Fascination About Termite Control For Plants
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 extremely abundant in certain regions.
As a result of their soft cuticles, termites do not inhabit cool or cold habitats.36 There are three environmental 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 regions.34 One species in the drywood group is that the West Indian drywood termite (Cryptotermes brevis), which can be an invasive species in Australia.37.
Facts About Termite Control For Plants Revealed
Termites are usually 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 the species Macrotermes bellicosus, measuring around over 10 centimetres (4Â in) in length.38 Another giant termite, the extinct Gyatermes styriensis, thrived 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 blind as they do not have a pair of eyes. But some species, such as Hodotermes mossambicus, have compound eyes that they use for orientation and 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 touch, taste, odours (including pheromones), heat and vibration. The three basic segments of a termite antenna include a scape, a pedicel (typically shorter than the scape), and the flagellum (all segments beyond the scape and pedicel). The mouth parts contain a maxillae, a labium, and a set of mandibles.
Consistent with insects, the anatomy of the termite thorax consists of three segments: the prothorax, the mesothorax and the metathorax. Each segment contains a set of legs. On alates, the wings are at the mesothorax and metathorax. The mesothorax and metathorax have well-developed exoskeletal plates; the prothorax has smaller plates. .
An Unbiased View of Termite Control For Soil
Termites have click over here now a ten-segmented abdomen using 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 wide and one is elongated. The reproductive organs are similar to those in cockroaches but are more simplified. For example, the intromittent organ is not present in penile alates, and the semen 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 for a short amount of time, so they also rely on their own legs. The appearance of the legs is comparable in each caste, but the soldiers have larger and thicker legs.

The number of tibial spurs on an individual's leg fluctuates. Some species of termite have an arolium, located between the claws, which can be present in species that climb on smooth surfaces but is absent in many termites.49.
Unlike in ants, the hind-wings and fore-wings are of equal length.2 the majority of the time, the alates are poor stocks; their technique is to launch themselves in the air and fly in a random direction. Studies show that click here for more in comparison to larger termites, smaller vases cannot fly long distances. When a termite is in flight, its wings remain in a right angle, and when the termite is at rest, its wings remain parallel to your own body.51.
Worker termites undertake the most labor 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 imp source found in infested timber. The procedure for worker termites feeding other nestmates is popularly known as trophallaxis.
Not known Factual Statements About Termite Control For Plants
Some termite species do not own a true worker caste, instead relying on nymphs that perform the exact same job without differentiating as a separate caste.53.
