Aedes
A blood-sucking yellow fever mosquito (Aedes aegypti )
Aedes is a genus within the family of mosquitoes ( Culicidae ). Their main area of distribution are the tropics and subtropics, in Europe are only a few species native. The genus was up to the revisions of the tribe Aedini in the years 2000 to 2009 as a large collection genre in which almost all genres of Aedini were united.
The scientific name derives from the Greek word Aedes translated it means unpleasant or annoying, because the females of this genus in humans suck blood. They can function as an intermediary for pathogenic viruses, which act such as the dengue virus or yellow fever virus. Some species were abducted by people in other parts of the world, such as the Asian tiger mosquito (Aedes albopictus ) in the U.S. and Europe.
Features
The species of the genus Aedes ( Aedes gr ἀηδής, " unconstitutional " ) differ only slightly from those of other genera within the tribe Aedini. The females are highly variable in their appearance. The position of the compound eyes to each other varies from very close together lying to clearly separate. The front of the head and the face plate ( clypeus ) are either unbeschuppt or scaly. The palps have five or fewer members and three-quarters to one-tenth times as long as the proboscis. The antennae are slightly longer to significantly shorter than the proboscis. The mesonotum of the thorax is slightly to strongly curved, the tag ( scutellum ) is clearly lobed. The Postnotum is covered with bristles or unbeborstet. The bristles of the Mesonotums and the pleura varies just like the scales on the Mesonotums, the scutellum and pleurae. The fourth Tarsenglied of the legs is considerably longer than the fifth, the jaws are usually serrated. The tergites and sternites of the abdomen ( tummy) are covered with large scales, the abdomen end is usually pointed, sometimes blunt. The animals are different from those of other genera mainly by the absence or presence of bristles on various sclerites on the sides of the thorax.
The males are very similar to the females. Your differently segmented palps vary in length, as well as the sensors which are also hairiness. The jaw members are usually enlarged and formed differently to the respective pairs of legs. The front and middle pairs of legs are perforated. The segments 12 and 13 of the probe are usually extended flagellum.
System
The genus was described in 1818 with only one type Aedes cinereus by Johann Wilhelm Meigen. Meigen she called in his first description mosquitoes mosquito, this German -language name has, however, not enforced. By the end of the 20th century the genre had grown in many ways with heterogeneous features and was considered a " collective species". It was divided into 43 subgenera, according to recent studies, 32 of which were elevated to the genus rank. The systematic classification of the genera and subgenera within the whole tribe Aedini is not yet fully clarified. The following species occur in Europe:
- Aedes (Aedes ) cinereus Meigen, 1818
- Aedes (Aedes ) esoensis Dolbeskin, Goritzkaja & Mitrofanova, 1930
- Aedes (Aedes ) geminus Peus, 1970
- Aedes ( Aedimorphus ) vexans ( Meigen, 1830)
- Aedes ( Fredwardsius ) vittatus ( Bigot, 1861)
- Yellow fever mosquito Aedes ( Stegomyia ) aegypti (Linnaeus, 1762)
- Asian tiger mosquito Aedes ( Stegomyia ) albopictus ( Skuse, 1894)
- Aedes ( Stegomyia ) cretinus Edwards, 1921
