| triatoma ryckmani (hemiptera: reduviidae) in the epiphyte tillandsia xerographica (bromeliaceae) in the semiarid region of guatemala. | for the first time, the reduviid bug triatoma ryckmani zeledón and ponce (hemiptera; reduviidae) was recorded to inhabit the epiphyte tillandsia xerographica rohweder (bromeliaceae) in the semiarid region of guatemala. these bromeliads grow mainly in drought-resistant trees with rough bark such as pereskia lychnidiflora (cactaceae). in our study site, we investigated 30 t. xerographica, and 53 specimens of t. ryckmani were found. most t. ryckmani (68.5%) were unfed. ants (formicidae) were the pr ... | 2004 | 15185931 |
| dispersion and colonization of triatoma ryckmani (hemiptera: reduviidae) in artificial environments in a semiarid region of a chagas disease endemic area in guatemala. | the colonization capacity and dispersal of sylvatic populations of triatoma ryckmani zeledón and ponce were investigated by means of experimental chicken coops installed within the semiarid region in the department of el progreso, guatemala. in the four artificial habitats a total of 672 t. ryckmani was found as well as two males of t. dimidiata (latreille). triatomine densities were not the same in the four chicken coops. from one chicken coop 53.4% (359) of the triatomines were collected. full ... | 2004 | 15234663 |

| a mass collection of triatoma ryckmani (hemiptera: reduviidae) from stenocereus eichlamii (cactaceae) in the semiarid region of guatemala. | a population of 216 specimens of stenocereus eichlamii (cactaceae, subfamily cereoideae) was surveyed for triatoma ryckmani (vector of chagas disease) in a one hectare plot of semiarid habitat in guatemala. out of 44 plants that had dead and dry sections, 24 plants had a total of 103 specimens of t. ryckmani. in comparison with other areas of guatemala, t ryckmani is well established in the semiarid ecosystem (infestation index 54.5, density = 2.3 and crowding index 4.3). the insects were mainly ... | 2004 | 17354404 |
