Termites are found on all continents except Antarctica. The diversity of termite species is reduced in North America and Europe (10 species known in Europe and 50 in North America), but is high in South America, where over 400 species are known.34 Of the 3,000 termite species currently categorized, 1,000 are found in Africa, where mounds are really abundant in certain regions.
As a result of their soft cuticles, termites do not inhabit cold or cool habitats.36 There are three ecological groups of termites: dampwood, drywood and subterranean. Dampwood termites are found only in coniferous forests, and drywood termites are found in hardwood forests; subterranean termites live in widely diverse areas.34 One species in the drywood category is that the West Indian drywood termite (Cryptotermes brevis), which can be an invasive species in Australia.37.
Some Ideas on Termite Control For Soil You Need To
Termites are generally modest, measuring between 4 to 15 millimetres (0.16 to 0.59Â in) in length.34 The biggest of all extant termites are the queens of those species Macrotermes bellicosus, measuring around over 10 centimetres (4Â in) in length.38 Another giant termite, the extinct Gyatermes styriensis, flourished in Austria during the Miocene and had a wingspan of 76 millimetres (3.0Â in) and a body length of 25 millimetres (0.98Â in).39note 1.
Most worker and soldier termites are completely blind as they do not have a pair of eyes. But some species, like Hodotermes mossambicus, have compound eyes that they utilize for orientation and also to distinguish sunlight from moonlight.40 The alates (winged males and females) have eyes along with lateral ocelli.
Termite antennae have a number of functions such as the sensing of taste, touch, odours (including pheromones), heat and vibration. The three basic segments of a termite antenna include a scape, a pedicel (usually shorter than the scape), and the flagellum (all segments beyond the scape and pedicel). The mouth parts contain https://innovativepestcontroladelaide.com.au/pest-inspection-adelaide/ a maxillae, a labium, and a pair of mandibles.
Consistent with all insects, the anatomy of the termite thorax consists of 3 segments: the prothorax, the mesothorax and the metathorax. Each segment contains a pair of legs. On alates, the wings are at the mesothorax and metathorax. Even the mesothorax and metathorax have well-developed exoskeletal plates; the prothorax has smaller plates. .
The Buzz on Termite Control For Trees
Termites have a ten-segmented abdomen with 2 plates, the tergites and the sternites. The tenth abdominal segment has a pair of short cerci.45 There are ten tergites, of which nine are broad and one is elongated. The reproductive organs are similar to those in cockroaches but are more simplified. By way of instance, the intromittent organ is not present in penile alates, and the sperm is either immotile or aflagellate.
The non-reproductive castes of thieves are wingless and rely solely on their six legs for locomotion. The alates fly only to get a short amount of time, so that they also rely on their own legs. The appearance of the legs is similar in each and every caste, but the soldiers have larger and thicker legs.

The number of tibial spurs on an individual's leg varies. Some species of a knockout post termite have an arolium, found between the claws, which can be present in species which scale on smooth surfaces but is absent in many termites.49.
Unlike in ants, the hind-wings and fore-wings are of equivalent length.2 the majority of the time, the alates are poor flyers; their technique is to launch themselves in the atmosphere and fly in a random direction. Studies show that in comparison to bigger termites, smaller termites cannot fly long distances. When a termite is in flight, its wings remain in a ideal angle, and when the termite is at rest, its wings remain parallel to your own body.51.
Worker termites undertake the maximum labour within the colony, being responsible for foraging, food storage, and brood and nest maintenance.53 Workers are tasked with the digestion of cellulose in meals and are thus the most likely caste to be found in infested timber. The process of worker termites feeding different nestmates is popularly known as trophallaxis.
The 15-Second Trick For Termite Control For Soil
Some termite species do not have a true worker caste, instead relying on nymphs that do the exact same job without differentiating as a distinct caste.53.
