Lutzomyia longipalpis behavior and control at an urban visceral leishmaniasis focus in Argentina Comportamento e controle de Lutzomyia longipalpis em foco de leishmaniose visceral urbana na Argentina

During the earlier stages of visceral leishmaniasis transmission in Posadas City, Misiones, both the night activity and attraction to humans of Lutzomyia longipalpis were assessed, in order to provide preliminary recommendations. The impact of peridomestic deltamethrin spraying performed by local of...
