Susceptibilidad dE Lutzomyia verrucarrum a piretroides en zonas endémicas de Enfermedad de Carrión de Ancash

Carrion disease is an endemic vector-borne infection of Peru, the vector control of the Lutzomyia verrucarum with insecticides is one of the most commonly used to reduce morbidity. It was determined the susceptibility of this vector to the most pyrethroids widely used (cyfluthrin, alfacypermethrin and deltamethrin) in two endemic areas of highlands from Ancash (Llumpa: 3200 and Maya: 2600 meters above sea level), Peru in June 1999. Were exposed to 50 mosquitoes from each area and insecticide, using an anopheline contact test modified. We found a mortality rate of 100% for each pyrethroid tested. While total susceptibility of L. verrucarum showed, is necessary the implement of surveillance to insecticides resistance as is done with other vectors in Peru..
