| beauveria bassiana (hyphomycetes) as a possible agent for biological control of chagas disease vectors. | beauveria bassiana (balsamo) vuillemin (isolate cg306) was tested on 3rd instars of 9 triatoma spp., 4 rhodnius spp., 2 panstrongylus spp. and dipetalogaster maxima (uhler) at 25 degrees c and 50% rh. quantitative sporulation of the fungus on cadavers was studied at 25 degrees c and 97% rh. mortality, estimates of survival time, and conidial production on cadavers differed significantly among the genera and species tested. panstrongylus herreri wygodzinsky, dipetalogaster maxima, triatoma pictur ... | 1998 | 9835689 |
| sylvatic triatominae of the phyllosoma complex (hemiptera: reduviidae) around the community of carrillo puerto, nayarit, mexico. | research on domestic and sylvatic triatomines within the community of carrillo puerto and neighboring areas of nayarit, mexico, documented that triatoma longipennis (usinger) and triatoma picturata (usinger) were infected with trypanosoma cruzi (l.) in both habitats. t. picturata was the predominant species in both habitats. mouse baited-traps increased the effectiveness of collecting sylvatic triatomines, which were difficult to sample by inspecting habitats such as burrows, caves, and cliffs. ... | 2001 | 11580035 |
| preliminary results of random amplification of polymorphic dna among triatominae of the phyllosoma complex (hemiptera, reduviidae). | in mexico, triatoma longipennis (usinger), triatoma picturata (usinger), and triatoma pallidipennis (stal), primary chagas disease vector species of the phyllosoma complex, were analyzed by randomly amplified polymorphic dna (rapd). sixteen decametric primers resolved individual profiles not identical, but partially discriminative between species. analysis based on pairwise presence/absence comparisons between the three species was performed using three primers and two outgroup species triatoma ... | 2003 | 15049086 |
| colonization of rock pile boundary walls in fields by sylvatic triatomines (hemiptera: reduviidae) in jalisco state, mexico. | granite rocks is a very abundant material in mexico because they are used habitually as borders for fields. the current work established the significance of this ecotype as a colonization site for triatomines of the phyllosoma complex. seven sites, arbitrary selected, in san martin de hidalgo municipality (mexico) were investigated in april 2002 by using 210 mouse bait-traps left during the night in wall hollows. one hundred and seventy-two triatomines of all life stages were collected from the ... | 2004 | 15185954 |
| natural crossbreeding between sympatric species of the phyllosoma complex (insecta: hemiptera: reduviidae) indicate the existence of only one species with morphologic and genetic variations. | the nucleotide sequences of the cytochrome b gene and the antennal phenotypes were analyzed for the following triatomine species: triatoma longipennis, triatoma pallidipennis, and triatoma picturata, which belong to the phyllosoma complex. these species inhabit sympatric areas from talpa de allende, autlan de navarro, and teocuitatlan de corona in jalisco, mexico. molecular marker analysis showed that the sympatric individuals are the natural crossbred descendents of different individuals living ... | 2010 | 20064999 |
