phorid fly life cycle

In January 2012, a researcher discovered larvae in the test tube of a dead honey bee believed to have been affected by colony collapse disorder. The strong, well developed radial (R) veins end in the costa about halfway along the wing. Many species of phorid flies are specialist parasitoids of ants, but several species in the tropics are parasitoids of stingless bees. The ratio of first, second, and third sections of the costa is often a reliable specific character. For this reason, they are important in forensic entomology. Disney, R.H.L. Of the radial veins, only R1 and R4+5 are developed. The subcosta is reduced. Here is a thumbnail outline: ... After a phorid fly has laid an egg into the thorax of a fire ant worker, the egg develops into a larva (maggot), which feeds on the body fluids and squeezes its way into the head space of the ant where it continues to feed. Only in the genus Megaselia is the hypandrium more or less distinctly separated from the epandrium. Because they frequent unsanitary places, including drain pipes, they may transport various disease-causing organisms to food material. The puparium is oval, pointed at ends (because the larval extremities remain relatively unchanged). What are phorid flies? How Long Do Phorid Flies Live? Eggs are laid on or beside moist decaying materials. The groups of bristles are developed on the head. The life cycle from egg to adult can be completed in as little as 14 days under warm, moist conditions, but may take as long as 37 days under cooler or less than optimum conditions. The female phorid fly will lay about 40 eggs over a 12 hour period. As mentioned, the creature’s life cycle is 25-days and can grow from zero to zillions in a short time. SIZE: Small flies one-eighth of an inch in length. [5][6][7] Further resolution of this controversy awaits new data. Infected bees act oddly, foraging at night and gathering around lights like moths. Eggs are laid . Many species of phorid flies are specialist parasitoids of ants, but several species in the tropics are parasitoids of stingless bees. The life cycle of this fly begins when the female lays eggs where there is actively growing mushroom mycelium, either in the wild or in commercial mushroom houses. Bonner zoologische Beiträge, 43, 145–154. & Cumming, M.S. K. G. V. Smith, 1989 An introduction to the immature stages of British Flies. The fly pupates in the detached head capsule, requiring a further two weeks before emerging. As they mature, they become whitish and reach a length of 4.5 mm. The female deposits 20 eggs at a time and can produce 40 eggs in a 12 hour period. COLOR: Tan-brown with black eyes; small head; a severely arched (humpbacked) thorax when viewed from the side. Under ideal conditions, the lifecycle can be completed in as little as 14 days or take as long as 37 days. Crossveins are totally absent. Pseudacteon are solitary parasitoids. R4+5 may furcate at end. [10][11] The native species of fire ants are also parasitized by some species of Pseudacteon; these native fire ants don't cause ecological damage the way introduced species do. Immediately before the ocellar callus are two preocellar bristles. They may be flat, swollen, or other. Phorid flies, family Phoridae Megaselia scalaris, the scuttle fly. Various species of Phoridae have been introduced throughout the southeast United States, starting with Travis, Brazos, and Dallas Counties in Texas, as well as Mobile, Alabama, where the non-native fire ants first entered North America. Pseudacteon species reproduce by laying eggs in the thorax of the ant. Phorid fly larvae feed … Whiteflies form a major threat for many vegetable and ornamental crops. Phorid flies develop from eggs into larval, and pupal stages before emerging as adults. The wings are clear or tinged only rarely with markings. T. L. Carpenter and D. O. Chastain: "Facultative Myiasis by, K. Komori, K. Hara, K.G.V. Segments VII and VIII of the male are more or less sclerotized in the genus Megaselia, but otherwise mostly membranous. The adult female inserts a single egg into a worker ant with a hypodermic-style ovipositor in a rapid aerial attack. The third antennal segment in some species is unique in shape. With maturity, they become whitish and are about 4.5 mm in length; end-to-end, about five and one-half larvae equal an inch. Depending on species, temperatures, and the hospitality of the environment, these pests spend 11 to 22 or more days to become adults. Medial veins are represented by M1, M2, and M4. Phorid flies need moisture to develop. The Phoridae show the greatest diversity of all the dipterous families. Another vernacular name, coffin fly, refers to Conicera tibialis. The Ohio State University says that drain flies lay their eggs anywhere where there are moist organic solids. The third segment of the antenna is large and rounded or elongated, and bears a long apical or dorsal arista directed sideways. Two pairs of supra-antenna1 bristles, sometimes one, are completely reduced. Journal of Natural History, 29, 1081–1082. When viewed from the side, a pronounced hump to the thorax is seen. In some genera, segments VII to X in the female are highly sclerotized and extended into a tube ("ovipositor"). Traditionally, phorids were classified into six subfamilies: Phorinae, Aenigmatiinae, Metopininae (including tribes Beckerinini and Metopinini), Alamirinae, Termitoxeniinae, and Thaumatoxeninae. Phorid fly (Phoridae) House-infesting flies. Phorid Fly Life Cycle. Borgmeier, T. 1963. [8], Other species, especially those of the giant genus Megaselia, develop in various fungi during their larval stage and may be pests of cultivated mushrooms.[9]. During the daytime, adults take rest in shadowy areas. The vertex is flat. The development of each life cycle depends on the environmental conditions in which the larva are feeding or being reared. (1993) Mosaic evolution and outgroup comparisons. Phorid flies develop from eggs into larval, and pupal stages before emerging as adults. Eggs are deposited on or near surfaces of decaying organic matter. Larvae are found in the nests of social insects and in some aquatic habitats, in organic detritus such as dung, carrion, insect frass, and dead snails. Phorid flies are often seen walking along a surface, rather than flying. 10 years ago. Nearctic: "Nomina Insecta Nearctica: Species and Genera Tables", https://en.wikipedia.org/w/index.php?title=Phoridae&oldid=991399944, Articles needing additional references from July 2016, All articles needing additional references, Creative Commons Attribution-ShareAlike License. The other veins (branches of the medius) are weaker and usually follow a diagonal course and are often parallel to each other. continue as a single vein to the end. A study by Stenchly et al. The Phorid fly life cycle is: egg, larvae, pupa and adult. Other common names for flies in this family include: humpbacked, coffin, and scuttle flies. Disney rejected the entirety of Brown's work, deeming it premature, and a lively debate ensued. Tergite 9 the (epandrium) is highly developed and usually fused at least on one side with the hypandrium (sternite 9). Advertisement. Life Cycle. The phorid fly's egg-to-adult life cycle can be as short as 14 days, but may take up to 37 days.
