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.
对一群新定植的墨西哥二斑锥蝽每个阶段的进食时间、进食后排便延迟和生命周期进行了评估，并将结果与该物种已发表的现有信息进行了比较。75只若虫（41.7%）完成了一个周期，从一龄若虫到成虫的平均时间为142±64天。每个阶段的平均天数跨度为：一龄若虫20.2天，二龄若虫17.9天，三龄若虫10.1天，四龄若虫43.6天，五龄若虫55.1天。一龄若虫的平均进食时间最长（25分钟），进食后排便延迟最长（45分钟）。先前研究和本研究的生物学数据差异证实了对各国本土锥蝽物种行为进行研究的重要性。
