[Calling and mating behaviors of adult Orthaga achatina (Lepidoptera: Pyralidae)].
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.
