COMPARATIVE STUDIES ON BEHAVIOR OF 3 SPECIES OF ANTS (HYMENOPTERA - FORMICIDAE) .2. TRAIL FORMATION AND GROUP FORAGING

Methods of trail formation and organization of group foraging by the ants Formica obscuriventris Mayr, Myrmica americana Weber, and Crematogaster lineolata (Say) were studied under laboratory conditions. Each species was able to organize group travel to a persistent food source. M. americana and C. lineolata achieved this by using trail pheromones, the former species using these pheromones only to establish the trail and the latter using them in all stages of foraging. F. obscuriventris apparently did not use trail pheromones and each individual learned the route to the food independently. © 1969, Entomological Society of Canada. All rights reserved.
