  1. 1. Disruption of moth mating behaviour by olfactory and auditory cues

    Author : Glenn Svensson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; ultrasound; predation risk; selection; heritability; flight tunnel; harmonic radar; pest control; mating disruption; pheromone communication; Pyralidae; Lepidoptera; Noctuidae; Animal ecology;

    Abstract : 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. READ MORE

  2. 2. Molecular aspects of pheromone evolution in moths

    Author : David Abraham; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ekologi; 28S genephylogenetic reconstruction pheromone types; ND1 genes; PBP; Pheromone-binding protein genes; Drepanidae; Noctuidae; Geometridae; Lepidoptera; Insect; Evolution; Olfaction; Ecology;

    Abstract : Moths rely on the sense of smell (olfaction) as the main sensory input system in search for potential food sources and in selection of suitable females by males. Specific pheromones are fundamental to the reproductive isolation of species and consequently the olfactory system of moths has evolved to a high level of sensitivity and specificity. READ MORE

  3. 3. Odour-mediated nectar foraging in the silver Y moth, Autographa gamma

    Author : Dainius Plepys; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; predation risk; Noctuidae; Lepidoptera; flight tunnel; GC-EAD; single sensillum; sprayer; ultrasound; floral volatiles; attraction; foraging; mate-finding; lilac aldehydes; olfactory receptor neurones; Ecology; Ekologi; Chemistry; Kemi;

    Abstract : It is well established that floral odours play a significant role in the nectar foraging behaviour in Lepidoptera and other insect orders. Floral odour may elicit searching, alighting and feeding behaviours alone or in concert with visual stimuli. READ MORE

  4. 4. Male moth behaviour and perception in pheromone plumes

    Author : Peter Valeur; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; Grapholita molesta; Noctuidae; Lepidoptera; Tortricidae; behaviour; electrophysiology; single cell; flight tunnel; sex pheromone; wind tunnel; radar; flight; pre-exposure; mechanisms of mating disruption; Agrotis segetum; choice test;

    Abstract : Behaviour of male moths and electrophysiological responses of male pheromone-specific olfactory receptor neurones were studied in two model species, the oriental fruit moth Grapholita molesta and the turnip moth Agrotis segetum. The studies were aimed at elucidating the relative importance of different mating disruption mechanisms. READ MORE

  5. 5. Pheromones, genes & transcriptomes. A molecular analysis of moth sex pheromone production

    Author : Maria Strandh; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Female moths emit sex pheromones to lure a mate. In this thesis I examined the transcriptomes of female moth pheromone glands in order to identify genes encoding proteins involved in pheromone production. Two cDNA-libraries were constructed from Agrotis segetum (Noctuidae) pheromone glands and the remaining body tissue, respectively. READ MORE
