Psyllid captures slightly lower than last week

ByErik Wenninger Potato Psyllid/Zebra Chip Monitoring Program
  • This week we received traps from 39 fields that we are monitoring; traps from several Treasure Valley fields will be picked up next week because of the Potato Association of America meeting this week.
  • We captured a total of 25 psyllids across 8 fields.
  • Captures were from Gooding and Twin Falls counties.
  • Among the 38 psyllids captured last week, 4 tested positive for Lso; all positives were from the Magic Valley.

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 several Lso detections in July to August) and ZC did not turn out to be a big problem.
