摘要:

用高效液相色谱法(HPLC)测定了鞭角华扁叶蜂(Chinolyda flagellicornis)末龄幼虫及滞育预蛹血淋巴中保幼激素 Ⅲ(JHⅢ)的滴度。结果表明,末龄幼虫血淋巴中JHⅢ的滴度虽呈明显下降趋势,但仍保持较高的水平(17ng·mL-1) ;滞育预蛹血淋巴中JHⅢ的滴度达20ng·mL-1 左右,而在化蛹前一天则可达30ng·mL-1 以上。表明JH对鞭角华扁叶蜂预蛹滞育起调节作用。

Abstract:

The titres of haemolymph juvenile hormone(JHⅢ) of the last instar and diapausing prepupa of the sawfly Chinolyda flagellicornis were determined by high performance liquid chromatography(HPLC). In the last instar, the titres of JHⅢ dropped sharply, but still maintained in mid titres(about 17 ng·mL-1). The titres of JHⅢ of diapausing prepupa maintained in a higher level(about 20 ng·mL-1), and over 30 ng·mL-1 in the day before pupation. It seemed that the diapause of Chinolyda flagellicornis was regulated by JH.
