Visceral leishmaniasis control in Brazil: time to re-evaluate DDT?

Controlling visceral leishmaniasis in Brazil has proven difficult for several reasons, including: 1) limitations in diagnosis and treatment, 2) the failure of the dog culling program, and 3) the short-term residual effect of pyrethroids against the main phlebotomine vectorLutzomyia longipalpis. The disease has become more widespread during the last three decades and it now occurs in 21 of the 26 Brazilian states plus the Federal District, and even affects several state capitals and large cities. Although DDT has many environmental drawbacks and possible toxicity to animals, several countries still use this chemical in their public health programs due to its long-lasting effect. Therefore, this study aims to re-evaluate the use of DDT to control zoonotic visceral leishmaniasis.

Introduction:Despite the recommendations by interpretation of resistance ratios obtained in laboratory bioassays, little is known about the actual impact of these results in the effectiveness of vector control activities in the fi eld. In this context, our objective was to determine the mean value of different resistance ratios obtained by laboratory bioassays performed as part of the chemical control strategies of Triatoma sordida in the fi eld. Methods: Field bioassays were developed in Monte Azul and Coração de Jesus (Southeast, Brazil). In each location, samples were formed with three domestic units treated with alpha-cypermethrin 20.0% (Alfatek ® 200 SC). One day after spraying, 10 fi fth-instar nymphs remained in contact with the surfaces treated (adobe with plaster, adobe without plaster, or wood) with insecticide in plastic cones for 72h. Three cones were exposed inside the intradomicile and the peridomicile. The insects in the control group were exposed to an insecticide-free piece of cardboard. Mortality was measured 72h after removal of the insects from the treated surfaces. The tests were realized in triplicate. Results: Mortality was 100.0% in all locations, except for Monte Azul; Landinho (96.6%) and Coração de Jesus; Barriguda (96.6%). Conclusions: Although the resistant populations in laboratory tests proved to be susceptible in the fi eld, this observation is not suffi cient to suggest that the cut-off points used to justify the resistance ratio should be changed. In this sense, we recommend that laboratory and fi eld bioassays are carried out with a greater number of Triatominae populations to allow more in-depth consideration of the subject.
