Eumetopina Flavipes
''Eumetopina flavipes'', the island sugarcane planthopper, is a species of planthopper present throughout South East Asia. ''E. flavipes'' is a vector for Ramu stunt disease, a plant disease which affects sugarcane. Ramu stunt disease is widespread throughout Papua New Guinea, but has not been detected in Australia. ''Eumetopina'' is thought to have evolved in Papua New Guinea, where up to four undescribed species have been collected, but many more may be present. In Papua New Guinea, ''E. flavipes'' occurs on ''Saccharum officinarum'', '' S. robustum'', '' S. edule'' and ''Saccharum'' hybrids sugarcane. Virus-free populations of ''E. flavipes'' are present on ''Saccharum'' hybrids and ''S. officinarum'' on many islands in the Torres Strait, and a number of small populations persist on the northern Cape York Peninsula Cape York Peninsula is a large peninsula located in Far North Queensland, Australia. It is the largest unspoiled wilderness in northern Australia.Mittermeier, ...

Insect Vectors Of Plant Pathogens
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Inse ...

Agricultural Pest Insects
A pest is any animal or plant harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops. Some animals are disliked because they bite or sting; snakes, wasps, ants, bed bugs, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food, beetles, which tunnel into the woodwork, and other animals that scuttle about on the floor at night, like cockroaches, which are often associated with unsanitary conditions. Agricultural and horticultural crops are attacked by a wide variety of pests, the most important being insects, mite ...

Hemiptera Of Asia
Hemiptera (; ) is an order (biology), order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, Reduviidae, assassin bugs, Cimex, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking Insect mouthparts, mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as Ant, ants, Bee, bees, Beetle, beetles, or Butterfly, butterflies.

Cape York Peninsula
Cape York Peninsula is a large peninsula located in Far North Queensland, Australia. It is the largest unspoiled wilderness in northern Australia.Mittermeier, R.E. et al. (2002). Wilderness: Earth’s last wild places. Mexico City: Agrupación Sierra Madre, S.C. The land is mostly flat and about half of the area is used for grazing cattle. The relatively undisturbed eucalyptus-wooded savannahs, tropical rainforests and other types of habitat are now recognised and preserved for their global environmental significance. Although much of the peninsula remains pristine, with a diverse repertoire of endemic flora and fauna, some of its wildlife may be threatened by industry and overgrazing as well as introduced species and weeds.Mackey, B. G., Nix, H., & Hitchcock, P. (2001). The natural heritage significance of Cape York Peninsula. Retrieved 15 January 2008, froepa.qld.gov.au. The northernmost point of the peninsula is Cape York (). The land has been occupied by a number of Abor ...

Torres Strait
The Torres Strait (), also known as Zenadh Kes, is a strait between Australia and the Melanesian island of New Guinea. It is wide at its narrowest extent. To the south is Cape York Peninsula, the northernmost extremity of the Australian mainland. To the north is the Western Province of Papua New Guinea. It is named after the Spanish navigator Luís Vaz de Torres, who sailed through the strait in 1606. Prehistory The islands of the Torres Strait have been inhabited by humans for at least 2,500 years and possibly much longer. The various Torres Strait Islander communities have a unique culture and long-standing history with the islands and nearby coastlines. Their maritime-based trade and interactions with the Papuans to the north and the Australian Aboriginal communities have maintained a steady cultural diffusion among the three societal groups, dating back thousands of years. History The first recorded European navigation of the strait was by Luís Vaz de Torres, a pilot ...

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 ...

Sugarcane
Sugarcane or sugar cane is a species of (often hybrid) tall, Perennial plant, perennial grass (in the genus ''Saccharum'', tribe Andropogoneae) that is used for sugar Sugar industry, production. The plants are 2–6 m (6–20 ft) tall with stout, jointed, fibrous stalks that are rich in sucrose, which accumulates in the Plant stem, stalk internodes. Sugarcanes belong to the grass family, Poaceae, an economically important flowering plant family that includes maize, wheat, rice, and sorghum, and many forage crops. It is native to the warm temperate and tropical regions of India, Southeast Asia, and New Guinea. The plant is also grown for biofuel production, especially in Brazil, as the canes can be used directly to produce ethyl alcohol (ethanol). Grown in tropical and subtropical regions, sugarcane is the world's largest crop by production quantity, totaling 1.9 billion tonnes in 2020, with Brazil accounting for 40% of the world total. Sugarcane accounts for 79% of sug ...

Ramu Stunt Disease
The Ramu stunt disease is a disease of the sugarcane widespread throughout Papua New Guinea, but not detected in Australia. ''Eumetopina flavipes'', the island sugarcane planthopper, is a species of planthopper present throughout South East Asia which is a vector for the disease. It was first detected in the 1980s. It is thought to be either of viral origin or associated with a ''Phytoplasma'' bacterium.The Phytoplasma Associated with Ramu Stunt Disease of Sugarcane Is Closely Related to the White Leaf Phytoplasma Group.

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ...
