Development of trapping methods to control stinging wasps (Hymenoptera: Vespidae)

ROUGH COPY:

Acetic acid with isobutanol was tested as potential attractants for social wasps.  These were tested across a grid versus perimeter placement, in order to develop and demonstrate the use of chemical lures for control of pestiferous yellowjackets.  While yellowjackets are beneficial predators of other insects, they need to be controlled when and where they constitute a threat to the health and safety of people and pets.  The main pest species in focus were the western and German yellowjacket (Vespula pensylvanica and Vespula germanica respectively).  It was found that - - - - - -.
