A mosquito, the adult body black or brown, ringed with white feet, wings without spots, stopped the plane parallel to the body and stay. Larvae and pupae grown in pots and other tree hole or cylinder in water, eggs scattered submerged in the bottom. Is the spread of diseases such as epidemic encephalitis B media. Also known as "black stripe."

Aedes aedes; aedine mosquitoes Culicidae Aedes mosquito subfamily known. Distribution of the world, is one of the largest Culicidae are nearly 1,000 species. China has more than 100 species. Aedes breeding in tree holes and more, bamboo, leaf liquid, cylinder tank, caves, potholes and other small water, some species in the rice fields, marshes, ponds grow. Egg yield, usually produced in the wet container wall or on the breeding places of the wet soil. Diapause eggs and low temperature drying, and thus spend the winter or dry season. In nature, a flood is only part of the mosquito eggs hatch, the remaining two or more times shall be subject to flooding to hatch. It is believed that this is easy to adapt to dry water containers. More active larvae in the water, scraping food materials on or attached to the bottom of the flooded lower organisms or other organic matter; a few types, such as mold mosquito subgenus larvae meat. Day or night blood-sucking female mosquitoes. Aedes mosquitoes bite mostly ferocious vampire who stabbed, while others are yellow fever, dengue and other arboviruses communicator, a few media types is filariasis. China Aedes species in the more important are: Aedes aegypti, Aedes albopictus, Aedes and stab Togo interference albopictus. In addition, harassment on the back point of mosquito Aedes subgenus, yellow albopictus, barbed stinger and sting Aedes albopictus are fierce vampire who, in their place a lot of places, a great disturbance to humans and animals. Media albopictus, known 12 kinds of mosquito can transmit the disease, but most of Aedes aegypti and Aedes albopictus. Guangdong, Guangxi, and more for the spread of Aedes albopictus, the Leizhou Peninsula, coastal areas, Guangxi, Hainan Province and Southeast Asia, mainly in Aedes aegypti. Aedes as long as the liquid contact with an infectious, you can get infected, the virus in mosquitoes copy 8--14 days after contagious, infectious period of the elderly up to 174 days. Human infectious Aedes mosquito, the virus will spread to humans. Captured by the mosquito ovary detected dengue virus particles, suggesting that the virus may be stored Aedes host. Yunnan Province, four kinds of mosquito encephalitis virus isolates of 9 counties in Yunnan Province, southwestern border to capture the female Aedes mosquito 16 kinds of 19367, with the cell separation method and the rat virus. 6491 from 185 batches of Aedes albopictus in the two viruses isolated from 50 batch 1605 assassination of the virus isolated from Aedes disturbance 2, 772 grant from 23 narrow-winged mosquito virus 2 was isolated from 4 batch of 103 viruses isolated from Aedes Assam 1. Other 12 mosquito species were 10 396 virus isolates were negative. The seven strains isolated by immunofluorescence, enzyme immunoassay, hemagglutination inhibition and neutralization tests identified, both encephalitis virus (je virus). Aedes albopictus, a mosquito species of wild bamboo advantage. Analysis of Aedes albopictus in the local preservation and dissemination of JE virus plays an important role, gill scrambling albopictus, narrow wings Aedes albopictus and Assam also involved in the spread of the virus. Home and abroad in encephalitis (JE for short) a lot of work in media studies, specifically the Culex tritaeniorhynchus (culex tritaeniorhynchus) is the main media of the disease, a number of Culex mosquitoes in the spread of JE virus has also played an important role. However, the spread of the disease Aedes in the role of less. The other 12 kinds of mosquito (Aedes albopictus pseudo-ae. Pseudalbopictus, round spots Aedes ae. Annandalei, Taiwan Aedes ae. Formosensis, significant Aedes ae. Prominens, share point simulation subspecies Aedes ae. Gardnerii imitator, white Snow Aedes ae. niveus, white light Aedes ae. alboscutellatus, ring shank Aedes ae. desmotes, the white side of Aedes ae. albolateralis, vaginal Mickey Air Asia species Aedes ae. albotaeniatus mikiranus, love's Aedes ae. eldridgei and sub Aedes albopictus ae. subalbopictus) Four kinds of distribution of Aedes Aedes albopictus in the nine counties of this survey are distributed, the ecological environment of their activities, mainly in _set_tlements near the bamboo forest bamboo forest and hills, livestock and people circle the room almost can not catch the mosquito. Aedes albopictus in the wild bamboo forest area constitutes 30.46% ratio (7429 / 45 kinds of 24387), an advantage or more dominant species. Aedes interference only in the assassination of Jinghong, Mongla, Gengma and estuaries capture, mainly distributed in the wild bamboo forests, the habitat composition ratio of 12.71% (1194 / 17 kinds of 9394); also in the distribution of livestock pens, constitute more than 1.26% (428 / 20 kinds of 33929). Aedes narrow wings in Jinghong, Gengma, Ruili and Yingjiang of livestock and wild bamboo rings are distributed, the composition of livestock pens than 2.89% (696 / 24 060 19 kinds), wild bamboo (Gengma) of composition ratio of 2.75% (76 / 24 kinds of 2760), their number less. Assam Aedes Gengma and Luxi only catch the wild bamboo forests, constitute more than 2.21% (103 / 24 kinds of 4656), the distribution of the mosquito is more limited, and a smaller number. Aedes albopictus is widely distributed in Yunnan, especially in the southwestern province and the adjacent tropical tropical areas, is near the bamboo forest and hillside _set_tlements bamboo area of the main mosquito species. The nine counties investigation, the mosquito wild bamboo for the advantage or comparative advantage area mosquito species. Distribution of Aedes albopictus has a certain relationship with Habitat, where the number of mosquito habitats, are close to the village of bamboo trees. The habits of bloodthirsty mosquitoes wider, and many blood-sucking features. Foreign studies have shown that Aedes albopictus to infection, dissemination and encephalitis virus transmission by the egg [2-5]. The nature of Aedes albopictus from Yunnan to JE virus was isolated, and proved that the mosquito of Yunnan have a higher susceptibility to viral encephalitis, spread by the bite and can pass through the eggs encephalitis virus [6,7]. Aedes albopictus in the JE epidemic in synergy with Culex pipiens, is an important medium of JE virus, encephalitis virus in nature preservation and dissemination play an important role. No interference from the past, the assassination of Aedes, narrow wings and Aedes albopictus in Assam encephalitis virus isolated reports. The Aedes isolated from three kinds of JE virus, suggesting that they may participate in the spread of JE virus. Especially the assassination of interference and narrow wings Aedes albopictus, is not only the distribution of livestock in rural circles, but also the distribution of bamboo in the wild, a closer relationship with people and livestock, has important epidemiological significance.
