当转移到连续光照下时，求偶行为变得不活泼和不规则，而产生的性信息素量却等于或高于14L∶10D光周期下所产生的性信息素量。

This result indicates that both events have a circadian periodicity . When moths were shifted to continuous light at day 2 , calling became inactive and irregular , whereas pheromone titres were equal or higher than those of moths under 14L ∶ 10D .
