Environmental management for the control of Triatoma dimidiata (Latreille, 1811), (Hemiptera: Reduviidae) in Costa Rica: a pilot project

House improvements and community participation in the control of Triatoma dimidiata re-infestation in Jutiapa, Guatemala

“…In addition, changes to their houses influenced the inhabitants' perceptions and feelings towards their way of living and some female householders began to improve their dirt floors, without influence from the researchers. This was in contrast to the results obtained in Costa Rica, where house improvements were achieved through environmental management, but researchers were responsible for carrying out the changes 12 .…”

“…Reinfestation of houses could be caused by residual populations that are not affected by the insecticides or by insect dispersion from other foci that could include the peridomicile and sylvatic environments or neighboring villages 2,12 . This is supported by genetic studies that have shown that populations from adjacent villages are panmictic 13 and by direct observations of flying or walking bugs made in northern Guatemala 4 .…”

Comparative Field Trial of Alternative Vector Control Strategies for Non-Domiciliated Triatoma dimidiata

“…This seems less effective than a peridomestic ecological control intervention in Costa Rica, which resulted in a strong reduction in house infestation over a 1-year period. 34 The lower efficacy we observed may be explained by a direct influx of sylvatic bugs into the houses, independent from peridomestic populations. Indeed, population genetics analysis indicated that house infestation was caused by an influx of both peridomestic and sylvatic insects, although the relative contribution of each source remained unclear.…”

Conocimientos y factores de riesgo relacionados con la enfermedad de Chagas en dos comunidades panameñas donde Rhodnius pallescens es el vector principal

“…Aun cuando R. pallescens no coloniza con frecuencia estructuras asociadas al ambiente doméstico (3), promover el mejoramiento sanitario de estas áreas podría reducir la presencia y posterior movilización de chinches vectores hacia el interior de las casas. Esta práctica ha sido descrita como medida de control para T. dimidiata (22).…”
