Odour intensity learning in fruit flies.

Animals' behaviour towards odours depends on both odour quality and odour intensity. While neuronal coding of odour quality is fairly well studied, how odour intensity is treated by olfactory systems is less clear. Here we study odour intensity processing at the behavioural level, using the fruit fly Drosophila melanogaster. We trained flies by pairing a MEDIUM intensity of an odour with electr...

A model of visual-olfactory integration for odour localisation in free-flying fruit flies.

Flying fruit flies (Drosophila melanogaster) locate a concealed appetitive odour source most accurately in environments containing vertical visual contrasts. To investigate how visuomotor and olfactory responses may be integrated, we examine the free-flight behaviour of flies in three visual conditions, with and without food odour present. While odour localisation is facilitated by uniformly di...

Learning affects mate choice in female fruit flies

Learning in the context of mate choice can influence sexual selection and speciation. Relatively little work, however, has been conducted on the role of learning in the context of mate choice, and this topic has been mostly ignored in insects even though insects have served as a prime model system in research on sexual selection and incipient speciation. Extending recent work indicating apparen...

Learning to find fruit in Ceratitis capitata flies

Wild Mediterranean fruit fly females, Ceratitis capitata (Wiedemann), from an essentially monophagous population on the island of Hawaii were exposed to natural mock orange (Murraya panieulata) or sweet orange (Citrus sinensis) host fruit hung from branches of potted trees for 3-day periods in field enclosures. Subsequently, when flies were released individually onto potted trees harboring one ...

Experimental evolution of learning ability in fruit flies.

The presence of genetic variation for learning ability in animals opens the way for experiments asking how and under what ecological circumstances improved learning ability should evolve. Here we report experimental evolution of learning ability in Drosophila melanogaster. We exposed experimental populations for 51 generations to conditions that we expected to favor associative learning with re...
