摘要: The bamboo shoot borer, Apamea apameoides (Lepidoptera: Noctuidae) is an important pest damaging bamboo shoots in south China. To understand the courtship and mating behaviors of A. apameoides adults is critical for the identification and application of its sex pheromone. The sex ratio, lifespan and courtship and mating behaviors of A. apameoides adults were studied in the laboratory. The results indicated that the ratio of female to male was 1:0.76. The lifespan of the virgin female and unmated male was shortened after copulation. The courtship and mating behaviors of A. apameoides occurred only in the scotophase, and moth age had a significant effect on the courtship and mating behaviors. The females began courting in the first scotophase after adult emergence, and the peak of courtship occurred during the second scotophase. The mean onset time of courtship advanced significantly with the increased moth age. Mating of A. apameoides adults initiated during the first scotophase, and the peak of mating was observed during the third scotophase. The mean onset time of mating advanced with the increase of moth age, and the time of copulation peak had no significant difference among different moth ages.
