家蚕蛾交配与产卵速度的研究

为探索长交促进产卵速度加快的原因,经多次试验表明:在设区范围内,交配时间越长或交配时刻越晚,产卵速度有越快的倾向。延长交配时间与延迟交配时刻之所以表现出产卵度加快的现象其实质是延迟了拆对时刻,因而在单位时间内产卵集中,原因是拆对延迟促进了卵的成熟(内因)且接近适于产卵的黄昏时分(外因)。

STUDIES ON COPULATION DURATION AND OVIPOSITION SPEED OF SILK MOTHS (BOMBYXMORI L)

In order to find out the action and reason of the oviposition speed promoted by long time copulation, we have made this experiment several times. The result was: the longer and the later was the copulation, the faster was the oviposition speed. In fact, the appearance of promoting the oviposition speed by extending and delaying the time of copulation resulted in delaying the separating time. Thus the number of eggs laid became centralized in a unit time, the oviposition speed was obviously faster. The reason of increasing the oviposition speed is that the later we separated the couple, the riper were the eggs in the moth bodies (internal cause), and the nearer to the dusk the moths laid eggs (external cause).
