A cohort of 100 eggs of Triatoma mazzottii Usinger was studied to obtain information on its life cycle. Egg incubation took 24 days; mean duration of 1st, 2nd, 3rd, 4th, and 5th instar nymphs was 27, 36, 39, 46, and 64 days respectively; mean time from egg to adult was 236 days. The total duration of the nymphal stages was 212 days. The total nymph mortality in cohort was 16.3%, and the embryonic egg mortality was 14.0%. The greater mortality occurred in the 2nd instar. The average number of eggs/female/week was 9.8 during 15 weeks of observation. Of the total eggs laid (2,514), only 58.7% hatched. The total of insects that achieved the adult stage (72), 38 were females (52.8%), and 34 were males (47.2%). The influence of age and feeding on the first mating of T. mazzottii were also studied. It was found that the first mating depended on the male's age and it was on the average 30 days after the last imaginal molt. The female could be mating since 2nd days after the imaginal life. The nutritional status did not play an important role in the capacity of the insect for the first mating.
对100枚马佐蒂红猎蝽（Triatoma mazzottii Usinger）的卵进行了一组研究，以获取其生命周期的相关信息。卵孵化需要24天；1龄、2龄、3龄、4龄和5龄若虫的平均持续时间分别为27天、36天、39天、46天和64天；从卵到成虫的平均时间为236天。若虫阶段的总持续时间为212天。该组若虫的总死亡率为16.3%，胚胎期卵的死亡率为14.0%。2龄若虫期死亡率更高。在15周的观察期内，每只雌虫每周平均产卵数为9.8枚。在产下的所有卵（2514枚）中，只有58.7%孵化。发育到成虫阶段的昆虫总数为72只，其中38只为雌虫（52.8%），34只为雄虫（47.2%）。还研究了年龄和取食对马佐蒂红猎蝽首次交配的影响。结果发现，首次交配取决于雄虫的年龄，平均在最后一次成虫蜕皮后30天。雌虫在成虫期生活2天后即可交配。营养状况在昆虫首次交配的能力方面并未发挥重要作用。
