通过淡色库蚊卵泡发育和滞育相对照,观察到滞育指标为第一卵泡停滞在羽化后24个时、长约50μm的N期,同时可用原卵区(第二卵泡加第三卵泡)和第一卵泡几乎等长作为滞育的佐证。进入Ⅰ_a期开始均属发育蚊。Ⅰ_a期是卵泡早期发育的最旺盛时期,并开始吸血,在不供血情况下,可继续发育直至停留在Ⅱ_b休止期。 通过蚊虫去首替代脑抑制咽侧体分泌保幼激素的方法,与滞育蚊对照。推论卵泡滞育与缺乏保幼激素有关;第一卵泡从羽化时的No.1期发育增至N期,似乎与保幼激素无关,但从N期进一步发育则依赖咽侧体分泌保幼激素的作用,咽侧体释放保幼激素的临界时间约在雌蚊羽化后24小时左右。
Through the follicular development and diapause control of Culex pipiens pallens, the diapause index was observed as the first follicle stagnating at 24 days after eclosion, with a length of about 50μm and the original oocyte (the second follicle plus the third follicle) Almost as long as the first follicle and as evidence of diapause. Into Ⅰ_a period are beginning to develop mosquitoes. Ⅰ_a period is the most vigorous development of early follicular follicles, and began to suck blood, without blood supply, can continue to develop until staying in Ⅱ b rest period. Mosquitoes go to the head to replace the brain inhibition of pharyngeal secretion of juvenile hormone method, and diapause mosquito control. Inferred follicular diapause and lack of juvenile hormone related to the first follicle from the emergence of the first phase of development to N, seems to have nothing to do with juvenile hormone, but further development from N is dependent on the pharyngeal side of the secretion of juvenile hormone The role of the pharyngeal side of the release of juvenile hormone critical time about female mosquitoes after about 24 hours.
