In the summer of 1985 a field experiment was conducted in the Sugarloaf area of Maine on the use of B.t.i. to reduce the numbers of black fly larvae in the Carrabassett River and a tributary stream. The objectives were to determine the rate of application necessary to produce an acceptable reduction in black fly larvae, to study the fate and persistence of B.t.i. in a stream following application, to determine the impact of B.t.i. on the abundance and drift of non-target stream insects and on the feeding success and diet composition of fishes in the treated streams.
