The name Diptera, derived from the Greek words "di" meaning two and "ptera" meaning wings, refers to the fact that true flies have only a single pair of wings. Larvae are found in all fresh water, semi-aquatic, and moist terrestrial environments. The order Diptera includes all true flies.
The diverticulated crop is a unique and overlooked foregut organ in the Diptera that affects many physiological and behavioral functions. Historically, the crop was viewed simply as a reservoir for excess nutrients. The crop lobes and crop duct form an elaborate sphincter and pump system that moves stored nutrients to the crop lobes, oral cavity, and the midgut.
Diptera: flies and mosquitoes. Characteristics This is one of the largest insect orders in the world and includes many familiar insects such as mosquitoes, midges, sand flies, house flies and blowflies. Many species of Diptera are important due to the role they play in disease transmission, which includes such things as mosquitoes that spread malaria in many underdeveloped countries.
Dipteranorder Dipteraany member of an order of insects containing the two-winged or so-called true flies. Although many winged insects are commonly called flies, the name is strictly applicable only to members of Diptera. One of the largest insect orders, it numbers more thanspecies that are relatively small, with soft bodies.
The Diptera is a very large and diverse order of mostly small to medium-sized insects. They have prominent compound eyes on a mobile head, and at most one pair of functional, membraneous wings,  which are attached to a complex mesothorax. The second pair of wings, on the metathorax, are reduced to halteres.
Veterinary Entomology pp Cite as. The Diptera are the true flies. In most of the orders of winged insect, adults have two pairs of wings.
Key to the adults of the most common forensic species of Diptera in South America. Flies Diptera, blow flies, house flies, flesh flies, horse flies, cattle flies, deer flies, midges and mosquitoes are among the four megadiverse insect orders. Several species quickly colonize human cadavers and are potentially useful in forensic studies.
Quantitative laboratory bioassay methods are required to evaluate the toxicity of novel insecticidal compounds for pest control and to determine the presence of resistance traits. We used a radioactive tracer based on 32 P-ATP to estimate the volume of a droplet ingested by two dipteran pests: Ceratitis capitata Tephritidae and Drosophila suzukii Drosophilidae. Using blue food dye it was possible to distinguish between individuals that ingested the solution from those that did not.
The Museum's 2. The international collection holds important Diptera type material, most notably of taxa described by Walker, Bigot, Brunetti, Edwards and Austen. Some of this type material dates back to the eighteenth century.
