| a polytene chromosome study of four populations of anopheles aquasalis from venezuela. | polytene chromosome studies were undertaken to elucidate taxonomic relationships among populations of anopheles aquasalis and a. emilianus in venezuela. four collection sites were chosen: two in sucre state (santa fe and guayana) where a. aquasalis (considered to be a. emilianus by gabaldón and escalante) is presumed to be the major regional vector of plasmodium vivax; and two in areas where no malaria transmission occurs (caño rico, aragua state, and puerto cabello, carabobo state). the chromos ... | 1992 | 1618392 |
| spatial and temporal distribution of anopheline larvae in two malarious areas in sucre state, venezuela. | the spatial and temporal distribution of anopheline larvae was studied in two coastal malarious areas of sucre, state, venezuela. seven habitat types were sampled in the village of guayana and eight species of anopheles were collected. anopheles aquasalis was the predominant species collected and was most abundant in the brackish marsh habitat (71 larvae per 100 samples). it was most abundant during the rainy season. at the second location, santa fé, six habitat types were sampled and four anoph ... | 1993 | 8107599 |
| adult abundance, biting behavior and parity of anopheles aquasalis, curry 1932 in two malarious areas of sucre state, venezuela. | the principal vector of malaria in eastern venezuela, anopheles aquasalis, is exophagic and exophilic. control using indoor insecticide house sprays has failed to lower the number of malaria cases. therefore, studies were initiated in two villages of the eastern coastal state of sucre to better understand this vector's biology and develop a more integrated control program. an. aquasalis was found to have a crepuscular biting behavior with a major peak at dusk and a minor peak at dawn. mosquitos ... | 1993 | 8107600 |
| anopheles aquasalis eggs from two venezuelan localities compared by scanning electron microscopy. | anopheles (nyssorhynchus) aquasalis, is the main coastal vector of malaria from northeastern venezuela to southeastern brazil. several authors have argued that an. aquasalis is a highly polymorphic species while others indicated that it is a complex of closely related species. this investigation compared the morphology of an. aquasalis eggs from sinamaica (zulia state) and yaguaraparo (sucre state), the west and east of venezuela, respectively. we were able to separate eggs from the two localiti ... | 1997 | 9361742 |
| [metabolic resistance to organophosphate insecticides in anopheles aquasalis curry 1932, libertador municipality, sucre state, venezuela]. | a study of insecticide resistance was undertaken at focal level in the localities catuaro, guayana, platanito and rio de agua, libertador county, sucre state, venezuela, a region with malaria transmission, where anopheles aquasalis is the main vector. | 2009 | 20440459 |
| [larval seasonality of the mosquito anopheles aquasalis (diptera: culicidae) and other insects associated to its habitat in sucre, venezuela]. | anopheles aquasalis curry is considered the main vector of human malaria in northern venezuela. a longitudinal study was carried out in the coastal areas of the paria peninsula, sucre state. the larval habitats of a. aquasalis were classified as: 1--brackish mangrove, and 2--freshwater herbaceous swamp. field surveys of mosquito larvae and aquatic insects were carried out in the same breeding sites over a one-year period, between january and december 1999. at each site, 30 samples of anopheles l ... | 2010 | 20527475 |
