| [host preference of culicidae (diptera) collected in central argentina]. | in order to study the host preference of female mosquitoes, samples were taken fortnightly in cordoba and cosquin (argentina), during october-april of two consecutive years. four different vertebrates were used in baited-can traps: frogs, chickens, rabbits and turtles. the genus culex accounted for 92.9% of the specimens collected. aedes for 7.0% and psorophora ciliata 0.02%. the highest proportion of females were collected in chicken traps (68.7%), followed by rabbit traps (29.9%), turtles (0.8 ... | 1995 | 8525319 |
| host range and specificity of an argentinean isolate of the aquatic fungus leptolegnia chapmanii (oomycetes: saprolegniales), a pathogen of mosquito larvae (diptera: culicidae). | an isolate from argentina of the fungal mosquito pathogen leptolegnia chapmanii (arsef 5499), was tested against 12 species of mosquito larvae and on species of non-target aquatic invertebrates and vertebrates. the mosquito species tested were aedes aegypti, anopheles sp., culex apicinus, cx. castroi, cx. dolosus, cx. pipiens, cx. renatoi, isostomyia paranensis, ochlerotatus albifasciatus, oc. crinifer, psorophora cyanescens, and p. ferox. mosquito larvae of 10 species were susceptible, with mor ... | 2004 | 15702269 |
| new records of mosquito species for central and cuyo regions in argentina. | the geographical distributions of aedes aegypti, culex apicinus, cx. educator, cx. interfor, cx. quinquefasciatus, mansonia humeralis, ma. indubitans, and psorophora albigenu/varipes are extended, including new records for 2 provinces. | 2009 | 19653506 |
| seasonal occurrence of immature mosquitoes in swimming pools in buenos aires, argentina. | the seasonal variation in the density of swimming pools and the occurrence of immature mosquitoes in these habitats were studied in the temperate city of buenos aires, argentina. the density of swimming pools was highest in the summer (6.0 pools/ha) when temporal pools predominated; it was lowest in the winter (0.9 pools/ha) when only permanent pools were recorded. the presence of immature stages of mosquitoes was mainly associated with the lack of use and maintenance of the pools in the fall se ... | 2010 | 20402356 |
| culicidae (diptera) selection of humans, chickens and rabbits in three different environments in the province of chaco, argentina. | studies were conducted to determine the selection of humans, chickens and rabbits by culicidae in three different environments in the province of chaco, argentina. mosquitoes were collected fortnightly using cylindrical metal traps containing animal bait (chickens and rabbits). the mosquitoes were collected between june 2001-may 2002. during the same period and with the same frequency, mosquitoes biting the human operators of the traps were collected during the first 15 min of exposure within di ... | 0 | 23903970 |
| silent circulation of st. louis encephalitis virus prior to an encephalitis outbreak in cordoba, argentina (2005). | st. louis encephalitis virus is a complex zoonoses. in 2005, 47 laboratory-confirmed and probable clinical cases of slev infection were reported in córdoba, argentina. although the causes of 2005 outbreak remain unknown, they might be related not only to virological factors, but also to ecological and environmental conditions. we hypothesized that one of the factors for sle reemergence in córdoba, argentina, was the introduction of a new slev genotype (slev genotype iii), with no previous activi ... | 2012 | 22303490 |
| characterisation of culex quinquefasciatus (diptera: culicidae) larval habitats at ground level and temporal fluctuations of larval abundance in córdoba, argentina. | the aims of this study were to characterise the ground-level larval habitats of the mosquito culex quinquefasciatus, to determine the relationships between habitat characteristics and larval abundance and to examine seasonal larval-stage variations in córdoba city. every two weeks for two years, 15 larval habitats (natural and artificial water bodies, including shallow wells, drains, retention ponds, canals and ditches) were visited and sampled for larval mosquitoes. data regarding the water dep ... | 0 | 24037200 |
| effect of different thermal conditions on the pre-imaginal biology of culex apicinus (philippi, 1865) (diptera: culicidae). | the time of development and survival of the pre-imaginal period and the adult body size of culex apicinus were analyzed in individuals reared from the 1st instar larva to adult emergence under laboratory and field conditions. in the laboratory, insects were exposed to three constant temperatures (15, 20, and 25 degrees c) and a photoperiod of 14:10 (l:d). in the field, temperature and photoperiod were not manipulated; during the study period water temperature ranged between 15.5 and 24.2 degrees ... | 2007 | 17639632 |
| culex species (diptera: culicidae) from central argentina: identification by electrophoretic zymograms and genetic relationships. | starch gel electrophoretic zymograms were used for the taxonomic separation of mosquitoes of the genus culex, possible vectors of encephalitis in argentina. catalase, hexokinase, malic enzyme, isocitrate and malate dehydrogenases, and leucine aminopeptidase were species markers that allowed the clear identification of individual culex apicinus philippi, cx. bidens dyar, cx. brethesi dyar, cx. declarator dyar and knab, cx. dolosus arribalzaga, cx. maxi dyar, cx. quinquefasciatus say, cx. saltanen ... | 1990 | 2231615 |
