| characterization of the culex pipiens complex (diptera: culicidae) in madagascar. | morphological analysis of phallosome and multilocus electrophoresis were used to characterize populations of the culex pipiens l. complex from madagascar. samples phenotypically and genetically corresponding to cx. p. quinquefasciatus say were found on the east and west coasts, whereas, on the high plateau, 1 sample was composed mostly of phenotypical cx. p. pipiens l., genetically introgressed with quinquefasciatus at some loci (hbdh, aat-2, and hk-1). a hybrid zone between the 2 taxa was detec ... | 1995 | 8551499 |
| cytoplasmic incompatibility as a means of controlling culex pipiens quinquefasciatus mosquito in the islands of the south-western indian ocean. | the use of the bacterium wolbachia is an attractive alternative method to control vector populations. in mosquitoes, as in members of the culex pipiens complex, wolbachia induces a form of embryonic lethality called cytoplasmic incompatibility, a sperm-egg incompatibility occurring when infected males mate either with uninfected females or with females infected with incompatible wolbachia strain(s). here we explore the feasibility of the incompatible insect technique (iit), a species-specific co ... | 2011 | 22206033 |

| the significance of the culex pipiens fatigans wiedemann problem in ceylon. | bancroftian filariasis became a problem in ceylon after the second world war. the only vector is culex pipiens fatigans, which is widely distributed throughout the country and is prevalent throughout the year. it is a domestic mosquito found resting mainly on hangings and household articles. its biting hours are from dusk to dawn, with peaks around midnight and in the early hours of the morning. so far this mosquito has not been incriminated as either the natural or the laboratory vector of anim ... | 1967 | 5300061 |
| a study of the age-composition of natural populations of culex pipiens fatigans wiedemann in relation to the transmission of filariasis due to wuchereria bancrofti (cobbold) in ceylon. | filariasis due to wuchereria bancrofti is becoming an increasingly important problem in many countries of southern and south-eastern asia. from 1962 to 1964, a study was made of the vector of this disease, culex pipiens fatigans, in two districts of colombo, ceylon, one with vector control by larviciding and one without. catches were made of the house-resting, biting and ovipositing populations, and the stages of ovarian development, parity and infection were determined by examination of the ext ... | 1967 | 5300045 |
| filarial diseases in ceylon: a geographic and historical analysis. | medical records concerning filarial diseases in ceylon date from the account of davy[1], though there are hints as to the more obvious manifestations in the old chronicles of the country, too. a first survey was conducted in 1912/1913 concentrating on urban areas, followed by a second survey in the 1930s with emphasis on the rural parts. the results displayed a remarkable distribution pattern: wuchereria bancrofti, the so-called "urban type", concentrated in galle and matara towns, whereas brugi ... | 1983 | 6152421 |

| [ecology of culex pipiens fatigans larvae in an area of high endemicity of bancroftian filariasis (author's transl)]. | culex pipiens fatigans in the main vector of bancroftian filariasis in the mayotte island (comores) where it imposes an important health problem. the breeding-sites of c. p. fatigans are either man-made (latrines, cesspools, various containers), or natural (polluted water of estuaries of some rivers). the man-made breeding-sites are not similarly distributed in the different localities of the island. their distribution varies according to the customs of the inhabitants, size and site of the comm ... | 1975 | 1096384 |
| entomological aspects of filariasis control in sri lanka. | historical events and suitable environmental conditions in the southwestern coastal areas of sri lanka have led to the establishment of a zone of endemic filariasis caused by wuchereria bancrofti and transmitted by culex pipiens fatigans. the previous brugia malayi foci, scattered over widely dispersed areas of the island, were apparently completely eliminated as a result of control of the mansonia vectors by the destruction of the larval host plants in their swamp habitats. control measures by ... | 1974 | 4619057 |
| insecticide resistance in culex pipiens quinquefasciatus and aedes albopictus mosquitoes from la réunion island. | resistance to insecticides was monitored on culex pipiens quinquefasciatus mosquitoes collected in twelve localities of la réunion, a geographically isolated island of the indian ocean. this mosquito is of medical concern in the region as a known vector for filariasis and a potential vector for west nile and rift valley fever viruses. our bioassays indicated the presence of resistance to all tested insecticides, i.e. organochlorides, organophosphates and pyrethroids. a molecular investigation re ... | 2010 | 20188834 |

| loss of filarial larvae in a natural mosquito population. | analysis of log normal parasite densities of wuchereria bancrofti in the mosquito culex pipiens fatigans collected in the suburbs of colombo, sri lanka, has shown a decreasing parasite load with age of infection. the median density of microfilarial intake in the natural population was 10.3, but this had decreased to 2.6 by the infective stage. of the total microfilariae ingested, 51.9% were found in the thorax 12--17 hours after infection of the mosquitoes in the laboratory. further decrease in ... | 1978 | 367299 |
