Effects of hecogenin on Larvicidal activity against Aedes aegypti mosquito, the dengue vector
Background Dengue is a viral disease, caused by the dengue virus, a Flaviviridae family virus. Dengue is transmitted by several species of mosquito within the genus Aedes, principally A. aegypti. The dengue control is based on the mosquito combat, most of time through chemical insecticides. Hecogenin is a sapogenin present in the leaves of species from the Agave genus, with a wide spectrum of r...
متن کاملLimonoids as larvicidal components against mosquito larvae (Aedes aegypti Linn.).
The study focussed on four limonoids (calodendrolide, harrisonin, pedonin and pyroangolensolide) as larvicidal components against mosquito 2nd instar larvae of the species Aedes aegypti Linn. senso stricto. Since pyroangolensolide is close to calodendrolide in structure, it was synthesized through reduction of calodendrolide with chromium(II) chloride in acetone. Harrisonin and pedonin were ext...
متن کاملLarvicidal efficacy of leaf extracts of Heliotropium Indicum and Mukia maderaspatana against the dengue fever mosquito vector Aedes aegypti
Aedes aegypti is a vector of dengue fever, which is a public health problem in the world. During epidemics, emphasis is laid on the use of insecticides for controlling mosquitoes. The application of easily degradable plant compounds is considered to be one of the safest methods to control insect pests and vectors as an alternative to synthetic pesticides. A study was made to monitor the effect ...
متن کاملLarvicidal activity of Agave sisalana against Aedes aegypti mosquito, the dengue vector
Background Dengue is a viral systemic disease caused by an arboviral of Flaviviridae family, affecting about a 700 thousand cases per year in Brazil. It is endemic in tropical regions such as Southeast Asia, South Pacific, East Africa, Caribbean and Latin America. The disease is transmitted by Aedes aegypti (Linnaeus, 1762), a mosquito that is the main target for the disease control through str...
متن کاملA potent larvicidal agent against Aedes aegypti mosquito from cardanol.
Cardanol is a constituent of Cashew Nut Shell Liquid that presents larvicidal activity against Aedes aegypti. The isolation of cardanol is somewhat troublesome, however, in this work we describe an efficient and inexpensive method to obtain it as a pure material. The compound was used as starting material to make chemical transformation leading to saturated cardanol, epoxides and, halohydrins. ...
