The ovaries of the mosquito Aedes aegypti cultured in vitro secrete material that behaves like ecdysone in a radioimmunoassay. The material was identified as alpha-ecdysone by high-resolution liquid and gas-liquid chromatography. Secretion reached a maximum 16 hr after a blood meal as shown by bioassay and direct determination. Ovariectomy reduced the concentration of ecdysone in the adult after a blood meal. Qualitative analysis of whole-body extracts indicated beta-ecdysone to be the principal species present. Thus the ovaries appear to secrete a prohormone, alpha-ecdysone, which is converted to beta-ecdysone. Beta-ecdysone plays a significant role in stimulating egg development in the adult mosquito and may have reproductive roles in other insects.
在体外培养的埃及伊蚊卵巢分泌的物质,在放射免疫分析中表现得像蜕皮激素。通过高分辨率液相色谱和气相色谱法,该物质被鉴定为α-蜕皮激素。生物测定和直接测定表明,吸血后16小时分泌量达到最大值。卵巢切除降低了吸血后成虫体内蜕皮激素的浓度。对全身提取物的定性分析表明,β-蜕皮激素是主要存在的种类。因此,卵巢似乎分泌一种前体激素α-蜕皮激素,它会转化为β-蜕皮激素。β-蜕皮激素在刺激成年蚊子卵子发育中起重要作用,并且可能在其他昆虫中具有生殖作用。
