Spotted wing drosophila confirmed from Indiana and the United Kingdom - Update: SWD also found in Texas and Colorado

States where Drosophila suzukii, also referred to as spotted wing drosophila, has been detected in the continental United States. Adapted from Burrack, et al. 2012. Journal of Integrated Pest Management.

Spotted wing drosophila (SWD) was confirmed in Indiana during October 2012, bringing the total number of states with confirmed populations of SWD to 33.

SWD was also detected in United Kingdom in September 2012, which brings the number of countries (including the US, Canada, and Mexico) where SWD has been detected outside of its presumed native range of eastern Asia to at least nine.

Update, March 7, 2013
While reviewing the National Agricultural Pest Information System's (NAPIS) Pest Tracker records for spotted wing drosophila in preparation for an upcoming presentation, I noticed two additional state level detections for 2012 that I had previous missed, Texas and Colorado.  These detections bring the total number of states where SWD has been detected to 35 since 2008.
