Glassy-winged Sharpshooter
The glassy-winged sharpshooter (''Homalodisca vitripennis'', formerly known as ''H. coagulata'') is a large leafhopper (family Cicadellidae), similar to other species of sharpshooter. Description These sharpshooters are about in length. Their color is dark brown to black with black-and-yellow undersides, with yellow eyes, and the upper parts of the head and back are speckled with ivory or yellowish spots. The wings are transparent with reddish veins.APHIS. 2002Glassy-winged Sharpshooter and Pierce's Disease in California They have piercing, sucking mouthparts and rows of fine spines on their hind legs. Distribution It is native to North America (northeastern Mexico), but it was accidentally introduced into Southern California in the early 1990s, probably with ornamental or agricultural stock. There it has become an agricultural pest especially to viticulture. Glassy-winged sharpshooters usually lay a mass of eggs on the underside of leaves, and they cover them with powdery ...

Ernst Friedrich Germar
Ernst Friedrich Germar (3 November 1786 – 8 July 1853) was a German professor and director of the Mineralogical Museum at Halle. As well as being a mineralogist he was interested in entomology and particularly in the Coleoptera and Hemiptera. He monographed the heteropteran family Scutelleridae. In 1845, he was elected a foreign member of the Royal Swedish Academy of Sciences. Published works Amongst Germar's publications are: *Species Cicadarium enumeratae et sub genera distributae. ''Thon's Entomologisches Archiv''. (2)2: 37–57, pl. 1 (1830). *Observations sur plusieurs espèces du genre Cicada, ''Latr. Rev. Entomol.

Integrated Pest Management
Integrated pest management (IPM), also known as integrated pest control (IPC) is a broad-based approach that integrates both chemical and non-chemical practices for economic control of pests. IPM aims to suppress pest populations below the economic injury level (EIL). The UN's Food and Agriculture Organization defines IPM as "the careful consideration of all available pest control techniques and subsequent integration of appropriate measures that discourage the development of pest populations and keep pesticides and other interventions to levels that are economically justified and reduce or minimize risks to human health and the environment. IPM emphasizes the growth of a healthy crop with the least possible disruption to agro-ecosystems and encourages natural pest control mechanisms." Entomologists and ecologists have urged the adoption of IPM pest control since the 1970s. IPM allows for safer pest control. The introduction and spread of invasive species can also be managed wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Hemiptera Of North America
Hemiptera (; ) is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking 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 ants, bees, beetles, or butterflies. In some variations of English, all terrestrial arthropods (including non-insect arachnids, and myriapods) also fall under the colloquial understanding of ''bug''. Many insects with "bug" in their common name, especially in American English, belong to other orders; for example, the lovebug is a fly and the Maybug and ladybug are beetles. The term is also occa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proconiini
The name sharpshooter is used to refer to any of various genera and species of large leafhoppers in the tribe Proconiini of the family leafhopper, Cicadellidae. As with all cicadellids, they have piercing-sucking mouthparts and closely spaced rows of fine spines on their hind legs. The nymphs feed by inserting their needle-like mouthparts into the xylem of the small stems on the plant where the eggs were deposited; the adults have wings and are highly mobile, and most feed on a variety of different plant species. Both nymphs and adults filter a huge volume of dilute liquid through their Digestion#Digestive system, digestive system to extract the trace nutrients, and much of the water and carbohydrates are squirted forcibly away from the body in a fine stream of droplets, thus earning them their common name. This group includes a few species which are plant pests, the most serious of which is ''Homalodisca vitripennis'' (the "Glassy-winged sharpshooter"). A microbial plant parasit ...

United States National Agricultural Library
The United States National Agricultural Library (NAL) is one of the world's largest agricultural research libraries, and serves as a national library of the United States and as the library of the United States Department of Agriculture. Located in Beltsville, Maryland, it is one of five national libraries of the United States (along with the Library of Congress, the National Library of Medicine, the National Transportation Library, and the National Library of Education).

Virology (journal)
''Virology'' is a peer-reviewed scientific journal in virology. Established in 1955 by George Hirst, Lindsay Black and Salvador Luria, it is the earliest English-only journal to specialize in the field. The journal covers basic research into viruses affecting animals, plants, bacteria and fungi, including their molecular biology, structure, assembly, pathogenesis, immunity, interactions with the host cell, evolution and ecology. Molecular aspects of control and prevention are also covered, as well as viral vectors and gene therapy, but clinical virology is excluded. As of 2013, the journal is published fortnightly by Elsevier. History The field of virology began in the 1890s, with the discovery of infectious agents small enough to pass through filters sufficiently fine to catch bacteria. The first specialist journal in the field, ''Archiv für die gesamte Virusforschung'', appeared in 1939. Published by Springer-Verlag out of its Vienna office, its papers were in a mixture of lan ...

Dicistroviridae
''Dicistroviridae'' is a family of viruses in the order ''Picornavirales''. Invertebrates, including aphids, leafhoppers, flies, bees, ants, and silkworms, serve as natural hosts. There are 15 species in this family, assigned to three genera. Diseases associated with this family include: DCV: increased reproductive potential. extremely pathogenic when injected with high associated mortality. CrPV: paralysis and death. Taxonomy Although many dicistroviruses were initially placed in the ''Picornaviridae'', they have since been reclassified into their own family. The name (Dicistro) is derived from the characteristic dicistronic arrangement of the genome. This family is a member of the Order ''Picornavirales'' (along with the families ''Iflaviridae'', ''Picornaviridae'', and ''Secoviridae'' and '' Marnaviridae''). Within this order, the gene order is the gene order of the nonstructural proteins Hel(helicase)-Pro(protease)-RdRp(polymerase). The ''Dicistroviridae'' can be disting ...
