A New Pest Concern in New England:
A new state record for Swede midge (Contarinia nasturtii Kieffer) was recently confirmed from an organic farm in New Haven County, Connecticut. A single adult Swede midge was captured by Dr. Kimberly Stoner (Connecticut Agricultural Experiment Station) on 27 July, 2006 in a Jackson trap placed in a field of mixed cruciferous vegetable crops.

Swede midge is a serious pest of cruciferous vegetables. In Europe, where severe crop losses have been reported, Swede midge is a common pest of crucifers, which include broccoli, cabbage, cauliflower, Brussels sprouts, kale, and collards. This exotic pest is also found in Southwestern Asia. It was first identified in North America in Ontario in 2000. In the U.S., Swede midge was confirmed in western New York in 2004 (U.S. record) and Massachusetts in 2005.Additional information can be found on the following websites:
