This species is perhaps the most commercially important lac insect, being a main source of lac, a resin which can be refined into shellac and other product
Kerriidae is a family of scale insects, commonly known as lac insects or lac scales.Some members of the genera Metatachardia, Tachardiella, Austrotacharidia, Afrotachardina, Tachardina, and Kerria are raised for commercial purposes, though the most commonly cultivated species is Kerria lacca.
The word lac is derived from the Sanskrit word lākshā '(लाक्षा) representing the number 100 thousand, which was used for both the lac insect (because of their enormous number) and the scarlet resinous secretion it produces that was used as wood finish, lacquerware, skin cosmetic, ornaments and dye for wool and silk in ancient India and neighbouring areas.
Spider mites make webs that protects them against predators. Symphyla produce silk through a pair of spinnerets, which is used for nest building, escape and defense. [7] Pseudoscorpions make silk chambers in which they molt. Goats have been genetically modified to produce milk containing extractable silk proteins. [8] Dulichia rhabdoplastis [9]
[62] [63] In Taiwan, ST59 strains, some of which are resistant to many non-beta-lactam antibiotics, have arisen as common causes of skin and soft tissue infections in the community. In a remote region of Alaska, unlike most of the continental U.S., USA300 was found only rarely in a study of MRSA strains from outbreaks in 1996 and 2000 as well ...
The fly lays eggs on the forelegs of large animals. The eggs hatch within a week and penetrate the skin, where they migrate throughout the connective tissues (H. bovis) or to the esophagus (H. lineatum). After a few months, the larvae travel back to the skin surface and cause swellings called "warbles".
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
Fulgora laternaria can reach a length of 85–90 millimetres (3.3–3.5 in), with a wingspan up to 100–150 millimetres (3.9–5.9 in). This insect has a protuberance at its head as long as 10–15 millimetres (0.39–0.59 in), looking like a peanut and showing false eyes to resemble that of a lizard or a serpent.
