 en Biology, Diversity and Strategies for the Monitoring and Control of Triatomines - Chagas Disease Vectors
Costa, Jane & Lorenzo, Marcelo

Abstract

Despite the relevant achievements in the control of the main Chagas disease vectors Triatoma infestans check for this species in other resources and Rhodnius prolixus check for this species in other resources , several factors still promote the risk of infection. The disease is a real threat to the poor rural regions of several countries in Latin America. The current situation in Brazil requires renewed attention due to its high diversity of triatomine species and to the rapid and drastic environmental changes that are occurring. Using the biology, behaviour and diversity of triatomines as a basis for new strategies for monitoring and controlling the vectorial transmission are discussed here. The importance of ongoing long-term monitoring activities for house infestations by T. infestans, Triatoma brasiliensis check for this species in other resources , Panstrongylus megistus check for this species in other resources , Triatoma rubrovaria check for this species in other resources and R. prolixus is also stressed, as well as understanding the invasion by sylvatic species. Moreover, the insecticide resistance is analysed. Strong efforts to sustain and improve surveillance procedures are crucial, especially when the vectorial transmission is considered interrupted in many endemic areas.
