Diachasmimorpha Mellea
''Diachasmimorpha mellea'' (formerly known as ''Biosteres melleus'') is a species of braconid parasitoid wasp which attacks multiple species of ''Rhagoletis'' fruit flies, including ''R. pomonella'', the apple maggot fly. This wasp has been found throughout much of the United States and in Central Mexico. It is morphologically similar to and has overlapping range with another apple maggot parasitoid, ''Diachasma alloeum ''Diachasma alloeum'' is a small wasp in the family Braconidae. It is a parasitoid of ''Rhagoletis pomonella'', the apple maggot. The wasp lays its eggs into third-instar larvae of the fly, which then develop after the larvae have pupated. Th ...''.

Charles Joseph Gahan
Charles Joseph Gahan (20 January 1862 – 21 January 1939) was an Irish entomologist who specialized in beetles, particularly the Cerambycidae. He served as keeper at the department of entomology in the British Museum (Natural History) for thirteen years after Charles Owen Waterhouse. He was born at Roscrea, County Tipperary, Ireland. His father, Michael Gahan was the Master of Erasmus Smith's School in Tipperary. He was educated first at Queens College Galway, where he achieved distinction, and then at the Royal School of Mines in Kensington. In 1882 he was awarded a medal and prizes as the best biological student of the session. In 1886, he joined the British Museum (Natural History) as an assistant in the Department of Zoology where he became Keeper in the then newly formed Department of Entomology in 1913. An expert on beetles, especially Cerambycidae, he wrote the 1906 volume of ''The Fauna of British India, Including Ceylon and Burma'' on that group. Gahan served as honorar ...

Parasitoid Wasp
Parasitoid wasps are a large group of hymenopteran superfamilies, with all but the wood wasps (Orussoidea) being in the wasp-waisted Apocrita. As parasitoids, they lay their eggs on or in the bodies of other arthropods, sooner or later causing the death of these hosts. Different species specialise in hosts from different insect orders, most often Lepidoptera, though some select beetles, flies, or bugs; the spider wasps (Pompilidae) exclusively attack spiders. Parasitoid wasp species differ in which host life-stage they attack: eggs, larvae, pupae, or adults. They mainly follow one of two major strategies within parasitism: either they are endoparasitic, developing inside the host, and koinobiont, allowing the host to continue to feed, develop, and moult; or they are ectoparasitic, developing outside the host, and idiobiont, paralysing the host immediately. Some endoparasitic wasps of the superfamily Ichneumonoidea have a mutualistic relationship with polydnaviruses, the vir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhagoletis
''Rhagoletis'' is a genus of tephritid fruit flies with about 70 species. Name The genus name is partially derived from Ancient Greek ''rhago'' "a kind of spider". This possibly refers to the fact that at least '' R. pomonella'' mimics a jumping spider.

Apple Maggot
The apple maggot (''Rhagoletis pomonella''), also known as the railroad worm (but distinct from the '' Phrixothrix'' beetle larva, also called railroad worm), is a species of fruit fly, and a pest of several types of fruits, especially apples. This species evolved about 150 years ago through a sympatric shift from the native host hawthorn to the domesticated apple species ''Malus domestica'' in the northeastern United States. This fly is believed to have been accidentally spread to the western United States from the endemic eastern United States region through contaminated apples at multiple points throughout the 20th century. The apple maggot uses Batesian mimicry as a method of defense, with coloration resembling that of the forelegs and pedipalps of a jumping spider (family Salticidae). The adult form of this insect is about long, slightly smaller than a housefly. The larva, which is the stage of this insect's lifecycle that causes the actual damage to the fruit, is similar ...

Diachasma Alloeum
''Diachasma alloeum'' is a small wasp in the family Braconidae. It is a parasitoid of ''Rhagoletis pomonella'', the apple maggot. The wasp lays its eggs into third-instar larvae of the fly, which then develop after the larvae have pupated. The immature wasps then eat the fly larvae and overwinter inside the fly puparia. ''D. alloeum'' wasps attacking ''R. pomonella'' in apples appear to be undergoing a speciation event in concert with their hosts. This is an example of sequential sympatric speciation Sympatric speciation is the evolution of a new species from a surviving ancestral species while both continue to inhabit the same geographic region. In evolutionary biology and biogeography, sympatric and sympatry are terms referring to organi ....

Braconidae
The Braconidae are a family of parasitoid wasps. After the closely related Ichneumonidae, braconids make up the second-largest family in the order Hymenoptera, with about 17,000 recognized species and many thousands more undescribed. One analysis estimated a total between 30,000 and 50,000, and another provided a narrower estimate between 42,000 and 43,000 species. Classification The Braconidae are currently divided into about 47 subfamilies and over 1000 genera, which include ''Aerophilus'', ''Aleiodes'', '' Apanteles'', ''Asobara'', '' Bracon'', ''Cenocoelius'', '' Chaenusa'', ''Chorebus'', '' Cotesia'', '' Dacnusa'', '' Diachasma'', ''Microgaster'', ''Opius'', ''Parapanteles'', '' Phaenocarpa'', ''Spathius'', and ''Syntretus.'' These fall into two major groups, informally called the cyclostomes and noncyclostomes. In cyclostome braconids, the labrum and the lower part of the clypeus are concave with respect to the upper clypeus and the dorsal margin of the mandibles. The ...

Insects Described In 1915
Insects (from Latin ') are pancrustacean Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes and one pair of antenna (biology), antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of Extant taxon, extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all Natural environment, environments, although only a small number of species reside in the oceans, which are dominated by ...
