Adult Control
Dengue, Zika and chikungunya are serious public health problem in tropical and subtropical countries, including Colombia. There, dengue epidemics are periodic (more than 70 thousand cases in 2022), and Antioquia is one of the departments with the highest number of cases. These arboviral diseases are transmitted to humans by bites of Aedes mosquitoes, mainly Ae. aegypti, and in the absence of a vaccine, health entities focus mainly on vector control using insecticides, including Insect Growth Regulators (IGR). Novaluron, a kind of IGR, has proven to be effective in vector control. In order to determine the optimal application dose of Novaluron 0.2G on the emergence of Ae. aegypti in an urban area endemic for dengue of Antioquia (Carepa, Urabá region) this study was done. Twenty-one dwellings were randomly selected, where three 250-L tanks were located, two corresponded to treatments and one to control, evaluating three concentrations (treatments), randomly selected for each dwelling. The study was carried out for 18 weeks: seven weeks of pre-treatment, one week of product application and ten weeks of post-treatment. For this, the pupae of Ae. aegypti were collected, allowing the emergence of adult mosquito under controlled conditions, in order to estimate the weekly inhibition of the emergence. The results indicated that a reduction in the emergence of Ae. aegypti of close to 100% was achieved with the highest concentration evaluated (0.584 mg/L). For the other concentrations (0.292 and 0.146 mg/L), the percent inhibition of emergence for week two was 79% and 45%, respectively. These results are very useful to support vector control in dengue endemic cities.
