Zaprionus indianus (Gupta) (Diptera: Drosophilidae), an invasive vinegar fly, was found for the first time in Adams County, Pennsylvania, in 2011. It was found in a commercial tart cherry orchard using apple cider vinegar (ACV) traps that were monitoring another invasive vinegar fly, the spotted wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae). Coincidentally, the first record of D. suzukii found in Pennsylvania was also found in this same cherry orchard only 3 months earlier as part of a spotted wing drosophila survey effort in raspberry, blackberry, grape, and tart cherry in Adams County. These same crops plus blueberry and tomato were monitored again in 2012. In this article, adult Z. indianus captures in ACV traps and other traps deployed in the aforementioned crops during 2012 season are presented and the economic importance of Z. indianus is discussed.
