4. 2. Pheromone production in the butterfly Pieris napi L

   Author : Rushana Murtazina; Raimondas Mozuraitis; Joop van Loon; KTH; []
   Keywords : Pieris; Lepidoptera; pheromone; aphrodisiaca; antiaphrodisiaca; biosynthesis; flower volatiles; stable isotopes; incorporation; neral; geranial; methyl salicylate; benzyl cyanide; L - phenylalanine;

   Abstract : Aphrodisiac and anti-aphrodisiac pheromone production and composition in the green-veined white butterfly Pieris napi L. were investigated.Aphrodisiac pheromone biosynthesis had different time constraints in butterflies from the diapausing and directly developing generations.

5. 3. Chemical Communication and Mate Choice : Investigations into the Meaning of a Fruit Fly Pheromone

   Author : Björn G. Johansson; Göran Arnqvist; Fredrik Widemo; Anders Berglund; Allen Moore; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Drosophila grimshawi; sexual selection; pheromone; mate choice; lekking; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

   Abstract : Chemical signals are the most widely used form of sexual communication throughout the living world. However, there is in general little knowledge about what these signals actually communicate. The role of chemical signals, i.e. READ MORE

6. 4. Insights into the Evolution of Moth Pheromone Communication: Lessons from the European Corn Borer

   Author : Jean-Marc Lassance; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biosynthetic enzymes; evolution; Ostrinia nubilalis; mate choice; mate finding; olfaction; biosynthesis; speciation; moth; pheromone; olfactory receptors.;

   Abstract : Chemical communication by means of sex pheromones is central to the mating systems of a wide range of organisms. Because reproductive isolation is often based on pheromone differences, understanding how pheromones diverge is necessary for a complete comprehension of the speciation process. READ MORE

7. 5. Circadian Rhythms in Moth Sex Pheromone Communication

   Author : Germund von Wowern; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physiology of invertebrates; växtparasitologi; Entomologi; plant parasitology; Entomology; Ecology; Ekologi; locomotor activity; social synchronisation; PDH; corazonin; PBAN; pheromone response; sex phermone; Lepidoptera; Ryggradslösa djurs fysiologi; calling behaviour; circadian rhythm;

   Abstract : 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.
