Abstract	The Douglas-fir needle midge can be a very destructive pest of Douglas-fir. Infestation of new needles can be as high as 100 per-cent. Severe infestations can cause intolerable needle loss, and trees may take several years to recover. Needle loss is an especially serious problem in Christmas trees because of the aesthetic value of these trees. Published July 1994. Facts and recommendations in this publication may no longer be valid. Please look for up-to-date information in the OSU Extension Catalog: http://extension.oregonstate.edu/catalog
