Orthopterology
Orthopterology is the scientific study of the order Orthoptera, which includes grasshoppers, crickets, locusts and some other insects. Someone that studies in this field is an orthopterist. The term is derived from the Ancient Greek words and , meaning ''straight'' and ''wing'' respectively, with the English suffix ''-logy''.This ultimately derives from Greek , but via Latin ''-logia'' and French ''-logie''. Orthopterology as a science A notable branch of orthopterology is , which focuses on locusts and grasshoppers in the family Acrididae and is relevant to famine prevention. Orthopterological societies * Association for Applied Acridology International * Orthopterists' Society * German Society for Orthopterology Orthopterological Journals * Journal of Orthoptera Research See also * LUBILOSA LUBILOSA was the name of a research programme that aimed at developing a biological alternative to the chemical control of locusts. This name is an acronym of the French title of th ...

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). Etymology The name is derived from the Greek ὀρθό ...

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 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 form swarms. Under ...

Cricket (insect)
Crickets are orthopteran insects which are related to bush crickets, and, more distantly, to grasshoppers. In older literature, such as Imms,Imms AD, rev. Richards OW & Davies RG (1970) ''A General Textbook of Entomology'' 9th Ed. Methuen 886 pp. "crickets" were placed at the family level (''i.e.'' Gryllidae), but contemporary authorities including Otte now place them in the superfamily Grylloidea. The word has been used in combination to describe more distantly related taxa in the suborder Ensifera, such as king crickets and mole crickets. Crickets have mainly cylindrically-shaped bodies, round heads, and long antennae. Behind the head is a smooth, robust pronotum. The abdomen ends in a pair of long cerci; females have a long, cylindrical ovipositor. Diagnostic features include legs with 3-segmented tarsi; as with many Orthoptera, the hind legs have enlarged femora, providing power for jumping. The front wings are adapted as tough, leathery elytra, and some crickets ...

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 migratory) ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ...

-logy
''-logy'' is a suffix in the English language, used with words originally adapted from Ancient Greek ending in ('). The earliest English examples were anglicizations of the French '' -logie'', which was in turn inherited from the Latin '' -logia''. The suffix became productive in English from the 18th century, allowing the formation of new terms with no Latin or Greek precedent. The English suffix has two separate main senses, reflecting two sources of the suffix in Greek: *a combining form used in the names of school or bodies of knowledge, e.g., ''theology'' (loaned from Latin in the 14th century) or ''sociology''. In words of the type ''theology'', the suffix is derived originally from (''-log-'') (a variant of , ''-leg-''), from the Greek verb (''legein'', 'to speak')."-logy." ''The Concise Oxford Dictionary of English Etymology''. Oxford University Press, 1986. retrieved 20 August 2008. The suffix has the sense of "the character or deportment of one who speaks or treat ...

Acrididae
The AcrididaeMacLeay WS (1821) ''Horae Entomologicae or Essays on the Annulose Animals'' 2 are the predominant family of grasshoppers, comprising some 10,000 of the 11,000 species of the entire suborder Caelifera. The Acrididae are best known because all locusts (swarming grasshoppers) are of the Acrididae. The subfamily Oedipodinae is sometimes classified as a distinct family Oedipodidae in the superfamily Acridoidea. Acrididae grasshoppers are characterized by relatively short and stout antennae, and tympana on the side of the first abdominal segment. Subfamilies The ''Orthoptera Species File'' (September 2021) lists the following subfamilies of Acrididae. The numbers of genera and species are approximate and may change over time. # Acridinae MacLeay, 1821 (140 genera, 470 species), Worldwide: temperate and tropical # Calliptaminae Jacobson, 1905 (12 genera, 90 species), Africa, Europe, Asia # Caryandinae Yin & Liu, 1987 (3 genera, 100 species), Africa, Asia ## ''C ...

Orthopterists' Society
The Orthopterists' Society (formerly the Pan American Acridological Society) is an international scientific organization devoted to facilitating communication and research among persons interested in Orthoptera and related organisms. (The Orthoptera include grasshoppers, locusts, crickets, katydids and other insects.) The Society currently has 330 members from 43 countries on six continents. The journal publishes papers on all aspects of the biology of these insects from ecology and taxonomy to physiology, endocrinology, cytogenetics, and control measures. The Society publishes the refereed biannual ''Journal of Orthoptera Research''. The Society was founded in 1976 by some 35 orthopterists who met at San Martín de los Andes, Argentina. Its Constitution and Bylaws were adopted in 1977, and it was accorded tax-exempt status by the United States government in 1978. The meetings held since San Martín have been at Bozeman (US), Maracay, (Venezuela), Saskatoon (Canada), Valsaín (Spa ...
