  2. 1. Modulation of olfactory information in the antennal lobe of Spodoptera littoralis

    Author : Sophie Kromann; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In order to respond appropriately to external stimuli, e.g. odours in the environment,insects have to evaluate these stimuli in a context of relevance and need. These decisions are, in turn, based on internal physiological status, such as mating status. READ MORE

  4. 2. Recognition and modulation of olfactory signals in the noctuid moth spodoptera littoralis

    Author : Ahmed Saveer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Food, mates and host plants are essential resources for plant-feeding insects. Optimal resource localization that fulfils the physiological need and reproductive goals of an insect is of utmost importance. READ MORE

  5. 3. Influence of herbivore-induced changes in host plants on reproductive behaviours in Spodoptera littoralis : herbivore-plant interactions

    Author : Ali Zakir; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Insect herbivores orient towards host plants using sensory cues and olfaction plays a major role, especially in nocturnal herbivores, during selection of host plants suitable for feeding, mating and oviposition. Plants defend themselves from herbivore feeding by producing volatiles as well as non-volatiles chemical compounds. READ MORE

  6. 4. Finding the right one : Host-plant choice and its transgenerational influence on behaviour and life-history traits in Spodoptera littoralis

    Author : Axel Rösvik; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Herbivorous insects have an intricate relationship with their host plants, which they use as food, oviposition substrate, as well as a rendezvous site for mating. For generalist herbivorous insects that have a wide host range, finding a suitable host plant in a complex environment is of great importance for their offspring’s development and survival.

  7. 5. Social and environmental olfactory signals mediate insect behavioral ecology and evolution

    Author : Felipe Borrero; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Odors are essential in mediating insect reproductive behavior. Environmental odors help insects locate suitable feeding or egg-laying sites and avoid suboptimal hosts or dangerous habitats. Sex pheromones, on the other hand, are responsible for mate finding and elicit courtship and mating. READ MORE
