  2. 1. Studies in pest control for cultural property

    Author : Thomas Strang; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; Pest control; cultural property collections; insect; mould; environment; integrated pest management; IPM; thermal control; pest risk to museum collections;

    Abstract : This thesis considers discrete problems of protecting cultural property from pests and examines some of the solutions. Recent decades have seen a large change in how fumigants and pesticides are used in collections of cultural property. READ MORE

  4. 2. 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

  5. 3. Semiochemical-mediated attraction and oviposition in pyralid moths

    Author : Christian Olsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ekologi; Lepidoptera; behaviour; pest control; Ecology; learning; olfaction;

    Abstract : Moths use chemical signals emanating from food to find sites for oviposition and subsequent larval feeding. By identifying these odours, novel approaches to pest management can be developed, such as monitoring of females in pest populations. READ MORE

  6. 4. On the Regulation of Ornithine Decarboxylase

    Author : Eva Lövkvist Wallström; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysiologi; Physiology; Crithidia fasciculata.; polyamines; Ornithine decarboxylase; translational control; osmolarity; untranslated region; COS cells; CHO cells; transfection; protein turnover; PEST region;

    Abstract : The polyamines putrescine, spermidine and spermine have been shown to be involved in cell growth and differentiation, and are considered to be crucial components of the living cell. The synthesis of polyamines in the cell is strictly regulated. READ MORE

  7. 5. Pyralid moth reproduction: Communication, Constraints & Control

    Author : Camilla Ryne; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; plant parasitology; Entomology; växtparasitologi; Entomologi; Animal ecology; Djurekologi; Chemistry; Kemi;

    Abstract : Olfactory cues play an important role in the reproduction of three pyralid moths, the Indian meal moth (Plodia interpunctella), the Mediterranean flour moth (Ephestia kuehniella) and the almond moth (E. cautella). Both males and females of P. interpunctella are capable of multiple matings. READ MORE
