Normal and infected Culex females were fed 11 different amino acids. These substances were labeled with tritium and each was given separately in glucose solution. After the uptake the marker appears first in crop, cardia and midgut. Later on the other tissues get labeled more or less. It seems that the labeling follows a characteristic pattern for each amino acid. Essential amino acids are taken up intensively; for example leucine not only in the midgut epithelium but also in the ovary and the fat body. There is nearly no uptake of the non-essential amino acids alanine, glutamic acid and DOPA by the tissues of both groups of females. These amino acids are only seen in the midgut area and not in the other tissues. In infected mosquitos the uptake of the essential acid, phenylalanine, corresponds only to that of a non-essential amino acid.
正常和受感染的库蚊雌蚊被喂食了11种不同的氨基酸。这些物质用氚标记，每种都单独溶解在葡萄糖溶液中喂食。摄取后，标记物首先出现在嗉囊、贲门和中肠。后来其他组织或多或少也被标记。似乎每种氨基酸的标记都遵循一种特征模式。必需氨基酸被大量摄取；例如亮氨酸不仅在中肠上皮细胞中，而且在卵巢和脂肪体中也有摄取。两组雌蚊的组织几乎都不摄取非必需氨基酸丙氨酸、谷氨酸和多巴。这些氨基酸只出现在中肠区域，而不在其他组织中。在受感染的蚊子中，必需氨基酸苯丙氨酸的摄取量仅相当于一种非必需氨基酸的摄取量。
