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

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

3. Social and environmental olfactory signals mediate insect behavioral ecology and evolution
Abstract : Odors are essential in mediating insect reproductive behavior. Environmental odors help insects locate suitable feeding or egg-laying sites and avoid suboptimal hosts or dangerous habitats. Sex pheromones, on the other hand, are responsible for mate finding and elicit courtship and mating. READ MORE

4. Circadian Rhythms in Moth Sex Pheromone Communication
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.

5. Recognition and modulation of olfactory signals in the noctuid moth spodoptera littoralis
Abstract : 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. READ MORE
