红细胞消化的两种一般模式观察到的代表性物种从四个昆虫目。摄入的红细胞迅速溶血，血粉在体虱（Pediculus humanusL）中保持液化。以及蚤Ctenocephalides felis（Bouché）和Xenopyslla cheopis（Rothschild）。围食膜缺失。相反，臭虫（Cimex lectulariusL.）的血粉中的红细胞在大量降解之前有6-18小时的滞后时间。沙蝇（Phlebotomus papatasiScopoli）、斯氏按蚊（Anopheles stephensisListon）和尖音库蚊（Culex pipiens L.）沙蝇和蚊取食后18-24 h，血粉凝结，被围食膜包裹。在臭虫中，凝血和围食膜不太明显。提出病原体类型的获得和维持（即，原核生物对真核生物）受到血粉加工的一般模式的限制。
Two general patterns of erythrocyte digestion were observed in representative species from four insect orders. Ingested erythrocytes were hemolyzed rapidly, and blood meals remained liquefied within body lice,Pediculus humanusL. and the fleasCtenocephalides felis(Bouché) andXenopyslla cheopis(Rothschild). Peritrophic membrane was absent. In contrast, there was a lag time of 6–18 h before substantial degradation of erythrocytes within the blood meals of bed bugs,Cimex lectulariusL.; the sand flyPhlebotomus papatasiScopoli; and the mosquitoesAnopheles stephensiListon andCulex pipiensL. Blood meals of sand flies and mosquitoes were clotted and surrounded by peritrophic membrane at 18–24 h after feeding. Clotting and peritrophic membrane were less pronounced in bed bugs. It is proposed that acquisition and maintenance of pathogen types (i.e., prokaryotic versus eukaryotic) within insects are constrained by the general pattern of bloodmeal processing.
