Despite a large body of knowledge about the evolution of life histories, we know little about how variable food availability during an individual's development affects its life history. We measured the effects of manipulating food levels during early and late larval development of the mosquito Aedes aegypti on its growth rate, life history and reproductive success. Switching from low to high fo...

This study had the aim of evaluating the effects of intra and interspecies larval competition between Aedes aegypti and Aedes albopictus, survival of larvae time taken to develop and wing length. The experiment was carried out with three densities and five proportions of the species. Aedes aegypti survival was greater than Aedes albopictus survival at intermediate density, while it was lower at...

background : the population of mosquitoes is mainly influenced by the biotic and abiotic factors. although aedes aegypti was reported until 1960’s in the punjab, pakistan, the population has increased dramatically since 2009 and caused severe epidemics in 2011 due to heavy floods and rains. thus, this study was carried out to know the effect of biotic and abiotic factors on the population of ae...

A total of 73 localities covering 4,894 premises and 26, 712 breeding habitats were surveyed in 1980 to determine and establish the density and distribution pattern of Aedes aegypti and Aedes albopictus in Sarawak. A similar pattern has been observed in the density of the Aedes aegypti and Aedes albopictus. The number of houses positive with Aedes larvae were found to be highest in the coastal ...

OBJECTIVE To evaluate the monthly frequency of larvae and pupae of Aedes albopictus, Aedes aegypti and other mosquitoe species in tires, and the influence of environmental factors on that. METHODS The immature stages of mosquitoes were collected monthly from four tires in the municipality of Nova Iguaçu, Brazil, from November 1997 to October 1998. The following variables were measured: rainfa...

Reciprocal and homologous mating experiments between Malaysian Aedes aegypti and Aedes albopictus mosquitoes were conducted in the laboratory. Two methods were employed, namely an artificial mating technique and a natural cage mating technique. The study demonstrated there exists a strong reproductive isolation between Ae. aegypti and Ae. albopictus. Insemination occurred in cross-mating experi...

The Adultrap is a new trap built for capturing females of Aedes aegypti. Tests were carried out to evaluate the specificity of this trap in comparison with the technique of aspiration of specimens in artificial shelters. Adultraps were kept for 24 hours inside and outside 120 randomly selected homes in two districts of the city of Foz do Iguaçú, State of Paraná. The statistical test was Poisson...

To investigate the effect of NaCl concentration on the survival of Aedes aegypti larvae, samples of Aedes aegypti larvae were collected from some discarded container, artificial pool from the urban area of Wahga town and exposed to 10%, 15% and 20% of NaCl concentration. The results of this study suggest that NaCl higher concentration can be used in a more human non-lethal chemical approach and...

Between 2014 and 2016 more than 3,800 imported human cases of chikungunya fever in Florida highlight the high risk for local transmission. To examine the potential for sustained local transmission of chikungunya virus (CHIKV) in Florida we tested whether local populations of Aedes aegypti and Aedes albopictus show differences in susceptibility to infection and transmission to two emergent linea...
