INFLUENCE OF CLIMATIC FACTORS ON THE POPULATION DYNAMICS OF HAEMAGOGUS JANTHINOMYS (DIPTERA: CULICIDAE), A VECTOR OF SYLVATIC YELLOW FEVER [PDF]

Entomological News, 2010
ABSTRACT: The influence of three climatic variables (temperature, air humidity and rainfall) on the incidence of populations of Hg. janthinomys in two geographical regions of Brazil, in the states of Goias and Tocantins, was studied from February 1996 to December 1997.

Microclimate and the vertical stratification of potential bridge vectors of mosquito‑borne viruses captured by nets and ovitraps in a central Amazonian forest bordering Manaus, Brazil

Scientific Reports, 2021
In the Americas, some mosquito-borne viruses such as Zika, chikungunya, and dengue circulate among humans in urban transmission cycles, while others, including yellow fever and Mayaro, circulate among monkeys in sylvatic cycles.

Neotropical Sylvatic Mosquitoes and Aedes aegypti Are Not Competent to Transmit 17DD Attenuated Yellow Fever Virus from Vaccinated Viremic New World Non-Human Primates

Viruses, 2022
Beside humans, thousands of non-human primates (NHPs) died during the recent outbreak caused by the yellow fever virus (YFV) in Brazil. Vaccination of NHPs against YFV with the YF 17DD attenuated virus has emerged as a public health strategy, as it would

COI DNA barcoding to differentiate Haemagogus janthinomys and Haemagogus capricornii (Diptera: Culicidae) mosquitoes

Acta Tropica
The genus Haemagogus (Diptera: Culicidae) includes species that are important vectors of pathogens such as the yellow fever virus. The accurate identification of these species is essential for the control of zoonoses. Females of Hg. capricornii and Hg. janthinomys are morphologically indistinguishable, which makes the use of alternative identification ...

Alphavirus nsP2: A Multifunctional Regulator of Viral Replication and Promising Target for Anti‐Alphavirus Therapies

Reviews in Medical Virology, Volume 35, Issue 2, March 2025.
ABSTRACT Alphaviruses are re‐emerging vector‐born pathogens that cause arthralgia or encephalitic diseases on a global scale. While a vaccine against chikungunya virus was recently approved, no vaccines currently exist for other alphaviruses, nor are there antiviral drugs for the treatment of alphavirus infections. Alphaviruses have positive‐strand RNA
