DENGUE: análise de substâncias atóxicas e não poluentes no combate ao Aedes Aegypti

Abstract

Dengue is currently considered a serious disease and of great concern to public health agencies. It is a pathology that requires special care and so far does not have specific drugs or vaccine. It is transmitted by vector, the mosquito Aedes aegypti, a free-living insect that depends on clean water and stops for its reproduction. Currently, the work to combat the vector is carried out using toxic chemicals that can cause damage to humans and the environment. Its prolonged use on a large scale has provoked vector resistance. The objective of this work is to analyze non-toxic and non-polluting substances such as dry lime sludge, sodium hypochlorite and sodium chloride that can be used as alternative means to combat the vector. For this purpose, larvae were collected from contaminated sites. The concentration of the substances used was 30.0% (m/s) of coffee grounds in water 1.5% (v/v) of sodium hypochlorite in water and 3.0 (m/v) of sodium chloride in water . The results observed were that coffee grounds proved to be more efficient than hypochlorite and sodium chloride for both pupae and larvae, responding satisfactorily among the three substances tested, and can be safely used in combating the vector.
