| variability among tunisian populations of culex pipiens: genetic structure and susceptibility to a filarial parasite, brugia pahangi. | culex pipiens pipiens is a common mosquito found in north africa and is the primary vector of bancroftian filariasis in egypt. experimental infections with c. p. pipiens have demonstrated that this species supports brugia pahangi development (parasitic yield 6.3%). in addition, the genetic variation among c. p. pipiens populations from ben arrous (in the suburb of tunis) estimated from isoenzyme polymorphism of five neutral genes (pgm, gpi, hk1, got-1, and got-2) was slight (fst = +0.083). c. p. ... | 1998 | 9493214 |
| [sensitivity of mosquito larvae to insecticides in the region of tunis in 1984 and 1988]. | three pesticides were tested in the laboratory (chlorpirifos, temephos and fenthion) against culex pipiens larvae. the study was conducted in the area of tunis during the years 1984 to 1988. after several years of treatment with there organophosphoric compounds, the resistance rates reached by the treated larval population never exceeded 15, which is much lower than the rates observed in other countries. | 1989 | 2482709 |
| [a winter seasonal biotope of culex pipiens autogenicus]. | the authors describe an epigeal winter seasonal biotope of "culex pipiens autogenicus. the biotope consists of the irrigation system of the large bervedere park of tunis city. during the cold and rainy season the irrigation system is abandoned. many water pools are formed in it in which c. pipiens and culiseta longiareolata multiply. in summer the operation of the irrigation system brings about the disparition of the nests of larvae. breeding performed from larvae collected in nature pointed out ... | 1975 | 1243883 |
