    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 : The impact of olfactory and auditory cues on the mating behaviour in two species of moths, Agrotis segetum (Noctuidae) and Plodia interpunctella (Pyralidae), was investigated to evaluate their potential use in integrated pest management. The flight behaviour of male A. LÄS MER

  5. 4. Chemical communication in leaf mining moths of the genus phyllonorycter

    Författare :Raimondas Mozuraitis; KTH; []
    Nyckelord :;

    Sammanfattning : Laboratory studies of pheromone release behaviour haverevealed that virgin females of all of the nine species of thegenus Phyllonorycter investigated demonstrated the samepheromone release posture. Their calling activity wasregistered at the beginning of the photophase. This is anunusual time for calling in moths. LÄS MER

    Sammanfattning : The perpose of this study is to clarify how the visitation of the sick could be carried out in Swedish medieval and Reformation traditions. It aims to answer questions concerning the rituals, what their theological and pious meaning was and how medieval liturgy and custom could survive, change or be abolished in the Reformation tradition.
