    Sammanfattning : Sex pheromone communication and related physiological processes are regulated by circadian clock mechanisms in many moth species. This thesis includes studies of circadian rhythms in sexually relevant behaviours and communication in the Egyptian cotton leafworm Spodoptera littoralis, the turnip moth Agrotis segetum, the Indian meal moth Plodia interpunctella and the Mediterranean flour moth Ephestia kuehniella.

    Sammanfattning : Fire is widely recognised for its major impact on boreal forest ecosystems. The altereddisturbance regime due to effective fire suppression and extensive forestry may be a majorthreat to biodiversity.If logging preceded burning, the pyrophilous (Gr. fire-loving) beetle Sericoda quadripunctata failed to reproduce.
