[25] The oldest termite nest discovered is believed to be from the Upper Cretaceous in West Texas, where the oldest known faecal pellets were also discovered. [215], The damage caused by termites costs the southwestern United States approximately $1.5 billion each year in wood structure damage, but the true cost of damage worldwide cannot be determined. Termites are a delicacy in the diet of some human cultures and are used in many traditional medicines. In the eusocial Hymenoptera, the workers are exclusively female. A termite native to the United States, Reticulitermes flavipes, was found in the hothouses of the Royal Palace in Schönbrunn, in Vienna, and the species was reported and described in that location before it was discovered in the United States. [202], Nests are considered mounds if they protrude from the earth's surface. Fumigation is the most effective method for eliminating a dry-wood termite infestation. Which beetle is also known as the tumblebug and can eat its weight in 24 hours? [79] The number of termites in a colony also varies, with the larger species typically having 100–1,000 individuals. [239], African tribes in several countries have termites as totems, and for this reason tribe members are forbidden to eat the reproductive alates. Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are the sister group to wood eating cockroaches of the genus Cryptocercus. Termites are major detritivores, particularly in the subtropical and tropical regions, and their recycling of wood and plant matter is of considerable ecological importance. Termites are infected by viruses including Entomopoxvirinae and the Nuclear Polyhedrosis Virus. Mastotermitidae Termites are consumed in many regions globally, but this practice has only become popular in developed nations in recent years. [46] When termites go out to look for food, they forage in columns along the ground through vegetation. Thermite is a pyrotechnic composition of metal powder and metal oxide. [78] After mating, the pair never go outside and spend the rest of their lives in the nest. A trail can be identified by the faecal deposits or runways that are covered by objects. [39] Of the 3,000 termite species currently classified, 1,000 are found in Africa, where mounds are extremely abundant in certain regions. [9], Termites were formerly placed in the order Isoptera. Drywood Termites Facts, Identification & Control Latin Name. Approximately 1.1 million active termite mounds can be found in the northern Kruger National Park alone. [211] Their habit of remaining concealed often results in their presence being undetected until the timbers are severely damaged, with only a thin exterior layer of wood remaining, which protects them from the environment. termite holes. Construction and design practices that can prevent the initial entry of subterranean termites into a structure include the use of pressure-treated wood, treated concrete foundation blocks, and reinforced concrete foundations that extend at least 15.2 cm (6 inches) above the ground and have no cracks or contact with any outside wood. There are two types of termites commonly encountered by homeowners: the worker and the swarmer. [73] Nymphs first moult into workers, and then some workers go through further moulting and become soldiers or alates; workers become alates only by moulting into alate nymphs.

However, some species, such as Hodotermes mossambicus, have compound eyes which they use for orientation and to distinguish sunlight from moonlight. Fuels include aluminium, magnesium, titanium, zinc, silicon, and boron. [52] The genitals in females are also simplified. [159][160] Each colony has its own distinct odour. [118] The termite genera Apicotermes and Trinervitermes are known to have polycalic species. Some ants live within damp/decaying wood, but do not actually eat the wood. Dry-wood termites nest in the wood on which they feed and do not invade a structure from the soil. Termites are found on all continents except Antarctica. A termite nest can be considered as being composed of two parts, the inanimate and the animate. Termites recycle wood products into the soil by feeding on cellulose—the main cell wall component of plants—and breaking it down. Serritermitidae This material is made from feces. Several hundred species are economically significant as pests that can cause serious damage to buildings, crops, or plantation forests. [181] Certain species of ants in the subfamily Ponerinae conduct these raids although other ant species go in alone to steal the eggs or nymphs. [193] A total of 26 species of termites were present in the three sites, and 196 encounters were recorded in the transects. [37][34], External phylogeny These Nasutitermes nests are mainly composed of partially biodegraded wood material from the stems and branches of mangrove trees, namely, Rhizophora mangle (red mangrove), Avicennia germinans (black mangrove) and Laguncularia racemose (white mangrove). [200], Arboreal carton nests of mangrove swamp-dwelling Nasutitermes are enriched in lignin and depleted in cellulose and xylans. The result is a self-organised process whereby the information that directs termite activity results from changes in the environment rather than from direct contact among individuals. [212] Of the 3,106 species known, only 183 species cause damage; 83 species cause significant damage to wooden structures. [46][145] These methods of communication are used in a variety of activities, including foraging, locating reproductives, construction of nests, recognition of nestmates, nuptial flight, locating and fighting enemies, and defending the nests. Ants: ants are scavengers, with different species foraging for different foods. This struggle among the queens leads to the elimination of all but a single queen, which, with the king, takes over the colony. [217] The goal of termite control is to keep structures and susceptible ornamental plants free from termites. Termites and ants can re-colonise untilled land that contains crop stubble, which colonies use for nourishment when they establish their nests. [230], The termite gut has inspired various research efforts aimed at replacing fossil fuels with cleaner, renewable energy sources. Introduced species, because they are not so well equipped as native species to adapt to changes in their new environments, tend to seek shelter in protected, man-made environments such as buildings and thus are likely to become the most serious pests, causing significant damage to houses and wooden furnishings. Termite Facts for Kids. Termite workers, by comparison, are transparent, light or creamy white in color, and they avoid light. [145][158], When termites construct their nests, they use predominantly indirect communication. Fipronil. These swarms attract a wide variety of predators. Coeditor of. [26] Claims that termites emerged earlier have faced controversy. [59] It frees the parents from feeding all but the first generation of offspring, allowing for the group to grow much larger and ensuring that the necessary gut symbionts are transferred from one generation to another. In the second phase, workers appear in large numbers at the site. These shelter tubes can be found on walls and other structures. [48], Termites have a ten-segmented abdomen with two plates, the tergites and the sternites. [241] Abandoned mounds are viewed as structures created by spirits, believing a local guardian dwells within the mound; this is known as Keramat and Datok Kong. Phylogenetic studies have shown that the closest relative to the termite is the cockroach; for this reason termites are sometimes placed in the order Dictyoptera, which also contains the mantids. A Brazilian study investigated the termite assemblages of three sites of Caatinga under different levels of anthropogenic disturbance in the semi-arid region of northeastern Brazil were sampled using 65 x 2 m transects. [145][163], In some species, some soldiers block tunnels to prevent their enemies from entering the nest, and they may deliberately rupture themselves as an act of defence.
