| Popis: |
Most of the human infections with Trypanosoma cruzi are caused by triatomine species adapted to thrive in domestic habitats and blood-feed on humans. Residual house spraying with insecticides applied by public health personnel remains the mainstay of triatomine control, with pyrethroids being in use for nearly 40 years. Here, we review the vector control methods applied to triatomines of public health relevance. We examine the effectiveness and epidemiological impact of residual house spraying and housing improvement, and its main limitations, and focus on the reinfestation process and the putative sources of reinfestants. High levels of pyrethroid resistance associated with triatomine control failures appeared in the late 1990s and so far have remained restricted to northern Argentina and Bolivia. Peridomestic foci and effective vector surveillance at low bug densities remain the Achilles’ heel of triatomine control programs. Other insecticide delivery systems of limited use include disposable fumigant canisters and insecticidal paints. Housing improvements and other multisectoral measures directed to prevent house colonization have not been exploited to its full potential and may play an important role for sustainable vector control across diseases. Integrating vector and disease management efforts may be the key to long-term program sustainability in the affected areas. |
