The duration of the gonotrophic cycle and survivorship of Anopheles vestitipennis Dyar & Knab was estimated in 2 malarious areas of Chiapas, Mexico: the Lacandon Forest and the Pacific Ocean Coastal Plain. Blood-engorged females held in an outdoor cage required 2.75 d for egg maturation, and 3.75 d for the duration of the gonotrophic cycle. Duration of the gonotrophic cycle also was estimated by parous-nulliparous dynamics for 20 consecutive days and autocorrelation time-series analysis, and by mark-recapture techniques. These methods depicted differences between the Lacandon Forest (3-d cycle) and the Coastal Plain (2-3 d cycles). Daily survival rates were estimated vertically and were generally higher in the Lacandon Forest (0.68) than in the Coastal Plain (0.45-0.58). The probability of mosquitoes surviving the sporogonic cycle was 10-100 times greater in the Lacandon Forest. The pregravid rate was 8.2%, and 29.3% of females with primary follicles beyond Christophers' stage III had traces of red blood in the gut. The 1st statistic indicated that 8.2% of females required > 1 blood meal for initial egg development, the 2nd statistic indicated that 29.3% of females take > 1 blood meal during a gonotrophic cycle. In summary, the enhanced vectorial role of this species is explained partially by high longevity and multiple blood-feeding habits.
拉坎顿森林和太平洋沿岸平原，对饰跗按蚊的生殖营养周期持续时间和存活率进行了估算。关在户外笼子里的饱血雌蚊卵成熟需要2.75天，生殖营养周期持续3.75天。生殖营养周期的持续时间还通过连续20天的经产-未产动态和自相关时间序列分析以及标记重捕技术进行了估算。这些方法揭示了拉坎顿森林（3天周期）和沿海平原（2 - 3天周期）之间的差异。垂直估算每日存活率，拉坎顿森林的存活率通常（0.68）高于沿海平原（0.45 - 0.58）。蚊子在孢子生殖周期存活的概率在拉坎顿森林中要高10 - 100倍。怀孕前期比率为8.2%，处于克里斯托弗斯三期以上初级卵泡的雌蚊中，29.3%的肠道内有残留的红细胞痕迹。第一个统计数据表明，8.2%的雌蚊初始产卵发育需要不止一次血餐，第二个统计数据表明，29.3%的雌蚊在一个生殖营养周期内会吸食不止一次血餐。总之，该物种增强的媒介作用部分归因于其较长的寿命和多次吸血习性。
