Abstract
Arboviruses are arthropod-dependent viruses to complete their zoonotic cycle. Among the transmitting arthropods, culicids stand out, which participate in the cycle of several arboviruses that can affect humans. The present study aimed to identify species of culicidae and to point out the risk of circulation, emergency, or reemergence of pathogenic arboviruses to humans in the region of the Jequitibá headquarters of the Parque Estadual dos Três Picos (PETP), in Cachoeiras de Macacu, state of Rio de Janeiro, Brazil. Sampling was carried out at five Sample Points (SP) demarcated on trails from the headquarters, with CDC light traps, HP model with dry ice attached to the side, for 48 hours of activity each month. Additionally, active catches were made with a castro catcher in the period of one hour per day in the field, from six to eleven o'clock in the morning, in each PM. After the captures, thematic map was assembled using the ArcGIS 10 software and performing a multidimensional scaling (MDS). A total of 1151 specimens were captured and the presence of culicids already incriminated as vectors of arboviruses circulating in the region was observed: Aedes fluviatilis Lutz, 1904 (71 specimens); Aedes scapularis Rondani, 1848 (55 specimens); Haemagogus leococelaenus Dyar and Shannon, 1924 (29 specimens). In addition to the subgenus Culex (culex) spp. (163 specimens). In this sense, we highlight the importance of strengthening the actions of continuous entomological surveillance of the emergence and re-emergence of new arboviruses in ecotourism visitation parks.
Highlights
Mosquitoes have a cosmopolitan distribution and are vectors of human and animal pathogens of global occurrence
In addition to the subgenus Culex spp. (163 specimens); Two thematic maps were made, one for the rainy season (Fig 2) and another for the dry period (Fig 3) where it is possible to visualize the distribution of species of medical and veterinary interest in each MS, and these were correlated with the arboviruses of according to the literature
Abreu et al (2019) confirmed the incrimination of the species Haemagogus janthinomys and Haemagogus leucocelaenus in the recent cases of yellow fever that occurred in the reemergence of the disease in the Atlantic Forest regions in southeastern Brazil
Summary
Mosquitoes have a cosmopolitan distribution and are vectors of human and animal pathogens of global occurrence. Composition of the culicidae community of the três picos state park, Rio de Janeiro, Brazil. There may be human insertion in this dynamic due to exposure caused by anthropic changes in the environment, the frequency in protected areas for ecotourism activities or other profit-making activities, and even the presence of homes, providing contact with females of infected wild mosquitoes. In this contact with the wild cycles, man can become infected, becoming a source of infection for urban mosquitoes, favoring the emergence of urban cycles of these diseases [2]. To assess the possibility of circulation of some of these arboviruses within the limits of the PETP headquarters, in addition to alerting to the possible introductions or reemergence of any new arboviruses due to the presence of their possible incriminated vector
