MSTRS^®BHFW
Pheromone mating disruption formulation for controlling Blackheaded Fireworm (Rhopobota naevana)

MSTRS® BHFW impedes the mating of the blackheaded fireworm moths in cranberry marshes. Deploy MSTRS® BHFW immediately prior to the first emergence of blackheaded fireworm moths in early summer (usually during the first week of June in Wisconsin).The MSTRS®BHFW dispensers must be attached to stakes within the crop at a height of 1.5 feet above the crop canopy, at a density of 7 - 10 dispensers per acre, depending on the size of the area to be treated. Dispensers are spaced every 25 yards around the perimeter of every 10 - 15 acre section of one or more cranberry beds. Transects must begin 100 yards from the edge of the 10 - 15 acre section. Further transects are made at 100 yard spacings.
The dispensers will emit effective amounts of pheromone for 60 days.
Treating larger areas gives a geometrical advantage in coverage of the cranberry beds by plumes of pheromone and reduces the number of dispensers per acre. Treating large areas also reduces the risk of mated females flying into treated areas from neighboring untreated beds.
