Potential for Organophosphate Resistance in Aedes aegypti (Diptera: Culicidae) in the Caribbean Area and Neighboring Countries

Susceptibilidade larval de duas populações de Aedes egypti a inseticidas químicos

“…Dessa forma, diversos casos de resistência têm sido registrados no mundo para espécies de mosquitos vetores 3,6,11,13,14,17 e, mais particularmente, para populações de Aedes aegypti no Brasil. 1,9,10 Além da detecção de resistência para a formulação das estratégias de controle, também é fundamental o conhecimento dos seus mecanismos.…”

Evaluación de ovitrampas para vigilancia y control de Aedes aegypti en dos centros urbanos del Urabá antioqueño

“…La presión química ejercida sobre las poblaciones de A. aegypti ha generado resistencia en las poblaciones del mosquito en 41 países de América y el Caribe (21)(22)(23)(24), así como en otros lugares del mundo (25,26), y se estima que la especie es resistente a 24 compuestos químicos diferentes (26).…”

Impact of environmental temperatures on resistance to organophosphate insecticides in Aedes aegypti from Trinidad

“…This has been due, in part, to the interaction of several risk factors related to the environment, the virus, the host population, and vector bionomics (3)(4)(5), and to the widespread development of insecticide resistance in the Aedes aegypti mosquito (6,7). Mosquitoes and other poikilothermic vector organisms are sensitive to climatic factors such as temperature, precipitation, and humidity (8).…”

“…Organophosphate (OP) insecticides such as fenthion, malathion, and temephos have been used in the Caribbean region to control A. aegypti for the last 40 years (6). However, the continued reliance on these insecticides has resulted in the development of mosquito resistance to the insecticide, which has created a problem for vector control programs (3,6,19).…”
