Infection with the rodent malarial parasite Plasmodium yoelii nigeriensis caused a significant reduction in the reproductive fitness (number of eggs produced and proportion of eggs hatched) of two different generations of Anopheles stephensi. Overall fertility (number of larvae produced) was reduced by 38.3% in the generation containing smaller mosquitoes (with a wing length of 3.2 +/- 0.1 mm) with relatively larger parasite burdens, and by 48.81% in the generation containing larger mosquitoes (with a wing length of 3.4 +/- 0.1 mm). The contribution that reduction in egg production and egg hatching made to overall reduction in reproductive fitness differed in each experiment. No significant difference was observed in the egg size (length from tip to tip and breadth at the centre) of control and infected mosquitoes in another generation of infected An. stephensi.
感染啮齿动物疟原虫约氏疟原虫尼日尔株会导致两代不同的斯氏按蚊的生殖适合度（产卵数量及孵化的卵的比例）显著降低。在含有寄生虫负荷相对较大的较小蚊子（翅长3.2±0.1毫米）的一代中，总体繁殖力（产生的幼虫数量）降低了38.3%，而在含有较大蚊子（翅长3.4±0.1毫米）的一代中降低了48.81%。每次实验中，产卵量和孵化率的降低对生殖适合度总体降低的贡献有所不同。在另一代受感染的斯氏按蚊中，未观察到对照蚊子和受感染蚊子的卵大小（从尖端到尖端的长度以及中心处的宽度）有显著差异。
