First detection and widespread distribution of the spotted wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), in Connecticut in 2011.
The non-native spotted wing drosophila, Drosophila suzukii (Matsumura), was first detected in Connecticut in August 2011. In a subsequent survey, conducted between September and December 2011, the eastern Asian D. suzukii was found in 86 (50.9%) of 169 municipalities distributed in the eight counties of Connecticut. New distributional records were based primarily on capturing adults in vinegar-baited traps and on rearing them from infested fruit. During the survey, adults were reared from fruit on wild plants of Elaeagnus umbellata Thunberg, Phytolacca americana L., and Vitis labrusca L. and on cultivated plants of Ampelopsis brevipedunculata (Maximowicz) Trautvetter, Cornus kousa Hance, Diospyros virginiana L., Rubus idaeus L., and Vaccinium corymbosum L. Wild hosts of D. suzukii should be considered when management programs are designed and when population growth is modeled.
