This week we received traps from 46 of the 55 fields that we are monitoring. We captured a total of 29 psyllids across 13 fields. Nine of the fields were in Canyon County, the remaining 4 fields were in Payette, Owyhee, Gooding, and Twin Falls counties. Total psyllid captures were slightly higher than last week,…
This week we received traps from 53 of the 55 fields that we are monitoring. We captured a total of 21 psyllids across 9 fields. Six of the fields were in Canyon County, the remaining 3 fields were in Payette, Owyhee, and Twin Falls counties. Total psyllid captures were slightly higher than last week, but…
This week we received traps from 46 of the 55 fields that we are monitoring. We captured a total of 10 psyllids across 4 fields. Three of the fields were in Canyon County and one was in Twin Falls County. Total psyllid captures were similar to last week, and we continue to see relatively low…
This week we received traps from all 55 fields that we are monitoring. We captured a total of 14 psyllids across 10 fields. Seven of the fields were in Canyon County; the remaining 3 fields were in Owyhee, Twin Falls, and Minidoka counties. One of the psyllids we collected last week from Canyon County was…
The University of Idaho and our crop consultant collaborators across the state are once again monitoring for potato psyllids, zebra chip disease (ZC), and liberibacter (Lso), the bacterium associated with ZC. The monitoring program covers commercial potato fields throughout southern Idaho and is funded in part by the Idaho Potato Commission and generous in-kind contributions…
This is the final report of the 2022 potato psyllid / Lso monitoring season. The two psyllids captured last week tested negative for Lso, the bacterium associated with zebra chip disease (ZC). It was an interesting year with very low psyllid captures overall, but relatively high incidence of Lso. About 22% of all psyllids tested…
This week we received traps from 66 of the 72 fields that we are monitoring this year. We found a total of 17 psyllids across 11 (17%) of the 66 fields observed. Psyllids were captured from three fields in Canyon County on traps that had been deployed for two weeks. Psyllids were captured in the…
This is a turnip aphid, Lipaphis pseudobrassicae, a common aphid in the upper snake river plain (and across the country) that uses a wide variety of mustard family species as a secondary host. It is a known vector of PVY.
