Efecto insecticida de un recubrimiento de acción dual sobre contenedores de agua para el control de aedes aegypti en semicampo.

Abstract

The objective of this research work is to evaluate the insecticidal effect of a dual action coating (Alphacypermethrin and Pyriproxyfen) on Aedes aegypti under semi-field conditions, its theoretical basis is based on the study of the different viruses transmitted by Ae. aegypti. The methodology used was based on the use of a reference strain of Ae. aegypti Rockefeller reference strain, which is susceptible to insecticides, the sample size per bioassay was 100 Aedes females, which were divided into two equal groups, 50 for the exposed area and 50 for the control area, the additional bioassays were conducted with 400 larvae in lll instar to observe the behavior of the larvae and with 400 pupae to observe if there was emergence; Bioassays with eggs without contact with the coating were carried out to determine the development of the larvae from hatching; 500 Ae. aegypti eggs were used. aegypti eggs were used; the Excel tool was used for the analysis, which provided binomial probability as a mathematical basis and the factory characteristics of the coating to establish the value of success and failure of the experiment; among the results obtained, the main effect caused by the dual action insecticide coating was lethality in most of the individuals that were exposed; this result was also present in larvae and pupae; it was concluded that the insecticide coating in semi-field can be used as a chemical control tool in the different stages of the Ae. aegypti, even affecting its oviposition, making it possible to control the population from the immature stages.
