“…cruzii for blood feeding in the tree canopy [2, 8, 14]. Nevertheless, variations in the biting activity of this mosquito in the canopy and at ground level have been observed in different locations, and few studies have sought to understand the factors that lead to these variations [20, 22–24, 26, 54]. Investigating the vertical stratification of mosquitoes in forest areas in the northeast of the state of São Paulo, Forattini et al [20] observed differences in An.…”

Background The mosquito Anopheles ( Kerteszia ) cruzii is the main vector of human and simian malaria in the Atlantic Forest. This species is usually abundant in the forests where it occurs, preferring to live and feed on canopies, behaviour known as acrodendrophily. However, in several studies and locations this species has been observed in high density near the ground in the forest. In this study, it was hypothesized that factors associated with anthropogenic landscape changes may be responsible for the variation in abundance and acrodendrophily observed in An. cruzii . Methods The study was conducted in a conservation unit in the city of São Paulo, Brazil. Monthly entomological collections were performed from March 2015 to April 2017, and the resulting data were used with data from another study conducted in the same area between May 2009 and June 2010. Mosquitoes were collected from five sites using CDC and Shannon traps. Landscape composition and configuration metrics were measured, and generalized linear mixed-effect models were used to investigate the relationship between these metrics and variations in the abundance and acrodendrophily of An. cruzii . Results The model that showed the best fit for the relationship between landscape metrics and An. cruzii abundance suggests that an increase in the proportion of forest cover leads to an increase in the abundance of this mosquito, while the model that best explained variations in An. cruzii acrodendrophily suggests that an increase in total forest-edge length leads to greater activity by this species at ground level. Conclusion While the data indicate that changes in landscape due to human activities lead to a reduction in An. cruzii abundance, such changes may increase the contact rate between this species and humans living on the edges of forest fragments where An. cruzii is found. Future studies should, therefore, seek to elucidate the effect of these landscape changes on the dynamics of Plasmodium transmission in the Atlantic Forest, which according to some studies includes the participation of simian hosts.

“…aegypti by facilitating flight, giving insects the opportunity to reach more distant locations. Such events result in more available blood meal sources and increase the possibilities of expansion for oviposition due to the abundant presence of artificial habitats (Tauil , Santos‐Neto and Lozovei ), factors that contribute to make Ae. aegypti an effective agent in arbovirus transmission.…”

Aedes aegypti mosquitoes are highly adaptable to abiotic stimuli. To evaluate the influence of shading and pedestrian traffic on the preference of Ae. aegypti for oviposition microenvironments, 20 sites were sampled weekly using ovitraps within the perimeter of Universidade Federal do Espírito Santo, located in São Mateus, Espírito Santo, Brazil. A spatial and statistical analysis was performed in order to assess the relationship between shading time, pedestrian traffic, and the presence of biological forms of Ae. aegypti. A temporal analysis of temperature and precipitation influence on oviposition was also made. Between June, 2013 and June, 2014, 7,362 Ae. aegypti eggs were collected. Over a 12-month period, we made weekly collections of Ae. aegypti eggs from ovitraps. Pedestrian traffic and shading time influenced the number of positive ovitraps; precipitation and temperature were correlated with the number of positive ovitraps (p <0.05). We conclude that the influence of temperature and precipitation was not significant for the oviposition index, and the frequency of oviposition was directly proportional to the number of individuals moving close to the traps during periods of greater shading.

Ecosystem diversity of mosquitoes (Diptera: Culicidae) in a remnant of Atlantic Forest, Rio de Janeiro state, Brazil

Understanding mosquito biodiversity in the Atlantic Forest is important for assessing changes in the distribution of mosquito populations, which have been considered predominantly to be sylvatic. An observational study of Culicidae was conducted in a remnant of the Atlantic Forest in the Poço das Antas Biological Reserve, Silva Jardim municipality, Rio de Janeiro state, Brazil, to evaluate species diversity and the influence of climatic factors (temperature, relative humidity and rainfall) on species distribution. Two types of light trap were used: an automatic CDC trap baited with CO2 and a Shannon trap. Collections were also made using a manual suction tube. Overall, 15 700 Culicidae specimens were collected belonging to two subfamilies, 12 genera and 41 species. The most common species were Coquillettidia chrysonotum, Mansonia titillans and Coquillettidia venezuelensis. Principal component analyses indicated a major association between sampling site six and the species Anopheles albitarsis, Mansonia titilllans, Cq. chrysonotum and Cq. venezuelensis. Furthermore, diversity indices indicated that sampling sites 1, 6 and 4 displayed higher diversity and a more uniform species abundance. Culicidae abundance was positively correlated with temperature. Landscape units exhibited contrasting community compositions of mosquitoes at multiple scales, with the community composition more similar in sites with similar landscape parameters. The importance of constant entomological monitoring is underscored by the diversity of mosquito species in this reserve and their potential role in the transmission of pathogens, combined with intermittent flow of visitors to the area.
