Extract

On 15 November 1971, during collection of galled balsam fir needles from two experimental plots in Edinburg, Maine, damaged galls were noted. The galls had obviously been torn open (Fig. 1). Since this was not recorded in the literature and damaged galls were numerous, the situation was evaluated.
