Zusammenfassung: | The ineffectiveness of current strategies for chemical control of mosquito vectors raises the need for developing novel approaches. Thus, we carried out a literature review of strategies for genetic control of mosquito populations based on the sterile insect technique. One of these strategies consists of releasing radiation-sterilized males into the population; another, of integrating a dominant lethal gene under the control of a specific promoter into immature females. Advantages of these approaches over other biological and chemical control strategies include: highly species-specific, environmentally safety, low production cost, and high efficacy. The use of this genetic modification technique will constitute an important tool for integrated vector management.Original Abstract: Formas quimicas de controle de mosquitos vetores sao ineficazes, levando ao desenvolvimento de novas estrategias. Assim, foi realizada revisao das estrategias de controle genetico de populacoes de mosquitos vetores baseada na tecnica do inseto esteril. Uma delas consiste na liberacao de machos esterilizados por radiacao, a outra, na integracao de um gene letal dominante associado a um promotor especifico de feneas imaturas. Entre as vantagens sobre outras tecnicas biologicas e quimicas de controle de vetores estao: alta especificidade, nao prejudicial ao meio ambiente, baixo custo de producao e alta eficacia. O uso desta tecnica de modificacao genetica pode vir a ser uma importante ferramenta do manejo integrado de vetores. |
