More About Termite Control Pdf
Termites going through incomplete metamorphosis on the road to becoming alates form a subcaste in certain species of termite, functioning as potential supplementary reproductives. These supplementary reproductives only mature into primary reproductives upon the passing of a king or queen, or when the primary reproductives are separated from the colony.6676 Supplementaries have the capacity to replace a deceased principal reproductivesystem, and there may also be more than just a single supplementary within a colony.53 Some queens have the ability to switch from sexual reproduction to asexual reproduction.
The neotropical termite Embiratermes neotenicus and lots of other associated species produce colonies that contain a main king accompanied by a main queen or by up to 200 neotenic queens which had originated through thelytokous parthenogenesis of a founding primary queen.79 The form of parthenogenesis probably employed maintains heterozygosity in the passage of their genome from mom to daughter, thus avoiding inbreeding depression. .
Termites are detritivores, consuming dead plants in any degree of decomposition. They also play a vital role in the ecosystem by recycling waste material such as dead timber, faeces and plants.8182 Many species consume cellulose, having a specialised midgut that divides down the fibre.83 Termites are considered to be a significant source (11%) of atmospheric methane, one of the prime greenhouse gases, generated from the breakdown of cellulose.84 Termites rely primarily upon symbiotic protozoa (metamonads) and other microbes like flagellate protists in their guts to digest the cellulose to them, allowing them to absorb the end products for their own use.8586 Gut protozoa, such as Trichonympha, in turn, rely on symbiotic bacteria embedded on their surfaces to create a number of the necessary intestinal enzymes.

The flagellates have been lost in Termitidae.878889 Scientists' understanding of the relationship between the termite digestive tract and also the microbial endosymbionts remains rudimentary; what is true in most termite species, however, is that the employees feed the different members of the colony with substances derived from the digestion of plant material, either in the mouth or anus.54 Judging from closely related bacterial species, it is strongly presumed the termites' and cockroach's gut microbiota derives from their dictyopteran ancestors.90.
Certain species such as Gnathamitermes tubiformans have seasonal food habits. As an example, they may preferentially consume Red three-awn (Aristida longiseta) during the summer, Buffalograss (Buchloe dactyloides) from May to August, and blue grama Bouteloua gracilis during spring, summer and autumn. Colonies of G. tubiformans consume less food in spring than they perform during autumn when their feeding activity is high.91.
Numerous forests differ in their susceptibility to termite attack; the differences are attributed to these factors as moisture content, hardness, and resin and lignin content. In one study, the drywood termite Cryptotermes brevis strongly preferred poplar and walnut woods to other woods that were generally rejected from the termite colony.
Some varieties of termite practice fungiculture. They maintain a"garden" of specialised fungi of genus Termitomyces, which can be nourished from the excrement of the insects. When the fungi are eaten, their spores pass undamaged through the intestines of their termites to complete the cycle by germinating in the fresh faecal pellets.9394 Molecular evidence suggests that the household Macrotermitinae developed agriculture roughly 31 million decades back.

Originally living in the rainforest, fungus farming allowed them to colonise the African savannah and other new environments, eventually expanding into Asia.95.
Depending on their feeding habits, termites are placed into two groups: the lower termites and higher termites. The lower vases predominately feed on timber. As wood is difficult to digest, termites want to consume fungus-infected timber because it is easier to digest and the fungi are high in protein. Meanwhile, the higher termites consume a vast array of substances, including faeces, humus, grass, leaves and roots.96 The gut in the lower weeds contains many species of bacteria along with protozoa, whereas the greater termites only have a few species of bacteria with no protozoa.97.
