title: Update on the biology of Triatoma dimidiata Latreille (Hemiptera: Reduviidae) under laboratory conditions.
abstract: Feeding time, postfeeding defecation delay, and life cycle for each stage of a cohort of recently colonized Mexican Triatoma dimidiata were evaluated, and results were compared to existing published information on this species. Seventy-five nymphs (41.7%) completed a cycle with an average time from N-I to adult of 142 +/- 64 days. The average span in days for each stage was 20.2 for N-I, 17.9 for N-II, 10.1 for N-III, 43.6 for N-IV, and 55.1 for N-V. First-stage nymphs had the highest mean feeding time (25 min) and the longest postfeeding defecation delay (45 min). Differences among biological data from previous studies and the present study confirm the importance of conducting research on the behavior of the indigenous triatomine species from various countries.
