Análise da liberação do inseticida Malathion, usado para o combate e controle do vetor transmissor da dengue no estado do Tocantins

Abstract

Diseases transmitted by hematophagous insects, mainly Culicidae and Phlebotominae, continue to create major public health problems, especially in the tropical and subtropical regions of the world. Despite efforts to control vector populations, the incidence of arboviruses, protozooses and helminths has increased significantly in the last two decades. Estimates by the World Health Organization (WHO) indicate that mosquito-borne diseases are among the leading causes of morbidity and mortality in developing countries. The objective of this paper is to analyze the impact of the use of malathion EW 44% on the control of dengue in the state of Tocantins, from January 2014 to October 2019. To this end, a descriptive study was conducted, based on data from insecticide releases, complementing with the records of the probable cases of dengue registered in the epidemiological bulletins of the State of Tocantins of the period referred to above. Statistical analyzes were performed using the Windows Excel program version 10 and the Statistical Package for the Social Sciences (SPSS) version 21. In the discussion of this study we described the impact of dengue resulting from spatial spraying with 44% malathion EW performed in the state. The lack of a tool for monitoring and evaluating the quality of the execution of spatial sprays performed in the municipalities was also noted, as well as the monitoring of the susceptibility of the vectors related to the insecticide used.
