AbstractCamponotus pennsylvanicus (De Geer) workers concentrate their foraging efforts in the vicinity of a new food source. Experiments with artificial “trees” confirm that these ants lay chemical trails when they locate food and under other circumstances. Marks left by ants travelling over smoked paper indicate that the trail consists of a series of streaks, sometimes variable in length, and that ants following trails make regular alternate deviations. Trails are laid extensively in the immediate vicinity of food. A trail is not reinforced by all gorged workers passing over it.The trails activate other workers and provide a means of orientation but are clearly non-directional. A bioassay with various organs indicated that the hind gut is the source of the trail substance.When a strong direct light is available, attention to trails dwindles and ants eventually use light orientation to reach the food, often following more direct routes at that time. Physical contact between workers may activate them but provides no directional information and may lead to temporary disorientation.

Do So

While it is generally accepted that honeybees ( Apis mellifera ) are capable of using the pattern of polarized light in the sky to navigate to a food source, there is little or no direct behavioural evidence that they actually do so. We have examined whether bees can be trained to find their way through a maze composed of four interconnected tunnels, by using directional information provided by polarized light illumination from the ceilings of the tunnels. The results show that bees can learn this task, thus demonstrating directly, and for the first time, that bees are indeed capable of using the polarized-light information in the sky as a compass to steer their way to a food source.

The Relationship

Interactions lie at the heart of social organization, particularly in ant societies. Interaction rates are presumed to increase with density, but there is little empirical evidence for this. We manipulated density within carpenter ant colonies of the species Camponotus pennsylvanicus by quadrupling nest space and by manually tracking 6.9 million ant locations and over 3200 interactions to study the relationship between density, spatial organization and interaction rates. Colonies divided into distinct spatial regions on the basis of their underlying spatial organization and changed their movement patterns accordingly. Despite a reduction in both overall and local density, we did not find the expected concomitant reduction in interaction rates across all colonies. Instead, we found divergent effects across colonies. Our results highlight the remarkable organizational resilience of ant colonies to changes in density, which allows them to sustain two key basic colony life functions, that is food and information exchange, during environmental change.

Biochemical Compositions

Biochemical compositions of black carpenter ants (Camponotus pennsylvanicus) were analyzed using standard methods. The proximate composition (%) were as follows: crude protein (22.50), crude fibre (1.46), carbohydrate by difference (30.86) and energy (35.4Kcal). The predominant mineral was potassium and nickel was the least. The antinutritional properties (mgkg-1) ranged as follows: Oxalate (1.35), phytate (62.79), and tannins (0.72). The results suggested that the ant may be a good source of nutrition.
