Behaviour Of Anopheles Gambiae S.L. To Different Concentrations Of Insecticide, Kingasani District, Kimbanseke Commune, City Of Kinshasa, Dr Congo

Abstract

The results of these investigations reveal that the waste management and environmental sanitation system in place in the Commune of Kimbanseke and specifically in the Quartier Kingasani is inefficient and consequently has health and environmental weaknesses, which would mean it is not environmentally friendly.

This is due to a number of variables, including poor use of LLINs and insecticides, insalubrity, the absence of a genuine environmental management policy, mesological education, entomological surveillance and ongoing public awareness-raising.

The study of the resistance of Anopheles vectors of malaria subjected to different concentrations of insecticides in the Quartier de Kingasani, Commune de Kimbanseke, city of Kinshasa in DR Congo consisted firstly of a larval prospection and localization of larval sites, obtaining adults after rearing in the insectarium, which allowed the realization of sensitivity tests in order to observe the behavior of Anopheles facing different concentrations of insecticides and to highlight the rate of resistance.

Among the five insecticides exposed to Anopheles, these mosquitoes were highly sensitive to three insecticides (Alpha cypermethrin 0.5%, bendiocarb 0.1% and deltamethrin 0.05%), but showed resistance to two insecticides (Permethrin 0.75% and pirimiphos methyl 0.1%).

Thus, it is clear that the misuse of LLINs and a variety of insecticides from unknown sources, sold to markets could be the main cause of the increased resistance of Culicidae and sometimes other arthropods of medical interest in the Kingasani micro ecosystem.
