Previous research has documented low frequencies of interspecific mating in nature between the invasive vectors Aedes aegypti and Aedes albopictus. It is also known that heterospecific male accessory gland substances transferred during mating sterilize A. aegypti but not A. albopictus females, leading to satyrization, a form of reproductive interference. This paper demonstrates that satyrizatio...

Previous studies have demonstrated that the synthesis of juvenile hormone (JH) by the isolated corpora allata (CA) complex in vitro as well as the JH titer in the yellow fever mosquito Aedes aegypti are elevated before feeding and low after a blood meal. In the present study, we used an in vitro radiochemical assay to analyze the effect of farnesoic acid (FA) and Aedes allatotropin (Aedes-AT) o...

A study was made of the oviposit behavior of gravid female Aedes mosquitos in man-made habitats under field conditions. The study showed that the gravid female Aedes mosquitos preferred containers with relatively easy access but not too open to external environmental influence. The dark surface of the containers served as the initial and long-range attractant to the breeding sites. Volatile che...

Two larvae of Aedes scapularis were found in an artificial breeding site, in the Sertaneja County, North of the Paraná State, South Brazil, in the course of routine work for the control of dengue vectors.

Zika virus transmission is primarily vector-borne, mainly via Aedes mosquitoes. The virus can also be found in various body fluids and transmission by sexual contact has also been reported. Aedes aegypti, the principal vector, is found in tropical and subtropical climates and adapts well to urban areas, living in and around human habitations. The areas affected by Zika virus lie within areas af...

A study was conducted to compare responses of male and female Aedes aegypti (Linn.) and Aedes taeniorhynchus (Wiedemann) to 9 olfactory repellents in the World Health Organization insecticide irritability test system. An irritant insecticide (permethrin) and a control were included for comparison. Aedes aegypti exhibited significantly more takeoffs than Ae. taeniorhynchus, and female mosquitoes...

The spatial distribution of Aedes aegypti and Aedes albopictus in environmental and geographical zones, e.g., urban-rural, coastal-mountainous, and north-south, was investigated throughout Vietnam. Immature stages were collected from used tires along roads. The effects of regions, seasons, and the degree of urbanization on the density and the frequency were statistically analyzed. Aedes aegypti...

INTRODUCTION Yellow fever is a non-contagious infectious disease, highly lethal, transmitted by the Aedes, Haemagogus and Sabethes. METHODS Descriptive retrospective study of the yellow fever cases in Amazonas, between 1996 and 2009. RESULTS Forty two cases of yellow fever were confirmed, with 30 deaths, 10% of which were foreigners. CONCLUSIONS The presence of Aedes aegypti and Aedes alb...
