Motta, Monique Albuquerque;Louren?o-de-Oliveira, Ricardo;
Memórias do Instituto Oswaldo Cruz , 1995, DOI: 10.1590/S0074-02761995000300012
Abstract: wyeomyia (dendromyia) luteoventralis is redescribed from females, males, larvae and pupae collected at the type locality, in brazil, and compared to the closely related species. at least six species - wy. luteoventralis, wy. ypsipola, wy. testei, wy. trifurcata, wy. complosa and wy. jocosa - appparently, belong to a monophyletic group, the subgenus dendromyia. all other species previously included in dendromyia are hereby excluded from this subgenus and retained in genus wyeomyia without subgeneric placement.
Immature mosquitoes (Diptera: Culicidae) on the bromeliad Nidularium innocentii in ombrophilous dense forest of Santa Catarina Island, Florianópolis, Santa Catarina State, southern Brazil

Biotemas , 2007,
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: 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.
Wyeomyia exallos, a new species of sylvatic mosquito (Diptera: Culicidae) from Brazil
Rocha, Glauber Pereira;Louren?o-de-Oliveira, Ricardo;Motta, Monique de Albuquerque;
Memórias do Instituto Oswaldo Cruz , 2012, DOI: 10.1590/S0074-02762012000700015
Abstract: wyeomyia exallos, a new mosquito species from atlantic forest of southeastern brazil, is described based on morphological characters of the adult female, male, male genitalia, pupa and fourth-instar larva. the morphological characters of wy. exallos sp. nov. are compared with those of different subgenera of wyeomyia as well as of species without subgeneric position. it is proposed that the new species should be placed in genus wyeomyia theobald without subgeneric assignment.

Motta, Monique Albuquerque;Louren?o-de-Oliveira, Ricardo;
Memórias do Instituto Oswaldo Cruz , 2000, DOI: 10.1590/S0074-02762000000500011
Abstract: a morphological study of larval, pupal and adult life stages (including genitalia characters) was performed in order to evaluate the classification of the subgenus dendromyia, genus wyeomyia theobald. six species are included: wy. ypsipola dyar, wy. jocosa (dyar & knab), wy. testei senevet & abonnenc, wy. complosa (dyar), wy. luteoventralis theobald and wy. trifurcata clastrier, the first four of which are redescribed. the descriptions include illustrations of the male and female genitalia, fourth-instar larva and pupa. the result firmly supports dendromyia as a monophyletic group, with well defined characters. keys for the identification of all life stages of species included in dendromyia are provided.

Motta, Monique Albuquerque;Louren?o-de-Oliveira, Ricardo;Monteiro, Fernando Araujo;Barros, Luciana Ramos;
Memórias do Instituto Oswaldo Cruz , 1998, DOI: 10.1590/S0074-02761998000200010
Abstract: an eletrophoretic analysis of three species of the subgenus dendromyia (wyeomyia luteoventralis, wy. ypsipola and wy. testei) and three species belonging to different groups in the genus wyeomyia (wy. negrensis, wy. mystes and wy.confusa) was performed. eight enzyme loci were analyzed. high values of genetic identity were detected among the species of the subgenus dendromyia: wy. luteoventralis, wy. ypsipola and wy. testei (mean value 0.63). on the other hand low values of genetic identity were observed among wy. negrensis, wy. mystes and wy. confusa (mean value 0.23), suggesting that they belong, at least, to distinct subgenera within the genus wyeomyia. the upgma phenogram revealed the grouping of the dendromyia species, while the others clustered at lower identity levels.

Torreias, Sharlene Roberta da Silva;Ferreira-Keppler, Ruth Leila;Godoy, Bruno Spacek;Hamada, Neusa;
Revista Brasileira de Entomologia , 2010, DOI: 10.1590/S0085-56262010000400013
Abstract: mosquitoes in the family culicidae develop their immature forms in different environments depending on various circumstances. this study represents the first contribution to the ecological knowledge of culicids living in the bromeliad g. brasiliensis. the objectives of the study were to compare the culicidae fauna of bromeliads in two seasonal periods, analyzing their abundance, richness and the influence of ph, conductivity and water volume, on the populations. sampling was done at reserva adolpho ducke, manaus, amazonas, brazil between 2003 and 2005. six samplings were done in the rainy season and six in the dry season. on each sampling day, six terrestrial and six epiphytic bromeliads, totaling 144 sampling units, were retrieved. a total of 444 immature mosquitoes were collected, distributed in the following species: culex (microculex) stonei lane & whitman, culex (microculex) chryselatus dyar & knab, culex (microculex) sp., wyeomyia (hystatomyia) autocratica dyar & knab and wyeomyia (hystatomyia) splendida bonne-wepster & bonne. the relationship between abundance of culicidae and sampling period was not significant, although abundance was higher in the dry period. there were significant correlations between water volume and the abundance (p = 0.003) and richness (p = 0.001) of culicids. the ph was positively related to the occurrence of the species wy. autocratica (p= 0.010) and wy. splendida (p= 0.006), demonstrating the influence of this factor in the structuring of bromeliad-inhabiting communities.
