Abstract: Abstract. Chagas disease is a major vector-borne disease, and regional initiatives based on insecticide spraying have successfully controlled domiciliated vectors in many regions. Non-domiciliated vectors remain responsible for a significant transmission risk, and their control is a challenge. We performed a proof-of-concept field trial to test alternative strategies in rural Yucatan, Mexico. Follow-up of house infestation for two seasons following the interventions confirmed that insecticide spraying should b… Show more

“…New vector control strategies must be tested, for instance, in regions were T. infestans is only found as adult forms inside houses. The long-lasting impregnated curtains or mosquito mesh strategy proposed by Ferral et al (2010) for non-domiciled Triatoma dimidiata might be a good alternative. The susceptibility of Chilean triatomines to pathogens should be tested to provide a biological mechanism of control that specifically targets the species of interest, maybe even in its sylvatic habitat.…”

“…Indeed, it is now well established that the efficacy of conventional insecticide spraying is short-lived in the case of non-domiciliated triatomines seasonally infesting houses. [28][29][30][31] Previous control efforts in Veracruz indicated that three insecticide applications 8 months apart were required to reduce T. dimidiata infestation, 32 but there was no follow-up to assess potential re-infestation after interrupting control interventions. Re-infestation by T. dimidiata following insecticide spraying has been frequently observed in the Yucatan peninsula, Mexico, 28,31 as well as in Guatemala.…”

“…Thus, the control of such non-domiciliated or autochthonous triatomines remains a major problem for vector control , and novel approaches such as screens, bednets and house improvements will be necessary to interrupt transmission (Figure 4) (Monroy et al, 1998(Monroy et al, , 2009Barbu et al, 2009Barbu et al, , 2011Ferral et al, 2010).…”
