Sammanfattning : In a series of studies, carried out in the laboratory and in the field in southern Sweden, I have examined factors influencing the mating behaviour of the turnip moth Agrotis segetum. The reproductive potential of the sexes and the mating behaviour was studied. The reproductive potential of males is greater than that of females. LÄS MER
Sammanfattning : 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.

4. Chemical Communication and Mate Choice : Investigations into the Meaning of a Fruit Fly Pheromone
Sammanfattning : 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. LÄS MER
5. Insights into the Evolution of Moth Pheromone Communication: Lessons from the European Corn Borer
Sammanfattning : 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. LÄS MER
