Location: Imported Fire Ant and Household Insects
Project Number: 6615-32000-044-13
Start Date: Jul 01, 2010
End Date: Jun 30, 2015
1) Monogyne laboratory colonies will be derived from newly mated queens or from excavated colonies from the field. Colonies will be housed in large boxes that can be connected with bridges allowing contact between to different colonies. Treatments will be sustained release recruitment pheromone uniformly distributed on the foraging surface. Two colonies – one treated and the other a control will be bridged to a common foraging area. The dynamics of this competitive arrangement will be observed at least three times a day. The results will determine if the treatment confers a disadvantage, no advantage, or an advantage to the treated colony. Trailing events will be recorded and colony size (brood/workers/presence of a queen will be periodically monitored as measures of colony health. 2) Monogyne field sites will be selected and manipulated by eliminating surrounding colonies so that target colonies have a well defined territory. The sustained release formulation of the fire ant recruitment orientation pheromone will be evenly distributed over the target colony territory and challenged systematically and over time with baits to determine their recruitment capabilities. and the longevity of the sustained release formulation. Colony size will be monitored weekly using mound size and a population index measure. Brood production will be aslo measured weekly as a gage of queen productivity.
