| differences in saliva composition among three brazilian populations of panstrongylus megistus (hemiptera, reduviidae). | comparisons of electrophoretic profiles of triatomines (panstrongylus megistus) from the brazilian states of bahia (ba), minas gerais (mg) and santa catarina (sc) revealed differences in the composition of the saliva between the three populations. a phenogram constructed on the basis of the most representative electrophoretic banding patterns allowed the specimens tested to be divided into two groups. the ba and sc populations could be completely separated while some individuals from mg could be ... | 1999 | 9924964 |
| interpopulation variability among panstrongylus megistus (hemiptera: reduviidae) from brazil. | comparisons were made among panstrongylus megistus (burmeister) from three areas of brazil (bahia, minas gerais, and santa catarina), where populations differ with regard to their degree of association with human dwellings. the following characters were studied: morphology of the eggs and the male genitalia; morphometry of the head and thorax; isoenzyme profile; enzymatic activity of the alpha-glycerophosphate dehydrogenase (alpha-gpdh); and cytogenetics. in general, differences were observed in ... | 2003 | 14680104 |
| biogeography of brazilian populations of panstrongylus megistus (hemiptera, reduviidae, triatominae) based on molecular marker and paleo-vegetational data. | in epidemiological terms, panstrongylus megistus is one of the most important species of triatomine bug in brazil. samples from 11 localities were studied using the random amplification of polymorphic dna (rapd) technique, which was able to differentiate the study populations clearly. biogeographical data indicate that these populations could already have arisen 18,000 years ago (c(14)), it being possible to differentiate insects from the brazilian states of santa catarina (sc) in the south, cea ... | 2006 | 17055993 |
| [colonization by panstrongylus megistus (hemiptera, reduviidae, triatominae) inside homes in são josé do cerrito, sc: first report]. | in response to complaints of the presence of triatomines in a fishing hut on the banks of the caveiras river, in the municipality of são josé do cerrito, state of santa catarina, an investigation was conducted in this hut and in other ecotopes neighboring the initial finding. fifteen specimens of panstrongylus megistus were found and none of them were infected. the locality of this ecotope is visited occasionally by capybaras, opossums, armadillos and rats. | 2008 | 18853021 |
