Trapping Triatominae in silvatic habitats.
Large-scale trials of a trapping system designed to collect silvatic Triatominae are reported. Live-baited adhesive traps were tested in various ecosystems and different triatomine habitats (arboreal and terrestrial). The trials were always successful, with a rate of positive habitats generally over 20% and reaching 48.4% for palm trees of the Amazon basin. Eleven species of Triatominae belongi...

. infection below which mass peatment will become unfavourable in terrns of cost-effectiveness. However, it also implies that above this value variations in the prevalence of infection have little effect on the cost per infected person treated. The precise prevalence value at which this non-linearity is evident is dependent on the cost per person treated: the higher this cost, the lower the pre...
متن کاملChanges in the sexual dimorphism of triatominae in the transition from natural to artificial habitats.
A shift from large to small average sizes was observed in Triatoma infestans and Rhodnius domesticus between field and domestic (or laboratory) conditions of life. It was more pronounced in the female specimens, leading to a subsequent reduction of sexual size dimorphism. This feature is discussed in terms of genetic and populational changes occurring from natural to artificial habitats, in par...
متن کاملThe process of domestication in Triatominae.
The Triatominae represent a subfamily of the Reduviidae defined on the basis of their bloodsucking habit and associated characteristics. At present, 128 species are formally recognised, grouped into 17 genera in 5 tribes. The majority are silvatic, associated with a wide variety of vertebrate hosts – particularly nest-building mammals and birds. Others occupy silvatic and peridomestic habitats ...
متن کاملSome considerations about the ecology of Triatominae.
Observations on the ecology of silvatic Triatominae are still fragmentary, principally because target species in control process are almost exclusively domestic. Report of silvatic species invading human dwellings must lead research to be focused on their original ecology, in order to assist in understanding their process of domestication and devising strategies for surveillance.
