Kerria Lacca
''Kerria lacca'' is a species of insect in the family Kerriidae, the lac insects. These are in the superfamily Coccoidea, the scale insects. 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 products.Raman, A. (2014)Discovery of ''Kerria lacca'' (Insecta: Hemiptera: Coccoidea), the lac insect, in India in the late 18th century.''Current Science'' 106(6), 886. This insect is native to Asia.Ahmad, A., et al. (2012)Mouthparts and stylet penetration of the lac insect ''Kerria lacca'' (Kerr) (Hemiptera: Tachardiidae).''Arthropod Structure & Development'' 41, 435-441. Biology ''Kerria lacca'' produces a dye and a wax as natural secretions. The life cycle of this scale insect proceeds with the first instar of the larval stages, which are known as "crawlers". Larvae in this stage crawl along the branches of their host plants and feed on the phloem. As they pierce the branches to reach the phl ...

Harold Maxwell-Lefroy
Harold Maxwell-Lefroy (20 January 1877 – 14 October 1925) was an English entomologist. He served as a Professor of Entomology at Imperial College London and as the second Imperial Entomologist to India. He left India after the death of two of his children from insect-borne diseases. He worked on applied entomology and initiated experiments on the use of chemicals to control insects. A formula he developed was utilized to save Westminster Hall from destruction by wood-boring beetles, while others were used to control lice in the trenches during the First World War. The success of his chemicals led to increased demand and the founding of Rentokil, a company for insecticide production. He was killed in an accident while experimenting on fumigants to control insects. Biography Maxwell-Lefroy was born in the village of Crondall, Hampshire, to Charles James Maxwell Lefroy of the 14th Hussars (whose grandfather was James Walker who had designed the Regent or Vauxhall Bridge in 1816) ...

Schleichera Oleosa
''Schleichera'' is a monotypic genus of plants in the soapberry family, Sapindaceae. There is only one species, ''Schleichera oleosa'', a tree that occurs in the Indian Subcontinent and Southeast Asia. Species ''Schleichera oleosa'', kusum tree, Ceylon oak, lac tree, gum lac tree. It is a large deciduous (nearly evergreen) tree with a comparatively short fluted trunk and a shade spreading crown. It is frost and drought hardy and is subject to damage by grazing. It produces root-suckers freely, and it has good cropping power. The wood is very hard and reddish brown. This tree is noted for its growth of new leaves that are bright red. In India the growth of these bright red leaves happens around March. The leaves are pinnate, with each leaf having 2-4 leaflets. The tree is host to Kusumi Lac (Kerria lacca), a lac insect which is native to India. Its seeds are the source of Kusum oil. Flowers: The flowers are tiny and hardly noticeable, occurring in short dense yellow clusters. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Hemolymph
Hemolymph, or haemolymph, is a fluid, analogous to the blood in vertebrates, that circulates in the interior of the arthropod (invertebrate) body, remaining in direct contact with the animal's tissues. It is composed of a fluid plasma in which hemolymph cells called hemocytes are suspended. In addition to hemocytes, the plasma also contains many chemicals. It is the major tissue type of the open circulatory system characteristic of arthropods (e.g. arachnids, crustaceans and insects). In addition, some non-arthropods such as molluscs possess a hemolymphatic circulatory system. Oxygen-transport systems were long thought unnecessary in insects, but ancestral and functional hemocyanin has been found in the hemolymph. Insect "blood" generally does not carry hemoglobin, although hemoglobin may be present in the tracheal system instead and play some role in respiration. Method of transport In the grasshopper, the closed portion of the system consists of tubular hearts and an aort ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Han dynasty annexed Northern and Central Vietnam under Chinese rule from 111 BC, until the first dynasty emerged in 939. Successive monarchical dynasties absorbed Chinese influences through Confucianism and Buddhism, and expanded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parasitoid Wasp
Parasitoid wasps are a large group of hymenopteran superfamilies, with all but the wood wasps (Orussoidea) being in the wasp-waisted Apocrita. As parasitoids, they lay their eggs on or in the bodies of other arthropods, sooner or later causing the death of these hosts. Different species specialise in hosts from different insect orders, most often Lepidoptera, though some select beetles, flies, or bugs; the spider wasps (Pompilidae) exclusively attack spiders. Parasitoid wasp species differ in which host life-stage they attack: eggs, larvae, pupae, or adults. They mainly follow one of two major strategies within parasitism: either they are endoparasitic, developing inside the host, and koinobiont, allowing the host to continue to feed, develop, and moult; or they are ectoparasitic, developing outside the host, and idiobiont, paralysing the host immediately. Some endoparasitic wasps of the superfamily Ichneumonoidea have a mutualistic relationship with polydnaviruses, the vir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
