PSYLLID UPDATE FOR AUG 9

More potato psyllids were trapped this week in potato fields in Owyhee, Canyon, Ada, Elmore, Gooding, Jerome, Twin Falls and Cassia Counties. Over 200 psyllids have been collected in our monitoring network so far this summer, and only six have tested positive for Lso, the bacterium that causes zebra chip disease. Those six Lso positive psyllids were trapped in Canyon, Jerome, and Twin Falls counties. This is relatively low incidence (less than 3 percent) compared to last year. All psyllids trapped last week tested negative for Lso.
