Leafhopper
Leafhopper is the common name for any species from the family (biology), family Cicadellidae: based on the type genus ''Cicadella''. 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 Vector (epidemiology), 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 Auchenorrhy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typhlocybinae
Typhlocybinae is a subfamily of insects in the leafhopper, leafhopper family, Cicadellidae. This is currently the second largest leafhopper subfamily based on the number of described species, but researchers believe there are so many taxa yet undescribed that it is probably the largest subfamily.Dietrich, C. H. (2013)South American leafhoppers of the tribe Typhlocybini (Hemiptera: Cicadellidae: Typhlocybinae).''Zoologia (Curitiba)'' [online] 30(5) 519-68. Approximately 6000 species have been described thus far. Typhlocybinae belongs to the second-largest subfamily of leafhoppers, with >6,000 described extant species placed in ~300 genera and five tribe Many species of the subfamily Typhlocybinae are major pests of crops, such as cotton, grape, and eggplant, by direct or indirect damage (Oman, 1949, Vidano, 1962, Nielson, 1968, Zhang, 1990, Qin and Zhang, 2008). Tribes Entomologists divide the subfamily into four to ten tribes. Five tribes are generally accepted: *Alebrini *Dikra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holarctic
The Holarctic realm is a biogeographic realm that comprises the majority of habitats found throughout the continents in the Northern Hemisphere. It corresponds to the floristic Boreal Kingdom. It includes both the Nearctic zoogeographical region (which covers most of North America), and Alfred Wallace's Palearctic zoogeographical region (which covers North Africa, and all of Eurasia except for Southeast Asia, the Indian subcontinent, the southern Arabian Peninsula). These regions are further subdivided into a variety of ecoregions. Many ecosystems and the animal and plant communities that depend on them extend across a number of continents and cover large portions of the Holarctic realm. This continuity is the result of those regions’ shared glacial history. Major ecosystems Within the Holarctic realm, there are a variety of ecosystems. The type of ecosystem found in a given area depends on its latitude and the local geography. In the far north, a band of Arctic tun ...
