Common Brown Leafhopper
The common brown leafhopper, ''Orosius orientalis'' (Matsumura) ( Hemiptera: Cicadellidae) is one of the most common species of Australian leafhoppers with a very wide host range. It is an important vector of several viruses and phytoplasmas worldwide. In Australia, phytoplasmas vectored by ''O. orientalis'' cause a range of economically important diseases including legume little leaf, tomato big bud, lucerne witches broom, potato purple top wilt, Australian lucerne and the insect is a possible vector of Australian grapevine yellows. ''O. orientalis'' also transmits Tobacco yellow dwarf virus (TYDV genus Mastrevirus, family Geminiviridae ''Geminiviridae'' is a family of plant viruses that encode their genetic information on a circular genome of single-stranded (ss) DNA. There are 520 species in this family, assigned to 14 genera.

With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

Orosius (genus)
''Orosius'' is a genus of leafhopper in the tribe Opsiini and the subfamily Deltocephalinae. The genus was revised by Ghauri in 1966. Species can be differentiated by the shape of the aedeagus An aedeagus (plural aedeagi) is a reproductive organ of male arthropods through which they secrete sperm from the testes during copulation with a female. It can be thought of as the insect equivalent of a mammal's penis, though the comparison .... Species There are seven known species including: * '' Orosius albicinctus'' Distant: type species * '' Orosius canberrensis'' (Evans, 1938), Australia * '' Orosius lotophagorum'' (Kirkaldy, 1907), Australia * '' Orosius orientalis'' (Evans, 1938), the common brown leafhopper, Australia References External links Orosius on www1.dpi.nsw.gov.au Cicadellidae genera Opsiini {{Deltocephalinae-stub ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geminiviridae
''Geminiviridae'' is a family of plant viruses that encode their genetic information on a circular genome of single-stranded (ss) DNA. There are 520 species in this family, assigned to 14 genera. Diseases associated with this family include: bright yellow mosaic, yellow mosaic, yellow mottle, leaf curling, stunting, streaks, reduced yields. They have single-stranded circular DNA genomes encoding genes that diverge in both directions from a virion strand origin of replication (i.e. geminivirus genomes are ambisense). According to the Baltimore classification they are considered class II viruses. It is the largest known family of single stranded DNA viruses. Mastrevirus and curtovirus Transmission (medicine), transmission is via various leafhopper species (e.g. maize streak virus and other African streak viruses are transmitted by ''Cicadulina mbila''), the only known topocuvirus species, ''Tomato pseudo-curly top virus'', is transmitted by the treehopper ''Micrutalis malleifera'', ...

Mastrevirus
''Mastrevirus'' is a genus of ssDNA viruses, in the family ''Geminiviridae''. Mostly monocotyledonous plants serve as natural hosts. They are vectored by planthoppers. There are 45 species in this genus. Diseases associated with this genus include: maize streak virus: maize streak disease (MSD). Capsid proteins ''Mastreviruses'' have an unusually diverse range of capsid proteins among the Geminiviridae. While all other genus, genera have species with essentially identical proteins (and their producing genetic sequences) among themselves, ''Mastrevirus'' has seven protein clusters and three species that each constitute their own. Taxonomy The following species are recognized: *''Axonopus compressus streak virus'' (ACSV) *''Bromus catharticus striate mosaic virus'' *''Camellia chlorotic dwarf-associated virus'' (CaCDaV) *''Citrus chlorotic dwarf-associated virus'' (CCDaV) *''Chickpea chlorosis Australia virus'' *''Chickpea chlorosis virus'' *''Chickpea chlorotic dwarf virus'' *'' ...

Leafhopper
A leafhopper is the common name for any species from the family Cicadellidae. These minute insects, colloquially known as hoppers, are plant feeders that suck plant sap from grass, shrubs, or trees. Their hind legs are modified for jumping, and are covered with hairs that facilitate the spreading of a secretion over their bodies that acts as a water repellent and carrier of pheromones. They undergo a partial metamorphosis, and have various host associations, varying from very generalized to very specific. Some species have a cosmopolitan distribution, or occur throughout the temperate and tropical regions. Some are pests or vectors of plant viruses and phytoplasmas. The family is distributed all over the world, and constitutes the second-largest hemipteran family, with at least 20,000 described species. They belong to a lineage traditionally treated as infraorder Cicadomorpha in the suborder Auchenorrhyncha, but as the latter taxon is probably not monophyletic, many modern au ...

Shōnen Matsumura
was a Japanese entomologist. Born in Akashi, Hyōgo, Dr. Shōnen Matsumura established Japan's first course on entomology at Hokkaido University. The courses were both applied (on insects of importance in forestry and agriculture) and theoretical. He named over 1,200 species of Japanese insects and in 1926 he founded the entomological journal ''Insecta Matsumurana.'' Matsumura wrote many scientific papers and books including ''6,000 illustrated Insects of Japan-Empire'' (1931). He died in Tokyo. His collection is in Hokkaido University in Sapporo.

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.
