Resumo: 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 officials was also evaluated. Although Lu. longipalpis were found in traps located over a dog the entire night, 90% of the females were captured from 20.30h to 1.30h, and only landed on a human when he was at a distance of 1.5 m from the dog. Peridomestic spraying of deltamethrin (25 mg/m²) reduced the sand fly capture up to seven days post-intervention without dispersion in the border of the sprayed areas. These results support the recommendations about time-space focus of the protection measures: first half of the night, in the backyard, with pets and domestic animals kept at least 5 m from humans. The deltamethrin as it was used did not seem very effective in this scenario; neither did the eventual use of bed nets, at least in adults, due to the place/hour of sand fly higher activity. This study strengthens the need for a multidisciplinary approach to develop prevention strategies based both on biological and anthropological studies.

Durante os estádios precoces de transmissão da leishmaniose visceral na cidade de Posadas, Misiones, foi avaliada a atividade noturna da Lutzomyia longipalpis e a atração pelos seres humanos, para fornecer recomendações preliminares. O impacto do inseticida deltametrina peridoméstico, e a borrifação executada por funcionários locais, também foi avaliada. Embora existam Lu. longipalpis atingindo as armadilhas localizadas perto de um cão durante toda a noite, 90% das fêmeas foram capturadas a partir das 20.30h até 1.30h, e só atinge seres humanos quando estão a 1,5 m do cão. A borrifação peridoméstica com deltametrina (25 mg/m²) reduziu a área de captura da mosca da areia, até sete dias após a intervenção, sem dispersão nas bordas das áreas pulverizadas. Estes resultados apóiam as recomendações sobre o tempo-espaço, das medidas de proteção: na primeira metade da noite, no quintal, com animais de estimação criados pelo menos a cinco metros de distância dos seres humanos. A deltametrina como ela é usada, não parece muito eficaz neste cenário, nem o eventual uso de mosquiteiros pelo menos em adultos, devido ao lugar/hora de mais alta atividade de vôo da Lu. longipalpis. Este estudo acentua a necessidade de abordagem multidisciplinar, para desenvolver estratégias de prevenção baseadas tanto em estudos biológicos como antropológicos. Universidade de São Paulo.
