In a period of fourteen months (April 2000 May 2001), the development of the presence of Triatoma dimidiata in artificial ecotopes consisting of six experimental chicken coops installed in the forest of the Yaxha' archaeological site, Melchor de Meneos, Petén, was studied, of which . three were located in primary forest and three in disturbed or guamil forest. A total of 41 insects were found in the six chicken coops, most of them (83%) remained less than a month in the chicken coop in which they were found, which indicates a high active dispersal capacity by the populations. wild of this species. Seasonality in dispersal was detected: adults only disperse in warm months; the nymphs do it all year round, but in greater abundance in the rainy months.
The insects did not colonize the chicken coops (simultaneous presence of adults, nymphs and eggs), which could be due to varied preferences for shelter, food sources and the search for mates or spawning sites.
The main contribution of the study was to confirm that the nymphs are capable of active mobility and that the adults disperse in the warm months. Due to this, it is recommended that the control sprayings against the pointed bug be carried out in the months of February to June, since this would eliminate the adults and the residual insecticide would affect the first-stay nymphs that would hatch from the eggs deposited by the insect. adults, thus preventing a new generation of bedbugs.
