Written by Louis Nottingham and Katlyn Catron, August 9, 2021 Introduction Data showing efficacy of insecticides against leafhopper vectors of x-disease is still relatively sparse. To address this, we performed two lab bioassays to screen insecticide products against Colladonus montanus reductus, the most abundant leafhopper vector of x-disease found in Washington cherries. We evaluated insecticides […]
May 18, 2021 Prior to this project, there was no available experimental information on insecticide toxicity against the leafhopper X-disease vectors Colladonus Reductus and C. geminatus In 2020 we performed lab bioassays to screen various insecticide products against the most abundant of these two species in Washington cherries, C. reductus. Five insecticide materials achieved 100% […]
May 18, 2021 First Generation Adults are Starting to be Active First generation adults from leafhopper vectors of X-disease phytoplasma including C. reductus and C. geminatus started being found in traps the week of May 10, 2021. Generally, second generation leafhoppers are of higher concern as first generation leafhoppers are often controlled by your standard […]
March 10, 2021 Leafhopper Deterrence Linked to X Disease Management WSU entomologists and industry partners learn about X disease vectors to help the cherry industry optimize management. Work by the Nottingham lab on insecticide efficacy (“catching lots of wild leafhoppers and trying to keep them alive long enough to kill them”) and systemic insecticides applied […]
