Nomadacris
The red locust (''Nomadacris septemfasciata'') is a large grasshopper species found in sub-Saharan Africa. Its name refers to the colour of its hind wings. It is sometimes called the ''criquet nomade'' in French, due to its nomadic movements in the dry season. When it forms swarms, it is described as a locust. ''Nomadacris septemfasciata'' is in the family Acrididae and is the only member of the genus ''Nomadacris''. The genus ''Nomadacris'' was erected in 1923 by Boris Uvarov and the species was named originally as ''Acridium septemfasciatum'' by Jean Guillaume Audinet-Serville in 1838. It is placed in the subfamily Cyrtacanthacridinae, the bird locusts. Other species previously placed in ''Nomadacris'' are now considered part of the genus '' Patanga''. Description Adults The overall colour of adult insects is a mixture of light beige and brown. They have seven brown transverse bands on the elytra, justifying the species name ''septemfasciata''. The pronotum has two brown l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locust
Locusts (derived from the Vulgar Latin ''locusta'', meaning grasshopper) are various species of short-horned grasshoppers in the family Acrididae that have a swarming phase. These insects are usually solitary, but under certain circumstances they become more abundant and change their behaviour and habits, becoming gregarious. No taxonomic distinction is made between locust and grasshopper species; the basis for the definition is whether a species forms swarms under intermittently suitable conditions; this has evolved independently in multiple lineages, comprising at least 18 genera in 5 different acridid subfamilies. Normally, these grasshoppers are innocuous, their numbers are low, and they do not pose a major economic threat to agriculture. However, under suitable conditions of drought followed by rapid vegetation growth, serotonin in their brains triggers dramatic changes: they start to breed abundantly, becoming gregarious and nomadic (loosely described as migrator ...

Cyrtacanthacridinae
The Cyrtacanthacridinae are a subfamily of Orthoptera: Caelifera in the family Acrididae. They are sometimes referred-to as bird locusts, ''criquets voyageurs'' in French-speaking Africa, and ''Knarrschrecken'' in German. It includes species of locusts, short-horned grasshoppers that undergo phase polymorphism and are among the most important pests of sub-Saharan Africa; they include the desert locust and the red locust, with the related Bombay locust in Asia. One of the characteristics of members of this subfamily is the prominent peg between the forelegs: hence the name for the Australian Spur-throated locust. Genera The following genera have been included with a single tribe separated: Cyrtacanthacridini Auth. Kirby, 1910; worldwide distribution (mostly tropical and sub-tropical) # ''Anacridium'' Uvarov, 1923 # ''Chondracris'' Uvarov, 1923 # ''Cyrtacanthacris'' Walker, 1870 # ''Nomadacris'' Uvarov, 1923 - monotypic ''N. septemfaciata'' # ''Ornithacris'' Uvarov, 1924 ...

Patanga (grasshopper)
''Patanga'' is a genus of grasshoppers in the subfamily Cyrtacanthacridinae. Species are distributed throughout Asia: from India, China, Japan, Indochina and western Malesia. The genus was named by Boris Uvarov in 1923, with the type species the economically significant ''Patanga succincta, Bombay locust'': which has also been placed in genus ''Nomadacris''.

Boris Uvarov
Sir Boris Petrovitch Uvarov (3 November 1886 – 18 March 1970) was a Russian-British entomologist best known for his work on the biology and ecology of locusts. He has been called the father of acridology. Biography Boris Petrovitch Uvarov was born in Ural'sk, in the Russian Empire (now Oral, Kazakhstan), the youngest of three sons of Pyotr P. Uvarov, a state bank employee, and his wife, Aleksandra. His interest in natural history was aided in young life by his father's gift of six volumes of Brehm's ''Tierleben''. He went to a school in Uralsk from 1895 to 1902 where he was encouraged by S. M. Zhuravlev. He then studied briefly at the School of Mining at Ekaterinoslav (now Dnepropetrovsk) but transferred in 1906 to study biology in the Saint Petersburg State University, graduating in 1910. He was influenced by the teachings of Shimkevitch, Wagner, and Palladin but enjoyed most the meetings of the Russian Entomological Society where he was influenced by, among others, D. N. Bo ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Having a hot semi-arid climate, it stretches across the south-central latitudes of Northern Africa between the Atlantic Ocean and the Red Sea. The Sahel part of Africa includes – from west to east – parts of northern Senegal, southern Mauritania, central Mali, northern Burkina Faso, the extreme south of Algeria, Niger, the extreme north of Nigeria, Cameroon and Central African Republic, central Chad, central and southern Sudan, the extreme north of South Sudan, Eritrea and Ethiopia. Historically, the western part of the Sahel was sometimes known as the Sudan region (''bilād as-sūdān'' "lands of the Sudan"). This belt was located between the Sahara and the coastal areas of West Africa. There are frequent shortages of food and water due to the dry ha ...
