The effect of several human blood fractions artificially fed to Rhodnius prolixus Stal 1859 on oviposture (fecundity), egg-hatching (fertility) and life cycle was observed. Specimens fed on man's blood were more fecund than those fed with woman's blood. There were no significant differences in fertility related to host sex. The nymphal development time and number of feedings to molt to the following instar were estimated. Animals fed only on blood plasm did not finish nymphal development, while those fed only blood red cells ended their life cycle in the third nymphal instar. Total life cycle lasts 129 days in individuals fed with whole blood.
观察了将几种人工喂养给1859年的红带锥蝽（Rhodnius prolixus Stal）的人血成分对产卵（繁殖力）、卵孵化（受精率）和生命周期的影响。以男性血液为食的标本比以女性血液为食的标本繁殖力更强。与宿主性别相关的受精率没有显著差异。估计了若虫发育时间和蜕皮到下一龄期所需的取食次数。仅以血浆为食的动物没有完成若虫发育，而仅以红细胞为食的动物在第三龄若虫期结束生命周期。用全血喂养的个体的总生命周期为129天。
