We focused on the analysis of biological parameters of two different abundant populations of Dipetalogaster maximus (Uhler) (Hemiptera: Reduviidae: Triatominae) from northwestern Mexico. The biological parameters were related to hatching of eggs, life cycle, and meal needed for molting by each instar of two populations from environmentally similar areas (El Fandango and San Dionisio) with a similar number of available hosts as blood meal sources. The D. maximus populations from the two locations were evaluated and compared. No significant differences (P>0.05) were recorded for the average hatching time of the two cohorts. The median egg‐to‐adult development time and the number of blood meals at each nymphal group were significantly shorter (P<0.05) for the El Fandango cohort. The number of obtained females at the end of the cycles, number of eggs laid, and rate of egg hatching were significantly higher (P<0.05) for the El Fandango cohort. These results contribute to the estimation of abundances of the studied populations of D. maximus in areas where many tourists go for camping and have an increased risk of being bitten and infected by this species.

墨西哥西北部两个最大的Dipetalogaster maximus种群的生活史（Uhle​​r，1894）（半翅目：Reduviidae：Triatominae）。

我们专注于分析墨西哥西北部两个不同的最大双足龙（Upeter）（半翅目：Reduviidae：Triatominae）的生物学参数。生物学参数与环境相似区域（El Fandango和San Dionisio）的两个种群的每只幼虫蜕皮所需的卵的孵化，生命周期和进食所需的膳食有关，这些宿主的可用宿主数量也与血粉来源相似。该D.鲆对两个地点的人口进行了评估和比较。两个队列的平均孵化时间没有显着差异（P> 0.05）。El Fandango队列中每个成虫组的卵到成人发育时间中位数和血粉数量显着缩短（P <0.05）。在El Fandango队列中，在周期结束时获得的雌性数量，产卵数和卵孵化率均显着更高（P <0.05）。这些结果有助于估计许多旅游者露营的地区最大被捕食的D. maximus种群的数量，并且被该物种咬住和感染的风险增加。
