Abstract: bromeliad-associated mosquitoes (diptera: culicidae) in atlantic forest in florianópolis, santa catarina, southern brazil, were studied, examining plants of vriesea philippocoburgi wawra and aechmea lindenii (e. morren) baker var. lindenii at secondary atlantic rain forest, and a. lindenii and vriesea friburgensis mez var. paludosa (l. b. smith) at "restinga" per month, during 12 months. no immature forms of mosquitoes were collected from a. lindenii in the secondary forest. collections obtained 368 immature mosquitoes, none of them from a. lindenii from rain forest. culex (microculex) spp. constituted 79.8% of the total, wyeomyia (phoniomyia) spp. 17.93%, and anopheles (kerteszia) cruzii (dyar & knab, 1908) only 1.36%. the study shows the great predominance of species of medical importance not yet proved, and the small number of immature stages of anopheline mosquitoes. the rainfall, but not the mean temperatures, significantly influenced the quantity of mosquitoes from v. philippocoburgi. significant differences between the quantities of immature forms of all the bromeliad species were found, and the shape of the plants could be important to the abundance of mosquitoes. all six species of cx. (microculex) found are recorded for the first time in the state of santa catarina, and all six species of wyeomyia (phoniomyia) are recorded for the first time in bromeliads in this state.
Immature mosquitoes (Diptera: Culicidae) on the bromeliad Nidularium innocentii in ombrophilous dense forest of Santa Catarina Island, Florianópolis, Santa Catarina State, southern Brazil

Abstract: Immature forms of mosquitoes (Diptera: Culicidae) were collected from bromeliads Nidularium innocentii var. paxianum in dense ombrophilous forest of Santa Catarina Island, state of Santa Catarina. Two hundred and eleven mosquitoes were collected; 37.44% Culex (Microculex) albipes, 19.91% Cx. (Mic.) davisi, 0.95% Anopheles (Kerteszia) cruzii and 0.47% Wyeomyia (Phoniomyia) tripartita. Correlation between the quantities of collected mosquitoes and mean temperatures was significantly positive, but that between the quantities and the rainfall was not. The quantity of anophelines was much smaller than that reported by other workers in the same region. Even considering the small quantity of anophelines collected, the great density of this bromeliad in the area indicates the need for of attention to it as a breeding ground for these mosquitoes.

Abstract: two thousand and sixty one specimens distributed in 36 species of mosquitoes were collected between august 2007 and may 2008 at the environmental conservation unit desterro (located in santa catarina state, brazil). the five most abundant species were: runchomyia reversa (29.74%), ochlerotatus scapularis (14.80%), wyeomyia pallidoventer (9.51%), anopheles cruzii (8.30%) and sabethes purpureus (7.03%). ten species of culicidae are firstly reported to the santa catarina state, and of these, six belong to the genus wyeomyia.
Aplica??o de marcadores microssatélites para o estudo de Culicidae (Diptera): revis?o com especial referência a Haemagogus

Boletín de Malariología y Salud Ambiental , 2010,
Abstract: microsatellite molecular markers are characterized by neutrality, high polymorphism and wide distribution with high abundance in the genome of eukaryotes. its use in studies related to species of mosquito vectors is ideal for genetic and physical mapping, for the identification and discrimination of genotypes and genetic studies of populations. this review summarizes and provides information on studies involving mosquitoes by using microsatellite markers and suggests avenues of research to better understand the biology and dynamics of transmission of yellow fever virus by haemagogus mosquitoes.

Revista Brasileira de Entomologia , 2009, DOI: 10.1590/S0085-56262009000400016
Abstract: the development time of the immature forms of sabethes aurescens lutz, 1905, from perforated bamboo in the southern brazil rain forest was studied under laboratory conditions. mean development periods were 5±2.23, 10±5.20, 14±8.26, 36±13.90 and 9±2.43 days, respectively, for the four larval instars and pupae. the 4th instar of females was longer than that of males. implications of the long development time of the immature forms of sa. aurescens are discussed.

Abstract: the efficiency of an alternative method of collection (by suction of water) for the study of culicidae and chironomidae (diptera), scirtidae (coleoptera) and coenagrionidae (odonata) in bromeliads with different foliar architecture in a restinga at florianópolis, sc, brazil, was studied. the alternative method was less efficient to collect culicidae and chironomidae (wilcoxon test p < 0.05) and was more efficient to scirtidae and coenagrionidae (wilcoxon test p > 0.05) from aechmea lindenii. this method was less efficient to collect insects of all groups from vriesea friburgensis (wilcoxon test p < 0.05). the alternative method was efficient to estimate the diversity of these insects in both species of bromeliads. the higher mobility of immature forms of beetles and dragonflies, and the availability of only one tank in aechea lindenii, contrasting to several tanks in vriesea friburgensis that help the suction of these immature, probably influenced the results, which indicated that the suction method should not replace the dismantling in the study of culicidae and chironomidae. this method can be useful to get immature forms of scirtidae and coenagrionidae in one-tank bromeliads.

Abstract: crepuscular activity of culicids (diptera, culicidae) in the peridomicile and in the remaining riparian forest in tibagi river, state of paraná, brazil. human-attracted mosquitoes were collected for one hour, around sunset time (half hour before and half after), from april to december 2006, in two environments (riparian forest and near houses), in tibagi river basin, palmeira municipality, state of paraná. seven-hundred forty-nine mosquitoes, belonging to 13 species, were collected. psorophora champerico dyar & knab, 1906 (42.86%) and psorophora discrucians (walker, 1856) (40.59%) were the most frequent species. no significant differences between quantities of ps. champerico (t = -0.792; d.f. = 16; p = 0.43) and ps. discrucians (t = 0.689; d.f. = 16; p = 0.49) obtained in riparian forest and near houses were observed, indicating similar conditions for crepuscular activity of these species in both environments. psorophora champerico and ps. discrucians responded (haematophagic activity) to environmental stimuli associated with the twilight hours differently in distinct habitats studied. the former species is registered for the first time in the atlantic forest biome.
