Abstract
Mosquitoes of the genus Sabethes are exclusively sylvatic species occurring in Central and South Americas, where they play a role in the transmission of arbovirus. Sabethes identicus, a common bamboo-breeder species, has been found naturally infected with yellow fever virus. Our study aimed to describe biological and behavioral features of Sa. identicus in the laboratory, as well as establish and standardize an isolated colony for experimental assays. We tested different larval densities and evaluated larval and pupal development time, oviposition behavior, egg production, and longevity. We also shot and video-documented bionomics and behavioral aspects of the mosquitoes in the field and laboratory. A colony with more than 30 generations was achieved. Embryogenesis of Sa. identicus is completed in about three days with a 79% hatch rate, while larval and pupal development takes approximately 15-17 and nine days, respectively. The mosquito's entire life cycle lasts approximately 30 days. Adult females could survive 71 days, and each individual laid an average of 88 eggs over their lifetime; 50% of females and males survived 37 and 24 days, respectively. Hematophagy peaks as early as the first week of emergence. The net content of a bamboo internode influenced the choice for oviposition, with the average number of eggs laid in those containing rearing water with larval and pupal exuviae being significantly higher than when they had only dechlorinated water or water with yeast. We documented for the first time an ecological association of weevils and Sa. identicus, where the oviposition of the latter depends on the weevil creating a hole in the bamboo wall for egg-laying purposes. Video recordings revealed for the first time the peculiar movements of gravid females during egg-throwing into tiny bamboo holes, as well as the laborious escape of newly emerged adults from the bamboo cavity, and mating behavior.

Abstract
Mosquitoes are vectors of many pathogens, including viruses, protozoans, and helminths, spreading these pathogens to humans as well as to wild and domestic animals. As the identification of species and the biological characterization of mosquito vectors are cornerstones for understanding patterns of disease transmission, and the design of control strategies, we conducted a literature review on the current use of noninvasive and nondestructive techniques for pathogen detection in mosquitoes, highlighting the importance of their taxonomic status and systematics, and some gaps in the knowledge of their vectorial capacity. Here, we summarized the alternative techniques for pathogen detection in mosquitoes based on both laboratory and field studies. Parasite infection and dissemination by mosquitoes can also be obtained via analyses of saliva- and excreta-based techniques or of the whole mosquito body, using a near-infrared spectrometry (NIRS) approach. Further research should be encouraged to seek strategies for detecting target pathogens while preserving mosquito morphology, especially in biodiversity hotspot regions, thus enabling the discovery of cryptic or new species, and the determination of more accurate taxonomic, parasitological, and epidemiological patterns.

Abstract
In Brazil, a yellow fever (YF) outbreak was reported in areas considered YF-free for decades. The low vaccination coverage and the increasing forest fragmentation, with the wide distribution of vector mosquitoes, have been related to yellow fever virus (YFV) transmission beyond endemic areas since 2016. Aiming to elucidate the molecular and phylogenetic aspects of YFV spread on a local scale, we generated 43 new YFV genomes sampled from humans, non-human primates (NHP), and primarily, mosquitoes from highly heterogenic areas in 15 localities from Rio de Janeiro (RJ) state during the YFV 2016-2019 outbreak in southeast Brazil. Our analysis revealed that the genetic diversity and spatial distribution of the sylvatic transmission of YFV in RJ originated from at least two introductions and followed two chains of dissemination, here named the YFV RJ-I and YFV RJ-II clades. They moved with similar dispersal speeds from the north to the south of the RJ state in parallel directions, separated by the Serra do Mar Mountain chain, with YFV RJ-I invading the north coast of São Paulo state. The YFV RJ-I clade showed a more significant heterogeneity across the entire polyprotein. The YFV RJ-II clade, with only two amino acid polymorphisms, mapped at NS1 (I1086V), present only in mosquitoes at the same locality and NS4A (I2176V), shared by all YFV clade RJ-II, suggests a recent clustering of YFV isolates collected from different hosts. Our analyses strengthen the role of surveillance, genomic analyses of YVF isolated from other hosts, and environmental studies into the strategies to forecast, control, and prevent yellow fever outbreaks.
