Sound production during agonistic behavior of maleDrosophila melanogaster

Sound production during agonistic behavior of male Drosophila melanogaster.

Male Drosophila fruit flies acquire and defend territories in order to attract females for reproduction. Both, male-directed agonistic behavior and female-directed courtship consist of series of recurrent stereotypical components. Various studies demonstrated the importance of species-specific sound patterns generated by wing vibration as being critical for male courtship success. In this study...

The Study of Agonistic Behavior

Agonistic Behavior and Acoustic Communication

Sounds are uttered in agonistic contexts by representatives of 30+ families of fishes but this number mainly reflects the scientific expenditure and less so the actual distribution of soundproducing families. Sounds are emitted in numerous contexts: distressful or disturbancesituations, e.g. being attacked or grabbed by predators, competitive feeding, and competition for space and sometimes mat...

The effect of neurospecific knockdown of candidate genes for locomotor behavior and sound production in Drosophila melanogaster

Molecular mechanisms underlying the functioning of central pattern generators (CPGs) are poorly understood. Investigations using genetic approaches in the model organism Drosophila may help to identify unknown molecular players participating in the formation or control of motor patterns. Here we report Drosophila genes as candidates for involvement in the neural mechanisms responsible for motor...

Effect of olfactory stimulation during suckling on agonistic behavior in weaned pigs

Materials and methods: Six Control group sows and six treatment (Banana) group sows were used, each with 10 piglets. Treatment consisted of daily topical application of isoamyl acetate (banana scent) on the skin of the sows’ mammary glands during the 21 days of suckling. Preference of the piglets for the banana scent was tested with a V-maze at 4 and 21 days of age. After weaning, pigs were reg...
