Summary: | Aedes aegypti mosquito, popularly known as the dengue mosquito, represents a serious public health problem, because it is the vector responsible for several serious diseases such as Chikungunya fever, Zika virus and Dengue, the latter of which has a higher incidence in the Brazilian population. That mosquito has a high capacity for adaptation in the most diverse types of environments, mainly in places with high population density and lack of basic sanitation, factors that favor its proliferation. The control methods used by the epidemiological surveillance agencies are divided into three modalities: mechanical control, chemical control and biological control. Among the biological control methods, the Sterile Insect Technique (SIT) technique stands out, which consists of introducing sterile males into the mosquito population. This article presents reproduction analyzes of a population of natural mosquitoes compared to a population of mosquitoes with the insertion of males sterilized by ionizing radiation, seeking to observe the impact caused by this control method. The statistical analyzes showed the Negative Binomial regression model presented a better fit to the daily egg count data, when this model was compared to the Poisson model. In addition, the introduction of irradiated males decreases the average oviposition rate by approximately 30%.
O mosquito Aedes aegypti, popularmente conhecido como mosquito da dengue, representa um sério problema de saúde pública, pois é o vetor responsável por diversas doenças graves, como febre Chikungunya, vírus Zika e dengue, sendo esta última de maior incidência na população brasileira. Este mosquito possui alta capacidade de adaptação nos mais diversos tipos de ambientes, principalmente em locais com alta densidade populacional e falta de saneamento básico, fatores que favorecem sua proliferação. Os métodos de controle utilizados pelos órgãos de vigilância epidemiológica são divididos em três modalidades: controle mecânico, controle químico e controle biológico. Entre os métodos de controle biológico, destaca-se a Técnica de Inseto Estéril (SIT, Sterile Insect Technique), que consiste na introdução de machos estéreis na população de mosquitos. Este artigo apresenta análises de reprodução de uma população de mosquitos naturais comparada a uma população de mosquitos com a inserção de machos esterilizados por radiação ionizante, buscando observar o impacto causado por este método de controle. As análises estatísticas demo |
