The reproductive success of Aedes aegypti, a primary vector of dengue and other arboviruses, depends on host blood nutrition. Variations in blood group composition may significantly influence mosquito fecundity, egg viability, and offspring fitness, potentially impacting disease transmission dynamics. This study investigates the effect of human blood groups on the egg hatching rate and offspring morphometric development of Aedes aegypti.
Blood groups B and O demonstrated the highest fecundity rates, with significantly larger egg sizes and greater egg viability compared to other groups (P < 0.05). Offspring from these groups exhibited superior morphometric traits, including longer larval lengths and larger head capsule widths. In contrast, blood groups B and AB resulted in the lowest reproductive success, with smaller egg sizes and reduced larval fitness. The observed differences suggest blood group-specific variations in nutritional quality influencing mosquito reproductive potential and offspring development. The findings reveal that host blood group significantly impacts Aedes aegypti reproduction and larval fitness, with B and O blood groups providing the most favorable outcomes.
埃及伊蚊是登革热和其他虫媒病毒的主要传播媒介，其繁殖成功取决于宿主血液营养。血型组成的变化可能会显著影响蚊子的繁殖力、卵的活力和后代的健康状况，从而可能影响疾病传播动态。本研究调查了人类血型对埃及伊蚊卵孵化率和后代形态发育的影响。
B型血和O型血的繁殖率最高，与其他血型相比，卵的大小显著更大，卵的活力更强（P < 0.05）。这些血型的后代表现出更优的形态特征，包括更长的幼虫长度和更大的头壳宽度。相比之下，B型血和AB型血的繁殖成功率最低，卵的大小较小，幼虫健康状况较差。观察到的差异表明，营养质量存在血型特异性差异，影响蚊子的繁殖潜力和后代发育。研究结果表明，宿主血型对埃及伊蚊的繁殖和幼虫健康状况有显著影响，B型血和O型血的效果最为理想。
