[Effect of larvae density on adult size of Aedes aegypti reared under laboratory condictions].
نویسندگان
چکیده
To evaluate the influence of larval density in development of Aedes aegypti mosquitoes we evaluated three different densities. It was observed that conditions of high larval density and shortage of food produced a reduction in the size of adults and increased mortality rate of Aedes aegypti in laboratory conditions.

Dengue is a vector-borne disease caused by dengue virus. According to the recent report of CDC that one-third population of the world are at high risk with Dengue fever. The prevalence of the dengue hemorrhagic fever was found more in tropical and sub-tropical regions of the world. Aedes mosquitoes was reported as the main cause of transmission of dengue virus. So the current study was planned ...
متن کاملEffects of larval nutrition on the host-seeking behavior of adult Aedes aegypti mosquitoes.
Adult female Aedes aegypti that were reared on a suboptimal diet as larvae were less likely to engage in host-seeking behavior than were adults derived from larvae reared on an optimal diet. A postemergence carbohydrate diet of either 1 or 10% sucrose solution did not affect this response. When the progeny of field-collected Aedes vexans were reared in the laboratory, the adults were significan...

This study was conducted to determine the effects of increased water temperatures on the development of Aedes aegypti immatures under laboratory conditions in Trinidad, West Indies using temperature regulated water baths to cover a range of temperatures from 24-25°C to 34-35°C at a relative humidity of 80%. Two experiments were designed: (1) at constant temperature regimens and (2) under diurna...

Mosquito midgut plays a crucial role in its vector susceptibility and pathogen interaction. Identification of the sustainable microflora of the midgut environment can therefore help in evaluating its contribution in mosquito-pathogen interaction and in turn vector competence. To understand the bacterial diversity in the midgut of Aedes aegypti mosquitoes, we conducted a screening study of the g...
