| sampling rhodnius neglectus in mauritia flexuosa palm trees: a field study in the brazilian savanna. | two sampling methods (manual capture and live-baited adhesive traps) were compared for collecting the bug rhodnius neglectus lent (hemiptera: reduviidae: triatominae) from palm trees, mauritia flexuosa l. (arecaceae), in the savanna of brasília df. r. neglectus was found in 19/50 (38%) of palm trees sampled. the detection rate was much higher by visual inspection and manual capture (18/50=36%) than by our trapping method (5/50=10%), although one tree was found to be positive by trapping but not ... | 2003 | 12941022 |
| enzootic transmission of trypanosoma cruzi and t. rangeli in the federal district of brazil. | the federal district of brazil (df) lies within the cerrado biome, where open shrubland (savannas) is interspersed with riverside gallery forests and permanent swamps (veredas). trypanosoma cruzi-infected native triatomines occur in the area, but the enzootic transmission of trypanosomatids remains poorly characterized. a parasitological survey involving sylvatic triatomines (166 rhodnius neglectus collected from mauritia flexuosa palms) and small mammals (98 marsupials and 70 rodents, totaling ... | 2004 | 15654478 |
| [spatial distribution of triatominae populations (hemiptera: reduviidae) in mauritia flexuosa palm trees in federal district of brazil]. | to determine and analyze the distribution of triatominae sylvatic populations in the federal district of brazil, 150 mauritia flexuosa palm trees were sampled in six veredas of different landscapes (sylvatic, rural and peri-urban) in the rainy season. triatomines were morphologically identified and grouped by sex and nymphal stage and were examined to verify infection by trypanosoma cruzi and trypanosoma rangeli. twenty eight (18.6%) palm trees were infested by rhodnius neglectus and fourteen (9 ... | 2004 | 15330065 |
