TB123: Experimental Application of B.t.i. for Larval Black Fly Control: Persistance and Downstream Carry, Efficacy, Impact on Non-target Invertebrates and Fish Feeding
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.https://digitalcommons.library.umaine.edu/aes_techbulletin/1083/thumbnail.jp
