| Abstract (English): | Introduction: In Colombia, periurban populations of Lutzomyia longipalpis, vector of the causative agent of visceral leishmaniasis in the upper and middle valley of the Magdalena River, may be exposed to insecticide applications with different purposes. Thus, it is important to begin a susceptibility surveillance of this species to insecticides. Objective: To determine indicators of susceptibility to three insecticides habitually used in public health, such as malathion, deltamethrin and lambda-cyhalothrin in an experimental strain of L. longipalpis. Materials and methods: We used the method proposed by the Centers for Disease Control and Prevention. Groups of 10 to 15 unfed females were exposed to different concentrations of the insecticides using 250 ml glass bottles as test chambers. Mortality was registered every five minutes for an hour. Diagnostic concentrations and lethal times for each insecticide were calculated. Results: In the evaluated L. longipalpis strain, the diagnostic concentrations and times were 75 μg/ ml and 25 minutes for malathion, 10 μg/ml and 35 minutes for deltamethrin, and 15 μg/ml during 30 minutes for lambda-cyhalothrin. Conclusions: Baseline data over mortality response to three insecticides were established in a susceptibility strain of L. longipalpis vector. These indicators will allow establishing comparisons with populations of L. longipalpis exposed regularly or sporadically to chemical control measures to detect changes in their resistance to these insecticides.

| Abstract (Spanish): | Introducción. En Colombia, las poblaciones periurbanas de Lutzomyia longipalpis, vector del agente causal de la leishmaniasis visceral en el valle alto y medio del río Magdalena, pueden estar expuestas a aplicaciones de insecticidas con diferentes propósitos, por lo que es importante iniciar una vigilancia de la sensibilidad de esta especie a los insecticidas. Objetivo. Determinar en una cepa experimental de L. longipalpis los indicadores de sensibilidad (concentraciones y tiempos diagnósticos) para tres insecticidas de uso común en salud pública: el malatión, la deltametrina y la lambdacialotrina. Materiales y métodos. Se utilizó el método propuesto por los Centers for Disease Control and Prevention. Grupos de 10 a 15 hembras se expusieron a diferentes concentraciones de los insecticidas, utilizando botellas de vidrio de 250 ml como cámaras de prueba. La mortalidad se registró cada cinco minutos durante una hora. Se calcularon las concentraciones y los tiempos diagnósticos para cada insecticida. Resultados. En la cepa evaluada de L. longipalpis, las concentraciones y los tiempos diagnósticos fueron de 75 μg/ml y 25 minutos para el malatión, de 10 μg/ml y 35 minutos para la deltametrina y de 15 μg/ml y 30 minutos para la lambdacialotrina. Conclusión. Se estableció la línea base de la mortalidad frente a tres insecticidas en una cepa sensible del vector L. longipalpis. Estos indicadores permitirán establecer comparaciones con poblaciones del vector expuestas regular o esporádicamente a medidas de control químico y detectar, así, cambios en la sensibilidad de esta especie a los insecticidas.
