Odour cues are crucial for adult female and male parasitoids throughout their life span. The attraction of parasitoids to the odours of plants, hosts, food sources, conspecifics and competitors have been studied using various methods and tools, mostly in different types of olfactometers and wind tunnels. For this thesis we developed a novel olfactometer for highthrough-put bio-assays. In chapter...

Feeding on carbohydrate food sources is critical for survival and reproductive success of adult parasitoids. This means that females of many parasitoids will have to periodically interrupt host foraging to find food. If host and food are located in different patches, food searching can be time and energy consuming. This is especially true for most agricultural monocultures were nectar is...
