Invasive ants have received considerable attention due to their potential to change their environment e.g. by decreasing biodiversity. The European fire ant, Myrmica rubra was accidentally introduced into the
Initial field experiments examined 1). Ant recruitment to sugar baits with and without pheromone blend. 2). Ant recruitment to sugar bait alone compared to sugar bait with different doses of the pheromone blend. 3). Insecticidal bait removal with and without pheromone. Results showed no difference in ant recruitment to sugar baits with and without pheromones. Only one blend was significantly different from the sugar bait alone (P<0.017), although a trend of increased ant recruitment to all sugar baits with pheromones was observed. Approximately 14% more insecticide was removed from pheromone enhanced bait stations (P<0.043). These results demonstrate a trend of increased ant recruitment to bait stations with this ant alarm pheromone, continuing laboratory and field experiments will be conducted this summer for further investigation.
