General Overview
Ants are among the most successful of all insects. There are about seven different species which are of the most concern to southeast Georgia: Carpenter Ants, Fire Ants, Pharaoh Ants, Acrobat Ants, Argentine Ants, Crazy Ants, and Odorous House Ants. Like termites, they are social insects and live in colonies. Ant colonies include a collection of workers, one or more reproductives, eggs, larvae, and pupae, and adults. Many species prefer to nest in the ground; others will be found in wood, such as dead logs, fence posts, hollow trees, or even wood within structures. Unlike termites, ants do not eat wood, they merely hollow out portions of it known as galleries. Many adult male and female species are winged, as are adult termites. Most structure infesting species either do not have the ability to sting or retain it only to a limited degree. However, many tropical ants from the tropical regions, some of which have been introduced into the United States, are particularly serious pests because of their ability to sting. This sting involves piercing the skin with the ovipositor, a structure located in the tip of the abdomen of females. Venom secreted by a gland associated with the ovipositor not only creates rapid, intense pain but also may cause serious, even life threatening, allergic reactions in some people.
Life Cycle
Ants have a complete metamorphosis comprised of
four stages: egg, larvae, pupa, and adult. Eggs are almost
microscopic in size. After the eggs hatch, the larval stage
emerges. Soon after, most species will become encased
in a silk cocoon which is then known as the pupal stage.
Often times when a nest is disturbed, the adults are seen
moving these pupae which many people mistake for eggs.
The worker caste is comprised of strictly females which
feed and care for the eggs, larvae, pupae, and the queen.
Feeding Habits
Some ant species feed on a wide variety of food items, while others typically feed on a rather narrow range of foods. Food preferences may also change significantly during the course of a season, especially for outdoor species, or depending on the specific needs of the colony. Periods of high egg production typically require foraging ants to bring back proteins to the queen or queens, while at other times foragers may prefer to gather sugars or greases for their own energy needs or to promote larval growth. Foraging ants bring food or water back to the colony and pass it to other nest-tending workers by a mouth-to-mouth process called trophalaxis. Nest-tending workers then pass the food to larvae or the queens. Workers may stimulate the larvae to regurgitate liquid food for use within the colony.
