摘要

The preparation process and the application of the microcapsules obtained biomass with potential larvicidal activity against northeastern the mosquitoes that transmit dengue fever.The present invention patent refers to the preparation and obtaining of new microcapsules, effective in the prevention and control of mosquito vectors of disease of great social impact, such as dengue, using as a material called galactomana natural polysaccharide encapsulant. In,Extracted from endospermas of legume seed of the species Adenanthera pavonina and liquid of the shell of cashew nuts (natural or technical), LCC, and its main constituents, cardanol (5 - N - pentadecilfenol), cardol (5 - N - pentadecilresorcinol) and new biomolecules organofosforadas alongside IRR the synthesis of cardol with reagent dietilclorotiofosfato,Acting as bioactive products with activity or material of the core.After the preparation of the emulsions with concentrations determined in proportion to 10: 1 (MLV) material of the wall / core materials, spray drying and obtaining of the microcapsules, bioassays, in triplicate were performed with larvae of 30 stage of eggs of Aedes aegypti using 30 Larvae and reading of mortality observed after 24.48 and 72 hours in accordance with the standards set by the World Health Organization (who, 2006). It has been observed that in all tests was an effective larvicidal activity of the new bioestruturas microencapsulated with LC50 lower than 100 ppm and, thus, 100% mortality after one week.These results are good prospects for the use and use of new materials in the fight against larvae of Aedes aegypti 1 control.
