Nos três primeiros períodos, a mudança nas proporções das referidas espécies ocorreu, possivelmente, devido ao impacto das alterações introduzidas no meio ambiente, visto que Nyssomyia neivai se adapta melhor nos ambientes com alto grau de antropia.…”

“…Although some studies reported deltamethrin residual effects up to 9-12 months inside houses 13,19 , strong anti-feeding effects when applied to dogs as collars or topically, and repellent effects in impregnated bednets 7,8,9 , and pyrethroids as lambdacyalothrin reducing impact on Lu. longipalpis sand fly captures after focal or indoor applications 14,18 , there are many reports about the short or transient effects of fenitrothion 14 , cypermethrin 12 and deltamethrin as peridomestic sprayed insecticide 1,13,22,36 . Unfortunately the effects of insecticides for longer periods than 14 days could not be assessed in this study due to an abrupt change in the weather conditions that reduced the population; both in the intervention and the control group, but the results obtained were consistent with the literature.…”

SUMMARYDuring 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/m 2 ) 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.

“…This suggests that the lack of information about VL among the public at large, and among health professionals in particular, is a major drawback in reducing the severity of this disease. An aggravating contributing factor is the disorganization of public agencies and the constant replacement of vector control specialists by health agents, what causes a shortage of qualifi ed staff for control work (Teodoro et al 2007).…”

“…Through inexpensive alternatives and practical measures that can be incorporated into the routine of people living in high-risk areas, the incidence of leishmaniasis can be lowered. That means that more effective prevention and control of these vectors requires evaluation of the public health efforts effectiveness and the participation of community in their implementation (Teodoro et al 2007).…”

Controle de Flebotomíneos (Diptera: Psychodidae) Vetores de Leishmanioses RESUMO -Os fl ebotomíneos são vetores de importância médica e veterinária, podendo transmitir leishmanioses, bartoneloses e algumas arboviroses. A adaptação de algumas espécies a locais que passaram por modifi cações humanas as aproxima dos domicílios, podendo facilitar a transmissão das doenças, e as estratégias adotadas para seu controle têm sido controvertidas. No tocante às leishmanioses, por exemplo, o que sustenta a utilização do controle vetorial e de reservatórios como estratégias de intervenção é a conjectura de que a incidência de infecção em humanos está diretamente relacionada ao número de cães infectantes e a fatores entomológicos. Dessa forma, o controle do vetor pode então oferecer solução menos onerosa e mais prática, o que conduziria a medidas preventivas efi cazes em um maior número de focos de leishmaniose. Não obstante, na complexidade dos fatores envolvidos, o controle químico continua sendo indispensável e o uso de inseticidas biológicos e plantas inseticidas, por exemplo, representam áreas de estudo a serem incentivadas e desenvolvidas, pois apresentam resultados promissores. A análise em questão representa uma oportunidade de avaliação das medidas até então adotadas, principalmente em relação aos métodos e à efi cácia dos componentes entomológicos dos programas de controle das leishmanioses. PALAVRAS-CHAVE: Antropozoonose, Lutzomyia, PhlebotomusABSTRACT -Phlebotomines are of medical and veterinary concern as they vector leishmaniasis, bartonellosis and some arboviruses. The adaptations of some species to places modifi ed by humans bring these vectors into contact with dwellings, which can facilitate disease transmission, and the vector control strategies adopted have rendered controversial results. Regarding leishmaniasis, for instance, which vector and reservoirs control can be effective, there is an assumption that the incidence of human infection is directly related to the number of infectious dogs, as well as to entomological factors. Therefore, vector control can provide a cheaper and more practical solution to prevent cases of leishmaniasis. Nevertheless, due to the complexity of the factors involved, chemical control is still essential, and biological insecticides and insecticide plants, for example, represent areas for study that should be encouraged and developed since they show promising results. This paper summarizes the control strategies adopted so far, especially the methods and effi ciency of the entomological components of leishmaniasis control programs.
