Abstract The clock gene period ( per ) is a regulator of circadian rhythms but may also play role in the regulation ultradian rhythms, such as insect courtship. Males parasitoid wasp Nasonia vitripennis court females by performing series head movements (‘head-nods’) and wing vibrations within repeated cycles. pattern cycle duration head-nod number species-specific has genetic basis. In this stu...

Abstract The effects of mating experience on male behavior are mediated by four factors: cost, such as resource depletion, perception opportunities, self-perception attractiveness, and female quality. For example, encountering females might increase expectations prospective while copulation increases attractiveness in males. To determine the relative importance these factors, effect two compone...

Complex courtships have been described for neotropical frogs, but detailed quantifications of calls emitted during this behavior are still rare. Herein, we describe the courtship call Bokermannohyla ibitiguara, a gladiator tree frog from Brazilian Cerrado, as well female courtship, and clutch characteristics. Moreover, statistically compare acoustic parameters advertisement calls. We observed t...

Understanding how neural circuits in the brain respond to external cues resulting in behavioral changes is an important aspect of neuroscience research. A valuable model in this endeavor is the neural circuitry governing courtship behavior in the fruit fly Drosophila melanogaster. New work provides detailed insights into how factors such as sex pheromones direct the intricate courtship behavior...

Male Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) used their aristae to repeatedly tap the female, usually on her aristae, during the second stage of head rocking courtship. The male’s antennae moved in an apparently exploratory manner earlier in head rocking. Reduced rates of copulation followed removal of male and female aristae, supporting the idea that tapping with the aristae is a...

The performance of a task is often assumed to be a prerequisite for the learning of many tasks, including the associative conditioning of courtship in the fruit fly, Drosophila melanogaster. Transgenic flies specifically inhibited for the enzyme protein kinase C dissociate the acquisition of learning and memory from performance of the task. They fail to show immediate suppression of courtship b...
