| ants | Insects of the family formicidae, very common and widespread, probably the most successful of all the insect groups. All ants are social insects, and most colonies contain three castes, queens, males, and workers. Their habits are often very elaborate and a great many studies have been made of ant behaviour. Ants produce a number of secretions that function in offense, defense, and communication. (12 Dec 1998) |

| ants, fire | Originally from S. America. Among the worst insect pests ever to invade the U.S. Red or yellowish ants of small-to-medium size with a severe sting that burns like fire. They normally feed on small insects but, with denser populations, they eat seeds and seedling plants, damage grain and vegetable crops, invade kitchens, attack newly hatched poultry and the young of ground-nesting wild birds. Fire ants can kill newborn domestic and wild animals. Each colony is composed of a queen, winged males and females and 3 kinds of workers. A nest averages about 25,000 workers, but far larger populations are common. Semipermanent nests are large mounds of excavated soil with openings for ventilation. Since nests may number 50-100 (or more) in a heavily infested field, cultivating becomes difficult (or impossible). Fire ants belong to the genus Solenopsis. Also called thief ants, a scourge, these red or yellow ants of small-to-medium size, originally from South America, have a severe sting that burns like fire and can trigger an allergic reaction. Avoidance and prompt treatment are essential. (12 Dec 1998) |
| ants, velvet | Common in most parts of the world including the Southern and Southwestern U.S., velvet ants are not true ants but rather parasitic wasps. Their sting can trigger allergic reactions. Avoidance, prompt treatment and, in selected cases, allergy injection therapy are useful. (12 Dec 1998) |
