James Waterston (entomologist)
James Waterston (7 February 1879 – 28 April 1930) was a Scottish entomologist and minister of the United Free Church of Scotland who in 1917 was appointed as the first specialist hymenopterist at the Imperial Bureau of Entomology. James Waterson was born on 7 February 1879 in Paisley, Renfrewshire, Scotland, and was educated as George Watson's College in Edinburgh before studying Divinity and Science at the University of Edinburgh, graduating with bachelor's degrees in both subjects, before being awarded a doctoral degree in science. He became a minister of the United Free Church in Shetland where he continued his biological studies, carrying out studies of ectoparasites, becoming an authority in the Mallophaga of Britain. In 1917 Waterston joined the Imperial Bureau of Entomology to study the Hymenoptera of the superfamily Chalcidoidea. He was temporarily commissioned in the Royal Army Medical Corps in May 1917 and served as entomologist to the Malaria Commission at Thessal ...

Chalcid Wasp
Chalcid wasps (, , for their metallic colour) are insects within the superfamily Chalcidoidea, part of the order Hymenoptera. The superfamily contains some 22,500 known species, and an estimated total diversity of more than 500,000 species, meaning the vast majority have yet to be discovered and described. The name "chalcid" is often confused with the name "chalcidid", though the latter refers strictly to one constituent family, the Chalcididae, rather than the superfamily as a whole; accordingly, most recent publications (e.g.,) use the name "chalcidoid" when referring to members of the superfamily. Most chalcid wasps are parasitoids of other insects, though other life styles are known, with the herbivorous fig wasps acting as pollinators. Various species are used as biological pest control agents or in scientific research. Description Chalcidoids are generally small wasps, averaging 1.5 mm in length and usually being less than 3 mm. The body is often metallic in colour. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphelinidae
The Aphelinidae are a moderate-sized family of tiny parasitic wasps, with about 1100 described species in some 28 genera. These minute insects are challenging to study, as they deteriorate rapidly after death unless extreme care is taken (e.g., preservation in ethanol), making identification of most museum specimens difficult. The larvae of the majority are primary parasitoids on Hemiptera, though other hosts are attacked, and details of the life history can be variable (e.g., some attack eggs, some attack pupae, and others are hyperparasites). Males and females may have different hosts and different life historie They are found throughout the world in virtually all habitats, and are extremely important as biological control agents. The oldest fossils are known from the Eocene aged Baltic Amber. They are difficult to separate from other Chalcidoidea except by subtle features of the wing venation and other difficult characters, and the family appears to be paraphyletic, so is ...

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Parasitoid
In evolutionary ecology, a parasitoid is an organism that lives in close association with its host (biology), host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionarily stable strategy, evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation. Among parasitoids, strategies range from living inside the host (''endoparasitism''), allowing it to continue growing before emerging as an adult, to Paralysis, paralysing the host and living outside it (''ectoparasitism''). Hosts can include other parasitoids, resulting in hyperparasitism; in the case of oak galls, up to five levels of parasitism are possible. Some parasitoids Behavior-altering parasite, influence their host's behaviour in ways that favour the propagation of the parasitoid. Parasitoids are found in a variety of Taxon, taxa across the insect superorder Endopterygota, whose compl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scale Insect
Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as honeydew on which sooty mold tends to grow. The insects often have a mutualistic relationship with ants, which feed on the honeydew and protect them from predators. There are about 8,000 descr ...

Coccidae
The Coccidae are a family of scale insects belonging to the superfamily Coccoidea. They are commonly known as soft scales, wax scales or tortoise scales. The females are flat with elongated oval bodies and a smooth integument which may be covered with wax. In some genera they possess legs but in others, they do not, and the antennae may be shortened or missing. The males may be winged or wingless. Genera There are >1,100 spp. in 171 genera worldwide. *Subfamily Myzolecaniinae ** '' Akermes'' ** '' Alecanium'' ** '' Alecanopsis'' ** '' Cribolecanium'' ** '' Cryptostigma'' ** '' Cyclolecanium'' ** '' Halococcus'' ** '' Houardia'' ** '' Megasaissetia'' ** '' Myzolecanium'' ** '' Neolecanium'' ** '' Paractenochiton'' ** '' Pseudophilippia'' ** '' Richardiella'' ** '' Torarchus'' ** '' Toumeyella'' ** '' Xenolecanium'' * '' Antecerococcus'' * '' Ceroplastes'' * ''Coccus A coccus (plural cocci) is any bacterium or archaeon that has a spherical, ovoid, or generally round shap ...

Hymenoptera Of Asia
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
