Spodoptera Mauritia
''Spodoptera mauritia'', the lawn armyworm or paddy swarming caterpillar, is a moth of the family Noctuidae. The species was first described by Jean Baptiste Boisduval in 1833. Able to eat many types of food, it is a major pest throughout the world. Distribution It is widespread from the Red Sea to India, Myanmar, Sri Lanka, Malaya to Australia and widespread in the Pacific Islands, including the Solomons, New Hebrides, Fiji, Samoa, Hawaii, the Society Islands, Austral Islands, Marquesas and the Marshall Islands. Description The wingspan is about 40 mm. It is dark grey brown with a rusty tinge on its body. The abdomen is fuscous. Forewings with sub-basal, antemedial and postmedial double waved lines indistinct. The orbicular small and ochreous, whereas reniform blackish. Submarginal line whitish and irregularly waved. There is a white patch often can be seen between orbicular and reniform and a dark patch on the central marginal area. Hindwings opalescent and semi- hy ...

Jean Baptiste Boisduval
Jean Baptiste Alphonse Déchauffour de Boisduval (24 June 1799 – 30 December 1879) was a French lepidopterist, botanist, and physician. He was one of the most celebrated lepidopterists of France, and was the co-founder of the Société entomologique de France. While best known abroad for his work in entomology, he started his career in botany, collecting a great number of French plant specimens and writing broadly on the topic throughout his career, including the textbook ''Flores française'' in 1828. Early in his career, he was interested in Coleoptera and allied himself with both Jean Théodore Lacordaire and Pierre André Latreille. He was the curator of the Pierre Françoise Marie Auguste Dejean collection in Paris and described many species of beetles, as well as butterflies and moths, resulting from the voyages of the ''Astrolabe'', the expedition ship of Jean-François de Galaup, comte de La Pérouse and the '' Coquille'', that of Louis Isidore Duperrey. He left Paris ...

Marshall Islands
The Marshall Islands ( mh, Ṃajeḷ), officially the Republic of the Marshall Islands ( mh, Aolepān Aorōkin Ṃajeḷ),'' () is an independent island country and microstate near the Equator in the Pacific Ocean, slightly west of the International Date Line. Geographically, the country is part of the larger island group of Micronesia. The country's population of 58,413 people (at the 2018 World Bank Census) is spread out over five islands and 29 coral atolls, comprising 1,156 individual islands and islets. The capital and largest city is Majuro. It has the largest portion of its territory composed of water of any sovereign state, at 97.87%. The islands share maritime boundaries with Wake Island to the north, Kiribati to the southeast, Nauru to the south, and Federated States of Micronesia to the west. About 52.3% of Marshall Islanders (27,797 at the 2011 Census) live on Majuro. In 2016, 73.3% of the population were defined as being "urban". The UN also indicates a population d ...

Bolas Spider
A bolas spider is a member of the orb-weaver spider (family Araneidae) that, instead of spinning a typical orb web, hunts by using one or more sticky "capture blobs" on the end of a silk line, known as a "bolas". By swinging the bolas at flying male moths or moth flies nearby, the spider may snag its prey rather like a fisherman snagging a fish on a hook. Because of this, they are also called angling or fishing spiders (although the remotely related genus ''Dolomedes'' is also called a fishing spider). The prey is lured to the spider by the production of up to three sex pheromone-analogues. Bolas spiders have been treated as either the whole or part of either the tribe "Mastophoreae" or Mastophorini, the subfamily Mastophorinae, or the informal group mastophorines. Recent studies show that the genus ''Celaenia'', which does not use a bolas, belongs in the same taxonomic group. Description Bolas spiders are small nocturnal animals with conspicuous outgrowths on the upper (dorsa ...

Feces
Feces ( or faeces), known colloquially and in slang as poo and poop, are the solid or semi-solid remains of food that was not digested in the small intestine, and has been broken down by bacteria in the large intestine. Feces contain a relatively small amount of metabolic waste products such as bacterially altered bilirubin, and dead epithelial cells from the lining of the gut. Feces are discharged through the anus or cloaca during defecation. Feces can be used as fertilizer or soil conditioner in agriculture. They can also be burned as fuel or dried and used for construction. Some medicinal uses have been found. In the case of human feces, fecal transplants or fecal bacteriotherapy are in use. Urine and feces together are called excreta. Skatole is the principal compound responsible for the unpleasant smell of feces. Characteristics The distinctive odor of feces is due to skatole, and thiols (sulfur-containing compounds), as well as amines and carboxylic acids. Skatole ...

Urea
Urea, also known as carbamide, is an organic compound with chemical formula . This amide has two amino groups (–) joined by a carbonyl functional group (–C(=O)–). It is thus the simplest amide of carbamic acid. Urea serves an important role in the metabolism of nitrogen-containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals. It is a colorless, odorless solid, highly soluble in water, and practically non-toxic ( is 15 g/kg for rats). Dissolved in water, it is neither acidic nor alkaline. The body uses it in many processes, most notably nitrogen excretion. The liver forms it by combining two ammonia molecules () with a carbon dioxide () molecule in the urea cycle. Urea is widely used in fertilizers as a source of nitrogen (N) and is an important raw material for the chemical industry. In 1828 Friedrich Wöhler discovered that urea can be produced from inorganic starting materials, which was an important conceptual milestone ...

Uric Acid
Uric acid is a heterocyclic compound of carbon, nitrogen, oxygen, and hydrogen with the formula C5H4N4O3. It forms ions and salts known as urates and acid urates, such as ammonium acid urate. Uric acid is a product of the metabolic breakdown of purine nucleotides, and it is a normal component of urine. High blood concentrations of uric acid can lead to gout and are associated with other medical conditions, including diabetes and the formation of ammonium acid urate kidney stones. Chemistry Uric acid was first isolated from kidney stones in 1776 by Swedish chemist Carl Wilhelm Scheele. In 1882, the Ukrainian chemist Ivan Horbaczewski first synthesized uric acid by melting urea with glycine. Uric acid displays lactam–lactim tautomerism (also often described as keto–enol tautomerism). Although the lactim form is expected to possess some degree of aromaticity, uric acid crystallizes in the lactam form, with computational chemistry also indicating that tautomer to be the most s ...

Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal forms o ...

Casuarina Equisetifolia
''Casuarina equisetifolia'', common names ''Coastal She-oak'' or ''Horsetail She-oak'' (sometimes referred to as the Australian pine tree or whistling pine tree outside Australia), is a she-oak species of the genus ''Casuarina''. The native range extends throughout Southeast Asia, Northern Australia and the Pacific Islands; including Thailand, Myanmar, Vietnam, Malaysia, Singapore, Brunei, Indonesia, East Timor, and the Philippines (where it is known as agoho pine), east to Papua New Guinea, French Polynesia, New Caledonia, and Vanuatu, and south to Australia (north of Northern Territory, north and east Queensland, and north-eastern New South Wales). Populations are also found in Madagascar, but it is doubtful if this is within the native range of the species. The species has been introduced to the Southern United States and West Africa. It is an invasive species in Florida, South Africa, India and Brazil. Taxonomy ''Casuarina equisetifolia'' was officially described by Lin ...

Oryza Sativa
''Oryza sativa'', commonly known as Asian rice or indica rice, is the plant species most commonly referred to in English as ''rice''. It is the type of farmed rice whose cultivars are most common globally, and was first domesticated in the Yangtze River basin in China 13,500 to 8,200 years ago. ''Oryza sativa'' belongs to the genus '' Oryza'' of the grass family Poaceae. With a genome consisting of 430 Mbp across 12 chromosomes, it is renowned for being easy to genetically modify and is a model organism for the botany of cereals. Classification ''Oryza sativa'' contains two major subspecies: the sticky, short-grained ''japonica'' or ''sinica'' variety, and the nonsticky, long-grained ' rice variety. ''Japonica'' was domesticated in the Yangtze Valley 9–6,000 years ago, and its varieties can be cultivated in dry fields (it is cultivated mainly submerged in Japan), in temperate East Asia, upland areas of Southeast Asia, and high elevations in South Asia, while ''indica'' w ...

Sorghum Bicolor
''Sorghum bicolor'', commonly called sorghum () and also known as great millet, broomcorn, guinea corn, durra, imphee, jowar, or milo, is a Poaceae, grass species cultivated for its grain, which is used for food for humans, animal feed, and ethanol production. Sorghum originated in Africa, and is now cultivated widely in tropical and subtropical regions. Sorghum is the world's fifth-most important cereal crop after rice, wheat, maize, and barley, with 59.34 million metric tons of annual global production in 2018. ''S. bicolor'' is typically an annual, but some cultivars are perennial. It grows in clumps that may reach over 4 m high. The grain is small, ranging from 2 to 4 mm in diameter. Sweet sorghums are sorghum cultivars that are primarily grown for forage, syrup production, and ethanol; they are taller than those grown for grain. ''Sorghum bicolor'' is the cultivated species of sorghum; its wild relatives make up the botanical genus ''Sorghum''. History The first archae ...

Pennisetum Clandestinum
The tropical grass species ''Cenchrus clandestinus'' (previously Pennisetum clandestinum) is known by several common names, most often kikuyu grass, as it is native to the highland regions of East Africa that is home to the Kikuyu people. Because of its rapid growth and aggressive nature, it is categorised as a noxious weed in some regions. However, it is also a popular garden lawn species in Australia, New Zealand, South Africa and the southern region of California in the United States, as it is inexpensive and moderately drought-tolerant. In addition, it is useful as pasture for livestock grazing and serves as a food source for many avian species, including the long-tailed widowbird. The flowering culms are very short and "hidden" amongst the leaves, giving this species its specific epithet (''clandestinus''). Description and habitat ''Cenchrus clandestinus'' is a rhizomatous grass with matted roots and a grass-like or herbaceous habit. The leaves are green, flattened or ...
