Shoot Borer
''Sesamia grisescens'', the pink sugarcane borer, pink stalk borer, shoot borer, sugarcane borer or ramu shoot borer, is a moth of the family Noctuidae. The species was first described by Warren in 1911. It is found in Papua New Guinea, Seram, the Moluccas and New Britain. The larvae are a pest on '' Saccharum officinarum'', although they also feed on other plants, including ''Saccharum robustum'', ''Saccharum spontaneum'', '' Saccharum edule'', ''Pennisetum purpureum'' and '' Panicum maximum''.

Moth
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995.

Saccharum Robustum
''Saccharum robustum'', the robust cane, is a species of plant found in New Guinea. Ecology ''Eumetopina flavipes'', the island sugarcane planthopper, a species of planthopper present throughout South East Asia and is a vector for the Ramu stunt disease, a plant disease which affects sugarcane, occurs also on ''S. robustum''. The pink sugarcane borer (''Sesamia grisescens''), a moth of the family Noctuidae found in Papua New Guinea, Seram, the Moluccas and New Britain, also feeds on ''S. robustum''. '' Scirpophaga excerptalis'', the white top borer or the sugarcane top borer, a moth in the family Crambidae, also feeds on ''S. robustum''.

Leaf Miner
A leaf miner is any one of numerous species of insects in which the larval stage lives in, and eats, the leaf tissue of plants. The vast majority of leaf-mining insects are moths (Lepidoptera), sawflies (Symphyta, the mother clade of wasps), and flies (Diptera). Some beetles also exhibit this behavior. Like woodboring beetles, leaf miners are protected from many predators and plant defenses by feeding within the tissues of the leaves, selectively eating only the layers that have the least amount of cellulose. When attacking ''Quercus robur'' (English oak), they also selectively feed on tissues containing lower levels of tannin, a deterrent chemical produced in great abundance by the tree. The pattern of the feeding tunnel and the layer of the leaf being mined is often diagnostic of the insect responsible, sometimes even to species level. The mine often contains frass, or droppings, and the pattern of frass deposition, mine shape, and host plant identity are useful to determi ...

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 ...

Panicum Maximum
''Megathyrsus maximus'', known as Guinea grass and green panic grass, is a large perennial bunch grass that is native to Africa and Yemen. It has been introduced in the tropics around the world. It has previously been called ''Urochloa maxima'' and ''Panicum maximum''. It was moved to the genus '' Megathyrsus'' in 2003.''Megathyrsus''. Grass Manual. Flora of North America.

Pennisetum Purpureum
''Cenchrus purpureus'', synonym ''Pennisetum purpureum'', also known as Napier grass, elephant grass or Uganda grass, is a species of perennial tropical grass native to the African grasslands. arrell, G., Simons, S.

Saccharum Edule
''Saccharum edule'' is a species of sugarcane, that is a grass in the genus ''Saccharum'' with a fibrous stalk that is rich in sugar. It is cultivated in tropical climates in southeastern Asia. It has many common names which include duruka, tebu telor, Fiji asparagus, dule (Fiji), pitpit (Melanesia) and naviso. The young, unopened flower heads of ''Saccharum edule'' is eaten raw, steamed, or toasted, and prepared in various ways in Southeastern Asia, including Fiji and certain island communities of Indonesia. Description ''Saccharum edule'' is a perennial plant that grows in vigorous clumps that grow to a height of . Although the plant resembles sugarcane from a distance, the stem is much narrower and the leaves thinner and more flexible. The large flower panicles do not open but remain inside their leaf sheaths forming a dense mass. ''Saccharum edule'' is part of the ''Saccharum officinarum'' species complex and its genome has been investigated. Distribution ''Saccharum edu ...

Saccharum Spontaneum
''Saccharum spontaneum'' (wild sugarcane, Kans grass) is a grass native to the Indian Subcontinent. It is a perennial grass, growing up to three meters in height, with spreading rhizomatous roots. In the Terai-Duar savanna and grasslands, a lowland ecoregion at the base of the Himalaya range in Nepal, India, Bangladesh and Bhutan, kans grass quickly colonises exposed silt plains created each year by the retreating monsoon floods, forming almost pure stands on the lowest portions of the floodplain. Kans grasslands are an important habitat for the Indian rhinoceros (''Rhinoceros unicornis''). In Nepal, kans grass is harvested to thatch roofs or fence vegetable gardens. Elsewhere, its ability to quickly colonize disturbed soil has allowed it to become an invasive species that takes over croplands and pasturelands, as has been documented in the Republic of Panama. Uses ''Saccharum spontaneum'' has a considerable number of regional names in the Indian Subcontinent, for instance '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saccharum Officinarum
''Saccharum officinarum'' is a large, strong-growing species of grass in the genus ''Saccharum''. Its stout stalks are rich in sucrose, a simple sugar which accumulates in the stalk internodes. It originated in New Guinea, and is now cultivated in tropical and subtropical countries worldwide for the production of sugar, ethanol and other products. ''Saccharum officinarum'' is one of the most productive and most intensively cultivated kinds of sugarcane. It can interbreed with other sugarcane species, such as ''Saccharum sinense'' and ''Saccharum barberi''. The major commercial cultivars are complex hybrids. About 70% of the sugar produced worldwide comes from ''S. officinarum'' and hybrids using this species. Description ''Saccharum officinarum'', a perennial plant, grows in clumps consisting of a number of strong unbranched stems. A network of rhizomes forms under the soil which sends up secondary shoots near the parent plant. The stems vary in colour, being green, pinki ...

Noctuidae
The Noctuidae, commonly known as owlet moths, cutworms or armyworms, are a family of moths. They are considered the most controversial family in the superfamily Noctuoidea because many of the clades are constantly changing, along with the other families of the Noctuoidea. It was considered the largest family in Lepidoptera for a long time, but after regrouping Lymantriinae, Catocalinae and Calpinae within the family Erebidae, the latter holds this title now. Currently, Noctuidae is the second largest family in Noctuoidea, with about 1,089 genera and 11,772 species. This classification is still contingent, as more changes continue to appear between Noctuidae and Erebidae. Description Adult: Most noctuid adults have drab wings, but some subfamilies, such as Acronictinae and Agaristinae, are very colorful, especially those from tropical regions (e.g. '' Baorisa hieroglyphica''). They are characterized by a structure in the metathorax called the nodular sclerite or epaulette, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
