The Culicidae family is represented by approximately 3,610 species, among which many are involved in transmission of pathogens and parasites, thus presenting great medical-veterinary importance. In Brazil, the state of Pernambuco is considered an endemic area for many diseases vectored by mosquitoes, such as human and canine filariasis, caused by Wuchereria bancrofti and Dirofilaria immitis, respectively. The aim of this study was to evaluate the occurrence of immature forms of culicids, over an one-year period, in a specific area of northeastern region of Brazil. Culicids larvae were collected from traps located on the ground and in treetops, between october 2012 and september 2013. Ten different species of culicids were identified. The greatest number of larvae were collected in september 2013 and the lowest number in december 2012. Stegomyia (Stegomyia) albopicta (46.45%; 5,908/12,718), Culex (Culex) maxi (35.56%; 4,523/12,718) and Limatus durhamii (12.58%; 1,600/12,718) were the most frequent species. The human and animal populations living in the study area are exposed to culicids and transmission agents throughout the year, especially after the rains. Therefore, control and prevention measures against culicids must be adopted in the study area.Keywords: Mosquitoes, seasonal, abundance, vectors, Culicidae. ResumoA família Culicidae é representada por aproximadamente 3.610 espécies, dentre as quais muitas estão envolvidas na transmissão de patógenos e parasitos, apresentando assim grande importância médico-veterinária. No Brasil, o Estado de Pernambuco é considerado área endêmica para diversas doenças transmitidas por mosquitos como, por exemplo, as filarioses humana e canina causadas pela Wuchereria bancrofti e Dirofilaria immitis, respectivamente. O objetivo deste estudo foi avaliar a ocorrência de formas imaturas de culicídeos durante um ano em uma área do Nordeste do Brasil. Larvas de culicídeos foram coletadas em armadilhas localizadas no solo e copa de árvores, no período de outubro de 2012 a setembro de 2013. Dez diferentes espécies de culicídeos foram identificadas, sendo o maior número de larvas coletadas em setembro de 2013 e o menor número em dezembro de 2012. Stegomyia (Stegomyia) albopicta (46,45%; 5.908/12.718), Culex (Culex) maxi (35,56%; 4.523/12.718) e Limatus durhamii (12,58%; 1.600/12.718) foram as espécies mais frequentes. A população humana e animal residente na área de estudo é exposta aos culicídeos e aos agentes por eles veiculados durante todo o ano, sobretudo após o período de chuvas. Portanto, medidas de controle e prevenção dos culicídeos devem ser adotadas na área estudada.

Diversity of mosquitoes (Diptera: Culicidae) collected in different types of larvitraps in an Amazon rural settlement

Anthropogenic environments provide favorable conditions for some species, which is especially true of mosquitoes that present eclecticism at the moment of choice for the site of oviposition. In the present study, the diversity of mosquitoes was assessed by providing plastic containers, bamboo internodes, and tires in a forest, the forest edge, and peridomicile environments in a rural settlement area. Eighteen sampling points were chosen, delimited by a buffer of 200 m, placed in three environments: forest, forest edge, and peridomicile. In each environment, larvitraps were installed, separated by a minimum distance of 7 m and 1 m from the ground. A total of 10,131 immature mosquitoes of 20 species were collected. The most abundant species was Culex urichii (29.5%), followed by Trichoprosopon digitatum (27.1%), and Cx. (Melanoconion) spp. (10.4%). There was a difference in the composition of immature mosquito populations between larvitraps (p < 0.0005), and the plastic container hosted a greater diversity of species, whereas tires presented a greater abundance of individuals. The forest, forest edge, and peridomicile environments were also different with regard to diversity of immature mosquito populations (p < 0.0010). The forest edge was the environment with the greatest diversity of species, followed by the peridomicile and forest environments. In the forest and peridomicile, plastic container larvitraps had the greatest diversity, whereas the forest edge tire presented the largest number of individuals. Further, tire larvitraps collected the largest number of individuals in all environments. Ten species associated with the bamboo internode and tire were identified. The preference of species for artificial larvitraps, such as the plastic container and tire, even in wild environments was noted. These artificial objects may represent a risk factor for the population living in this region, as all vector species found in the study were present in plastic containers and tires.

Anthropogenic environments provide favorable conditions for some species, which are especially suitable for mosquitoes that present eclecticism at the moment of choice for the site of oviposition. The present study, the diversity of mosquitoes in plastic container, bamboo internode, and tire placed in forest, the forest edge, and peridomicile environments in a rural settlement area was assessed. Eighteen sampling points were chosen, delimited by a buffer 200 m, placed in environments: forest, forest edge, and peridomicile. In each environment, larvitraps were installed, separated by a minimum distance of 7 m and 1 m from the ground. A total of 10,131 immature mosquitoes of 20 species were collected. The most abundant species was Culex urichii (29.5%), followed by Trichoprosopom digitatum (27.1%), and Cx. (Melanoconion) sp. (10,4%). There was a difference in the composition of immature mosquito populations between larvitraps (p<0.0005), and the plastic container hosted a greater diversity of species, whereas tires presented a greater abundance of individuals. The forest, forest edge, and peridomicile environments were also significantly different with regard to diversity of immature mosquito populations (p<0.0010). The forest edge was the environment with the greatest diversity of species, followed by the peridomicile and forest environments. In the forest and peridomicile, plastic container larvitraps had the greatest diversity, whereas the forest edge tire presented the largest number of individuals. Further, tire larvitraps collected the largest number of individuals in all environments. We identified 10 species associated with the bamboo internode and tire. We also observed the preference of species for artificial larvitraps, such as the plastic container and tire, even in wild environments. These artificial objects may represent a risk factor for the population living in this region, as all vector species found in the study were present in plastic containers and tires.
