Dengue & Transmitter Discipline

According to WHO globally dengue disease is 10th most informal justification of mortality Two-third of the mankind aggregation is at attempt of contracting dengue feverishness. There are 50 -100 million cases of dengue fever apiece year. Dengue symptom (DF) and dengue hurt fever (DHF) are caused by dengue viruses (genus Flavivirus; unit Arbovirus). Dengue viruses are elflike, single-stranded, RNA viruses. There are cardinal antigenically-related but crystalline serotypes, dengue 1, dengue 2, dengue 3 and dengue. This virus enters the weak body through the grip of Aedes mosquito that expect one of the quadruplet strains of dengue virus.

There are basically two strategies employed:

1. Reflection of vector collection

2. Assessment of feasible larvicidal state of several elect position extracts

On the hit of above strategies and experiments we over that A. Squamosa and A. Indica are Nifty inhibitors of mosquito (Aedes aegypti) enculturation. Regularize if temephos seems to be much impelling,leaves extracts are bio degradable, environmentally unhazardous and non virulent to humans as compared to synthetic insecticides specified as Temephos or DDT.This reflection gift cater to render part for processing solon telling prevention strategy including bio environmental factors prudent for mosquito fostering & new mosquito moderate measures.

Search papers highlighting this problem and thinkable solutions were presented in Human conferences on examination microbiology and bioengineering: IAMM, 2004, Bombay and Anna university Biotechexcellence 2005, Madras, respectively. As far as culicidae folk is preoccupied knowledge of developmental bioscience is limited. Thence it is necessary to rumination and try to qualify the mosquito employment in a specified a way that mosquitoes give be established as friends of imperfect form and not nuisance.
