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

    Författare :Sophie Kromann; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : 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. LÄS MER

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

    Författare :Ahmed Saveer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : 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. LÄS MER

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

    Författare :Ali Zakir; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : 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. LÄS MER

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

    Författare :Axel Rösvik; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : 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. LÄS MER

  7. 5. Olfactory mechanisms of host selection in phytophagous insects : behavior, neuron, and receptor

    Författare :Muhammad Binyameen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The most challenging tasks for phytophagous insects are the location and selection of mates, food sources, and oviposition sites, all crucial for survival and reproduction. To perform these tasks insects rely largely on their sense of smell (olfaction). LÄS MER
