Driver ants. Driver ants, from the genus Dorylus, are found in the Old World, especially West Africa and the Congo Basin. Unlike the army ants of the New World, Old World army ants have a functional sting but rarely use it, preferring their razor-sharp, falcate mandibles for defense instead. Dorylus spp. colonies also reach larger sizes than ...
In the case of fire ants, the venom consists mainly of alkaloid (>95%) and protein (<1%) components. [2] Stinging ants cause a cutaneous condition that is different from that caused by biting venomous ants. Particularly painful are stings from fire ants, although the bullet ant's sting is considered by some to be the most painful insect sting.
Pustule formation can only be prevented if the ants are removed before they have a chance to sting. Once venom has been injected, pustules will form and no form of treatment will prevent them from occurring. Medications such as antibiotics, diphenylhydrazines, epinephrines or topical steroids will not affect pustular reactions. [45] [49] [50]
Members of this group have enormous gasters and can regurgitate their stored food when needed. In this way, the colony has a cushion against food shortages. [21] Pharaoh ants have a sophisticated strategy for food preference. They implement two related behaviors. The first is known as satiation.
Dorylus, also known as driver ants, safari ants, or siafu, is a large genus of army ants found primarily in central and east Africa, ...
The red imported fire ant is a member of the S. saevissima species-group. Members can be distinguished by their two-jointed clubs at the end of the funiculus in workers and queens, and the second and third segments of the funiculus are twice as long and broad in larger workers.
The jack jumper ant (Myrmecia pilosula), also known as the jack jumper, jumping jack, hopper ant, or jumper ant, is a species of venomous ant native to Australia.Most frequently found in Tasmania and southeast mainland Australia, it is a member of the genus Myrmecia, subfamily Myrmeciinae, and was formally described and named by British entomologist Frederick Smith in 1858.
Myrmicinae is a subfamily of ants, with about 140 extant genera; [1] their distribution is cosmopolitan. The pupae lack cocoons. Some species retain a functional sting. The petioles of Myrmicinae consist of two nodes. The nests are permanent and in soil, rotting wood, under stones, or in trees. [2]
