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 ...

Orthoptera
Orthoptera () is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts, and close relatives; and Ensifera – crickets and close relatives. More than 20,000 species are distributed worldwide. The insects in the order have incomplete metamorphosis, and produce sound (known as a " stridulation") by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. The tympanum, or ear, is located in the front tibia in crickets, mole crickets, and bush crickets or katydids, and on the first abdominal segment in the grasshoppers and locusts. These organisms use vibrations to locate other individuals. Grasshoppers and other orthopterans are able to fold their wings (i.e. they are members of Neoptera).

Ghana
Ghana (; tw, Gaana, ee, Gana), officially the Republic of Ghana, is a country in West Africa. It abuts the Gulf of Guinea and the Atlantic Ocean to the south, sharing borders with Ivory Coast in Ghana–Ivory Coast border, the west, Burkina Faso in Burkina Faso–Ghana border, the north, and Togo in Ghana–Togo border, the east.Jackson, John G. (2001) ''Introduction to African Civilizations'', Citadel Press, p. 201, . Ghana covers an area of , spanning diverse biomes that range from coastal savannas to tropical rainforests. With nearly 31 million inhabitants (according to 2021 census), Ghana is the List of African countries by population, second-most populous country in West Africa, after Nigeria. The capital and List of cities in Ghana, largest city is Accra; other major cities are Kumasi, Tamale, Ghana, Tamale, and Sekondi-Takoradi. The first permanent state in present-day Ghana was the Bono state of the 11th century. Numerous kingdoms and empires emerged over the centuri ...

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 ...

Grasshopper
Grasshoppers are a group of insects belonging to the suborder Caelifera. They are among what is possibly the most ancient living group of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago. Grasshoppers are typically ground-dwelling insects with powerful hind legs which allow them to escape from threats by leaping vigorously. As hemimetabolous insects, they do not undergo complete metamorphosis; they hatch from an egg into a Nymph (biology), nymph or "hopper" which undergoes five moults, becoming more similar to the adult insect at each developmental stage. The grasshopper hears through the tympanal organ which can be found in the first segment of the abdomen attached to the thorax; while its sense of vision is in the compound eyes, the change in light intensity is perceived in the simple eyes (ocelli). At high population densities and under certain environmental conditions, some grasshopper species can change color and behavior and for ...

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 ...
