Contrastingly, we show here that during the reproductive response of Soay sheep exposed to summer day lengths, the reverse applies: Melatonin acts directly on anterior-pituitary cells, and these then relay the photoperiodic message back into the hypothalamus to control neuroendocrine output.

比较而言，我们在这里说明，在暴露于夏季日照长度的索艾羊生殖反应期间，反向应用：褪黑激素直接作用于垂体前叶细胞，然后这些细胞把光周期信息返回下丘脑控制神经内分泌输出。

The diapause rate induced under differenteshort-light decreases with increasing temperature at＞20℃,and decreases underdifferent long-daylengths with increasing temperature distinctly at＞22℃;For SDT, the diapause rate is 69.23%～90.91% at 28℃.But its photoperiodic responses curve isanomalous wavilness at 30℃,showing the photoperiodic responses didn\'t occured.

温度在大猿叶甲的滞育诱导中起决定性作用：无论光周期如何，当温度≤18℃时，龙南种群成虫均进入滞育；修水种群在温度≤20℃时，成虫均进入滞育；山东泰安种群在温度＜25℃时，全部个体进入滞育；哈尔滨种群在温度≤28℃时，全部个体进入滞育。

Photoperiodic counter is an important part of photoperiodic response. It accumulates and stores photoperiodic information contained in a sequence of light-dark cycles.
