Abstract: The follicular development of Culex tritaeniorhynchus summorosus females after taking various amounts of blood was observed, and the following facts were demonstrated. Even in the females which have taken merely a trace amount of blood insufficient for filling up the midgut, many follicles do initiate the development, but none of them mature. When the uptake amount of blood increases, some follicles develope to mature eggs, and generally the more amount of blood is taken, the more mature eggs are produced; those follicles which have initiated the development but have failed to mature are degenerated. The females which have smaller number of mature eggs than the normal will lay a small egg raft or will take a second blood meal, depending on which is given the oviposition place or the blood source. / 種々の量の血液を摂取したコガタアカイエカ雌成虫の濾胞の発育について調べた結果次の点が明らかとなった.中腸を満たすに足りないほど少量しか吸血しなかった雌でも,多くの濾胞が発育を始めるが,成熟卵にまで発育する濾胞はない。吸血量が増えると成熟卵まで発育する濾胞が出現し,その数は.吸血量が増えるほど多くなる.その場合に,成熟卵にならない濾胞は発育途中から退化する.少数の卵しか持たない雌は,産卵場所を与えると,きわめて小さな卵塊を産卵するが,産卵場所を与えずに吸血源のみを与えると抱卵したまま再吸血する.
