Larvicidal Activity of Combretum Collinum Fresen Against Aedes Aegypti (Short Research Communications‪)‬

Despite of the fact that dengue outbreaks in the tropics have been worldwide for over 200 years, it is still the most important mosquito transmitted viral disease affecting man1. Aedes aegypti (Diptera: Culicidae) is an arbovirus vector responsible for yellow fever in central and south America and in west Africa. It is also the vector for dengue hemorrhagic fever (DHF), endemic to south-east Asia, the Pacific Islands, Africa and the Americas (1). It is estimated that 2.5 billion people are currently at risk for dengue fever (DF), DHF, and dengue shock syndrome (DSS) (1). The size and spread of the dengue pandemic, the unpredictability of the epidemic occurrences and the circulation of virulent and non-virulent strains make DHF/DSS a model for emerging infectious disease. Despite of this challenge, the development of dengue virus vaccines is still a long way to be of any use due to several obstacles (2).
