The first aerial black fly (gnat) suppression operation of the 2017 season will be conducted Thursday, April 20 on the Juniata River, Conewago Creek, Conodoguinet Creek, Sherman Creek and Tuscarora Creek starting at 0700. The operation will start in Adams and York Counties and move up the Juniata River and end in Huntingdon County. Flights will be conducted in Adams, York, Cumberland, Dauphin, Perry, Juniata, Mifflin and Huntingdon Counties. The helicopter treating the Juniata River and creeks will be a black Bell 206 Long Ranger with the tail numbers N651HA.
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.
