured a total of 38 psyllids across 13 fields.• Captures were from the following counties: Payette, Canyon, Jerome, Gooding, and Twin Falls.• Among the 13 psyllids captured last week, none tested positive for Lso. Psyllid captures this week ticked up from…
Psyllid captures this week were similar to the relatively low captures during this period in the last 2-3 seasons. With relatively low psyllid captures and only two Lso-positive psyllids detected so far, ZC risk appears to be relatively low this year. That could change as the season progresses and temperatures rise, so stay tuned.
• This week we received traps from 47 fields that we are monitoring.• We captured a total of 9 psyllids spread across 8 fields.• Captures were from the following counties: Payette, Canyon, Jerome, Gooding, and Twin Falls.• The 3 psyllids captured last week all tested negative for Lso.• For psyllids captured this week, we expect…
