World Mosquito Day
World Mosquito Day, observed annually on 20 August, is a commemoration of British doctor Sir Ronald Ross's discovery in 1897 that female anopheline mosquitoes transmit malaria between humans. Prior to the discovery of the transmitting organism, vector, there were few means for controlling the spread of the disease although the discovery of quinine in treatment had alleviated the problem of treatment. According to one survey, nearly half the world population was at significant risk from malaria in the 19th century with a 10% mortality among those infected. Ross had already conducted experiments with ''Culex'' (possibly ''C. fatigans'') fed on birds infected with bird malaria ''Protesoma relictum'' (now ''Plasmodium relictum'') in 1894 and noted that they developed in mosquito gut and had surmised that the same may happen in malaria. Ross had noted the day of the discovery made in Secunderabad (printed incorrectly as 1895, but definitely 1897 based on his postings). Patrik is celebr ...

Ronald Ross
Sir Ronald Ross (13 May 1857 – 16 September 1932) was a British medical doctor who received the Nobel Prize for Physiology or Medicine in 1902 for his work on the transmission of malaria, becoming the first British Nobel laureate, and the first born outside Europe. His discovery of the malarial parasite in the gastrointestinal tract of a mosquito in 1897 proved that malaria was transmitted by mosquitoes, and laid the foundation for the method of combating the disease. Ross was a polymath, writing a number of poems, published several novels, and composed songs. He was also an amateur artist and mathematician. He worked in the Indian Medical Service for 25 years. It was during his service that he made the groundbreaking medical discovery. After resigning from his service in India, he joined the faculty of Liverpool School of Tropical Medicine, and continued as Professor and Chairman of Tropical Medicine of the institute for 10 years. In 1926, he became Director-in-Chief of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anopheles
''Anopheles'' () is a genus of mosquito first described and named by J. W. Meigen in 1818. About 460 species are recognised; while over 100 can transmit human malaria, only 30–40 commonly transmit parasites of the genus ''Plasmodium'', which cause malaria in humans in endemic areas. '' Anopheles gambiae'' is one of the best known, because of its predominant role in the transmission of the most dangerous malaria parasite species (to humans) – '' Plasmodium falciparum''. The name comes from the Ancient Greek word 'useless', derived from , 'not', 'un-' and 'profit'. Mosquitoes in other genera (''Aedes'', ''Culex'', '' Culiseta'', '' Haemagogus'', and ''Ochlerotatus'') can also serve as vectors of disease agents, but not human malaria. Evolution The ancestors of ''Drosophila'' and the mosquitoes diverged . The culicine and ''Anopheles'' clades of mosquitoes diverged between and .

Mosquitoes
Mosquitoes (or mosquitos) are members of a group of almost 3,600 species of small flies within the family Culicidae (from the Latin ''culex'' meaning "gnat"). The word "mosquito" (formed by ''mosca'' and diminutive ''-ito'') is Spanish for "little fly". Mosquitoes have a slender segmented body, one pair of wings, one pair of halteres, three pairs of long hair-like legs, and elongated mouthparts. The mosquito life cycle consists of egg, larva, pupa, and adult stages. Eggs are laid on the water surface; they hatch into motile larvae that feed on aquatic algae and organic material. These larvae are important food sources for many freshwater animals, such as dragonfly nymphs, many fish, and some birds such as ducks. The adult females of most species have tube-like mouthparts (called a proboscis) that can pierce the skin of a host and feed on blood, which contains protein and iron needed to produce eggs. Thousands of mosquito species feed on the blood of various hosts — v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malaria
Malaria is a mosquito-borne infectious disease that affects humans and other animals. Malaria causes symptoms that typically include fever, tiredness, vomiting, and headaches. In severe cases, it can cause jaundice, seizures, coma, or death. Symptoms usually begin ten to fifteen days after being bitten by an infected mosquito. If not properly treated, people may have recurrences of the disease months later. In those who have recently survived an infection, reinfection usually causes milder symptoms. This partial resistance disappears over months to years if the person has no continuing exposure to malaria. Malaria is caused by single-celled microorganisms of the ''Plasmodium'' group. It is spread exclusively through bites of infected ''Anopheles'' mosquitoes. The mosquito bite introduces the parasites from the mosquito's saliva into a person's blood. The parasites travel to the liver where they mature and reproduce. Five species of ''Plasmodium'' can infect and be spread by h ...

Secunderabad
Secunderabad, also spelled as Sikandarabad (, ), is a twin cities, twin city of Hyderabad and one of the six zones of the Greater Hyderabad Municipal Corporation (GHMC) in the States and union territories of India, Indian state of Telangana. It is the headquarters of the South Central Railway zone. Named after the Mir Akbar Ali Khan Sikander Jah, Asaf Jah III, Nizam of Hyderabad, Nizam of the Asaf Jahi dynasty, Secunderabad was established in 1806 as a British cantonment. Although both the cities are together referred to as the twin cities, Hyderabad and Secunderabad have different histories and cultures, with Secunderabad having developed directly under British rule until 1948, and Hyderabad as the capital of the Nizams' Hyderabad State, princely state of Hyderabad. Geographically divided from Hyderabad by the Hussain Sagar lake, Secunderabad is no longer a separate municipal unit and has become part of Hyderabad's Greater Hyderabad Municipal Corporation. Both cities are collec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

August Observances
August is the eighth month of the year in the Julian and Gregorian calendars, and the fifth of seven months to have a length of 31 days. Its zodiac sign is Leo and was originally named '' Sextilis'' in Latin because it was the 6th month in the original ten-month Roman calendar under Romulus in 753 BC, with March being the first month of the year. About 700 BC, it became the eighth month when January and February were added to the year before March by King Numa Pompilius, who also gave it 29 days. Julius Caesar added two days when he created the Julian calendar in 46 BC (708 AUC), giving it its modern length of 31 days. In 8 BC, it was renamed in honor of Emperor Augustus. According to a Senatus consultum quoted by Macrobius, he chose this month because it was the time of several of his great triumphs, including the conquest of Egypt. Commonly repeated lore has it that August has 31 days because Augustus wanted his month to match the length of Julius Caesar's July, but ...

Insects In Culture
Human interactions with insects include both a wide variety of uses, whether practical such as for food, textiles, and dyestuffs, or symbolic, as in art, music, and literature, and negative interactions including serious damage to crops and extensive efforts to eliminate insect pests. Academically, the interaction of insects and society has been treated in part as cultural entomology, dealing mostly with "advanced" societies, and in part as ethnoentomology, dealing mostly with "primitive" societies, though the distinction is weak and not based on theory. Both academic disciplines explore the parallels, connections and influence of insects on human populations, and vice versa. They are rooted in anthropology and natural history, as well as entomology, the study of insects. Other cultural uses of insects, such as biomimicry, do not necessarily lie within these academic disciplines. More generally, people make a wide range of uses of insects, both practical and symbolic.
