Aggression and Competition among Stingless Bees: Field Studies
1974
Johnson, Leslie K. | Hubbell, Stephen P.
Many species of stingless bees exhibit complex intraspecific and interspecific aggressive behavior towards each other when they meet on flowers or artificial baits. Such aggressive encounters significantly lower the amount of time that bees spend on food sources, as well as the amount of nectar or pollen which they can gather per visit. In addition, the intensity and duration of aggression at artificial baits rises sharply with increased sugar concentration. Different species vary markedly in inherent aggressiveness. Learning and recruitment appear to reinforce the effects of aggression on the spatial separation of foraging in competing colonies.
