“…Studies on entomopathogenic fungi have shown their promise as biological control agents of mosquito vectors of tropical diseases (Messias 1989).There are many examples worldwide related to the interactions of fungi and Culicidae larvae (e.g. Agarwala et al 1999, Lucarotti & Shoulkamy 2000, Scholte et al 2004, Pereira et al 2005. However, the present paper is the fi rst study of Hyphomycetes fungi associated with Culicidae larvae in the Brazilian Amazon region.…”

“…Fungi can occasionally attack insects or develop symbiotic relationships (3). Many interactions between fungi and mosquitoes have been reported worldwide (4)(5)(6)(7)(8)(9)(10). Other interactions between bees and fungi have been documented, as well (11)(12)(13).…”

Objective: Fungi are the main source of aflatoxin contamination in nature. The present study aimed to assess the role of the cosmopolitan mosquito species, Culex pipiens, in the circulation and dissemination of pathogenic fungi in nature, and to evaluate its capability to harbor these fungi. Materials and Methods: Fungi were isolated and identified from both, the external surface and the internal organs of the developmental stages and from the breeding environment of Cx. pipiens. Results: A total of 35 fungal isolates were isolated from both, the internal organs and the external surface of the developmental stages and from the breeding environment of Cx. pipiens. These isolates were identified as eleven Penicillium notatum isolates, eleven Aspergillus flavus isolates, six Rhizopus stolonifer isolates, four Candida albicans isolates, two Fusarium solani isolates, and one Aspergillus niger isolate. Antagonistic activity showed that the P. notatum growth inhibited the growth of the bacteria, Staphylococcus aureus. Conclusions: This study revealed that the different developmental stages of Cx. pipiens mosquito were capable of harboring many fungal species. Subsequently, this mosquito will be incriminated in the mechanical dissemination, circulation, and transmission of these fungi in nature, during its life cycle.

“…The high abundance of Cx. urichii had not yet been recorded in previous studies of mosquito ecology in the Brazilian Amazon [45,46], however, at low frequencies, this species can be observed in natural and artificial breeding sites in forest areas of the Manaus municipality, Amazonas [47,48]. Trichoprosopon digitatum , followed by Cx .…”

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.
