“…Based on this, a second hypothesis is that the reduction in humidity due to the edge effect in more fragmented areas may favour increased An. cruzii activity in the lower stratum, which agrees with the observations of Veloso et al [64] and Guimarães et al [65] regarding the effect of air humidity on the flight activity of Kerteszia mosquitoes.…”

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.

“…durhami, are associated with areas inhabited by humans because eggs and larvae of this species are frequently found in artificial breeding sites such as plastic bottles (Guimarães and Arlé 1984). Our study corroborates the findings by both Guimarães and Victório (1986) and Guimaraes and Arlé (1984) who report Limatus species present in sylvatic environments and human modified environments, respectively.…”

There have been several important outbreaks of mosquito‐borne diseases in the Neotropics in recent years, particularly in Brazil. Some taxa are also considered to be indicators of environmental health. Despite the importance of understanding insect abundance and distribution to the understanding of disease dynamics and design strategies to manage them, very little is known about their ecology in many tropical regions. We studied the abundance and diversity of mosquitoes and sand flies in the Bahia State of Brazil, a point of origin for arbovirus outbreaks, including Zika and Chikungunya fever. During 2009‐2014, 51 mosquito taxa were identified, belonging to three dipteran families, Ceratopogonidae, Culicidae, and Psychodidae. The family Culicidae, including the Sabethini tribe, were the most abundant (81.5%) and most taxa‐rich (n=45). While season (winter and summer) was a strong factor determinant of the occurrence of the most abundant taxa, the stratification level in the forest (ground or tree level) had a strong effect and the dominant taxa at ground level were completely different from the dominant species collected at tree level. We suggest that sites with a mix of forest and agroforestry systems support the highest biodiversity of hematophagous insects as compared to highly disturbed landscapes.

“…Ae. scapularis, nos estudos de GUIMARÃES & VICTORIO (1986), apresentou o segundo tipo de distribuição, embora também tenha sido capturada em elevados números em diferentes horas do dia. De modo geral, esta espécie apresenta aumento de sua atividade hematofágica no início do crepúsculo vespertino.…”

scapularis (Rondani, 1948) was studied in a small area of the Atlantic Forest, Serra do Marumbi, Morretes, Paraná, Brazil. Adults were captured with Shannon light traps for 48 nights, representing 12 nights for seven time intervals. Traps were operated from dusk to dawn. The influences on flight activity of the lunar phase, ambient temperature, relative humidity, and rainfall were analyzed. Ae. scapularis had a flight behaviour different in each of the four lunar phases. In relation to flight period, the species showed higher activity during the first three lunar intervals. Among the climatic variables, temperature and relative humidity positively influenced flight activity during the night.
