From Cathy Heidenreich, Extension berry specialist mcm4@cornell.edu
1 male and 1 female adult SWD were caught in an apple cider vinegar trap in a Yates County cherry orchard (non-fruiting) during the past week. This first confirmed 2012 trap catch comes much earlier than last year’s first confirmed catch on September 17, 2011, potentially placing summer raspberries and early blueberries at risk for possible infestations.
Growers should be monitoring for adults in small fruit plantings and keeping plantings as cleanly harvested as possible. For more information visit: http://www.fruit.cornell.edu/berry/pestalerts/drosophilapestalert.html
