Larval habitat/oviposition behavior

(1) Artificial containers; (2) natural containers; (3) natural groundwater—shallow; (4) natural groundwater—deep; (5) tree hollows; (6) perforated bamboo; (7) cut bamboo; (8) skip oviposition

Drives survival and dispersion of the offspring; inter- and intraspecific competition during larval development; environmental requirements for specific breeding sites; domiciliation capacity

[24, 50, 72,73,74,75,76,77,78,79,80,81]

Egg resistance to desiccation

Resistant; nonresistant

Indicates the ability to wait for favorable conditions for immature development

[24, 48, 72,73,74]

Larval development speed

Fast (up to 10 days); slow (more than 10 days)

Determines the immature survival (or not) in temporary breeding sites; sudden population increases

[24, 72, 78,79,80,81]

Host preference

Primatophilic; ornithophilic; eclectic/opportunistic

Related to the probability of transmitting certain pathogens between host groups (e.g., YFV transmission to human and nonhuman primates by primatophilic mosquitoes), and interspecific competition

[24, 55, 82,83,84,85]

Main hourly biting activity

Diurnal; nocturnal; twilight/eclectic

Reflects the period of activity, the behavior of mosquitoes, and the finding of hosts and interspecific competition

[24, 26, 78, 86, 87]

Vertical distribution in the forest

Mostly on the ground level; mostly at the tree canopy; eclectic/opportunistic (canopy and ground)

Determines both breeding sites and exploited hosts. Eclectic mosquitoes can serve as bridge vectors of pathogens from canopy-dwelling hosts to ground-dwelling hosts and vice versa

[88,89,90,91,92,93,94]

Seasonal distribution

Accentuated (abrupt population peaks); moderate (no abrupt peaks)

Populations increase abruptly in response to certain environmental events (e.g., rain, temperature), which increases vectorial capacity and determines the most favorable periods for transmission of pathogens

[50, 60, 72, 78, 87, 92, 95,96,97,98,99]

Environment

Forest interior; forest edge; peri-urban; urban

Ability to withstand different degrees of environmental impact and ecological impoverishment. Also reflects anthropophily and interspecific competition

[46, 60, 83, 94, 98, 100]

Epidemiological importance

YFV natural infection; YFV transmission in experimental infections; YFV primary vector; YFV secondary or local vector

Indicates the accumulated evidence for vector competence and vectorial capacity of the species
