Anopheles stephensi mosquitoes which had fed upon mice infected with Plasmodium yoelii nigeriensis malaria parasites produced significantly fewer eggs than mosquitoes fed on an uninfected mouse. Fecundity reduction was more pronounced when the bloodmeal contained malaria gametocytes and the mosquitoes developed oocysts. Egg production and haematin excretion were correlated for uninfected bloodfed mosquitoes; the presence of P.y.nigeriensis in the blood affected this relationship. Reduced fecundity was associated with a significant reduction of bloodmeal size (measured by haematin excretion) in mosquitoes which ingested gametocytaemic blood. The bloodmeal size in mosquitoes fed on parasitaemic blood without gametocytes was not significantly reduced. The use of haematin assays for determination of bloodmeal size in mosquitoes is discussed.
吸食感染了约氏疟原虫尼日利亚株疟原虫的小鼠血液的斯氏按蚊所产的卵明显少于吸食未感染小鼠血液的蚊子。当血餐中含有疟原虫配子体且蚊子形成卵囊时,繁殖力降低更为明显。未感染的吸血蚊子的产卵量和血红素排泄量相关;血液中存在约氏疟原虫尼日利亚株影响了这种关系。繁殖力降低与摄入含有配子体血液的蚊子血餐大小(通过血红素排泄量衡量)显著减少有关。吸食不含配子体的患寄生虫血症血液的蚊子的血餐大小没有显著减少。文中讨论了使用血红素测定法来确定蚊子血餐大小的问题。
