在（27 ± 1）℃、（60 ± 10）% RH、14 L：10 D光周期条件下，对圆额蛾成虫的求偶和交配行为进行了实验研究。女性O。achatina在暗相开始时才发出叫声，在暗相开始后的第5小时叫声百分率急剧上升，在暗相开始后的第6 ~ 7小时达到高峰。不同蛾龄的成虫的鸣叫率不同，以2- 3d龄最高（> 70%）。交配行为可分为两个连续的时期，求偶期和交配期。雌、雄O.无翅期出现在暗期的第5 ~ 9小时，高峰出现在进入暗期的第6 ~ 7小时，与雌蛾求偶行为的高峰期相一致。雌性一生只交配一次。给药1组雌性：与处理1雌：1雄相比，处理2雄的交配率显著提高，但交配持续时间显著缩短。
A laboratory study was made on the calling and mating behaviors of adult Orthaga achatina at (27 +/- 1) degrees C, (60 +/- 10)% RH, and 14 L: 10 D photoperiod. The female O. achatina did not call until the start of scotophase, with the calling percentage increased sharply at the 5th hour and reached the peak at the 6th-7th hour of scotophase. The calling percentage varied with moth age, being the highest (> 70%) at the age of 2-3 d. The mating behavior could be divided into two successive periods, i.e., calling period and mating period. The mating between female and male O. achatina occurred during the 5th-9th hour of scotophase, with the peak at the 6th-7th hour into scotophase, which was in accordance with the peak time of female calling behavior. Females mated only one time during their whole life. Treatment 1 female : 2 male showed a significantly higher mating percentage, but a significantly shorter mating duration time, compared with treatment 1 female : 1 male.
