An aerial black fly suppression operation has been scheduled for Thursday May 10 and Friday May 11 on the North Branch of the Susquehanna River, Main Stem Susquehanna River, the Juniata River, the Chemung River and Fishing Creek.  This operation will begin in Bradford County Thursday at 0700am and move south ending on Friday. This aerial application will include flights in Bradford, Wyoming, Lackawanna, Luzerne, Columbia, Montour, Snyder, Union, Northumberland, Perry, Juniata, Mifflin, Dauphin, Cumberland, Lancaster and York Counties. 

The helicopter will be a Bell 205 with the tail number N638HA and is painted red with yellow striping.

Helicopter Applicators Inc. will be dispersing Vectobac SC, which is a Bti product manufactured by Valent Biosciences.  Bti is short for Bacillus thuringiensis var. israelensis, which is a bacterial larvicide, not a chemical, and is the only product used in Pennsylvania's waterways for black fly suppression.  Vectobac SC is a thick brown liquid resembling chocolate milk.  The helicopter will fly low near tree top level and release the Vectobac SC at various predetermined positions on each stream.  .
