Resumo
Background: Meccus pallidipennis (Hemiptera: Reduviidae) is only found in Mexico and is one of the most important
vectors for Trypanosoma cruzi transmission there. Because data concerning the ability of this bug to adapt to different
environments are scarce, we aimed to elucidate its biology, behavior and ability to acclimatize to different environ mental conditions.
Methods: From the eclosion of 90 1st instar nymphs, development was followed until the adult phase. Adults were
fed after 30 days of fasting, and the average amount of blood ingested, the time between the beginning of the blood
meal and the production of feces, and the frequency of stools/insect were recorded during their meals. After taking a
blood meal, couples were isolated and monitored for 21 days, during which eggs were collected weekly.
Results: The development of M. pallidipennis took 171.74±7.03 days to complete its life cycle, and females ingested
larger amounts of blood than males. Oviposition was constant and did not demonstrate a significant decrease during
this study.
Conclusion: Meccus pallidipennis was able to acclimatize to fluctuating laboratorial conditions other than those nat urally found in Mexico.
