Both serotonin (5-HT) and neuropeptide Y have been shown to affect a variety of mammalian behaviors, including aggression. Here we show in Drosophila melanogaster that both 5-HT and neuropeptide F, the invertebrate homolog of neuropeptide Y, modulate aggression. We show that drug-induced increases of 5-HT in the fly brain increase aggression. Elevating 5-HT genetically in the serotonergic circuits recapitulates these pharmacological effects, whereas genetic silencing of these circuits makes the… 
Sex differences in aggression: Differential roles of 5-HT2, neuropeptide F and tachykinin
TLDR
A more nuanced role for 5-HT in modulating aggression in invertebrates is demonstrated, revealing an important interactive role with neuropeptides that is more reminiscent of vertebrates.
Modulatory Action by the Serotonergic System: Behavior and Neurophysiology in Drosophila melanogaster
TLDR
The results demonstrate that disruption of components within the 5-HT system significantly impairs locomotion and feeding behaviors in larvae and that fluoxetine can significantly decrease the sensory-motor activity.
Targeted Manipulation of Serotonergic Neurotransmission Affects the Escalation of Aggression in Adult Male Drosophila melanogaster
TLDR
Evidence is collected demonstrating a direct role for 5HT in the escalation of aggression in Drosophila by separately manipulating 5HT- and DA- neuron systems.
A neuropeptide regulates fighting behavior in Drosophila melanogaster
TLDR
It is found that the neuropeptide Drosulfakinin (Dsk) modulates aggression in Drosophila melanogaster and this work suggests a conserved neuromodulatory system for the modulation of aggressive behavior.
A Single Pair of Serotonergic Neurons Counteracts Serotonergic Inhibition of Ethanol Attraction in Drosophila
TLDR
The results reveal that compensation can occur on the circuit level and that serotonin has a bidirectional function in modulating the innate attraction to ethanol and delineate a basic principle for how random behavior is switched into targeted approach behavior.
Serotonin in Animal Cognition and Behavior
TLDR
The roles of 5-HT, illustrated in both invertebrates and vertebrates, show that it is more able to potentiate or mitigate the neuronal responses necessary for the fine-tuning of most behaviors, rather than to trigger or halt a specific behavior.

TLDR
The results suggest that NPY acting through Y1 receptors regulates the 5-HT system, thereby coordinately linking physiological survival mechanisms such as food intake with enabling territorial aggressive behavior.
Drosophila neuropeptide F and its receptor, NPFR1, define a signaling pathway that acutely modulates alcohol sensitivity.
TLDR
A Drosophila signaling system, comprising neurons expressing neuropeptide F and its receptor, NPFR1, that acutely mediates sensitivity to ethanol sedation is identified, providing the molecular and neural basis for the strikingly similar alcohol-responsive behaviors between flies and mammals.
Sex- and clock-controlled expression of the neuropeptide F gene in Drosophila
TLDR
It is proposed that NPF also plays a role in clock-controlled sexual dimorphism in adult Drosophila, and is under dual regulation by circadian and sex-determining factors.

TLDR
This paper concentrates on the involvement of protein elements in the brain neurotransmitter serotonin (5-HT) system in the genetic control of aggressive behavior and provides converging lines of evidence that brain 5-HT contributes to a critical mechanism underlying genetically defined individual differences in aggressiveness.
Neuropeptide y: role in emotion and alcohol dependence.
TLDR
The recent developments elucidating the role of NPY in emotion and alcohol dependence are reviewed and the potential of the NPY system as a novel therapeutic strategy in the treatment of anxiety, depression and alcohol-related disorders is examined.
Drosophila as a new model organism for the neurobiology of aggression?
TLDR
Drosophila, with its advanced set of molecular tools and its behavioural richness, has the potential to develop into a new model organism for the study of the neurobiology of aggression.

Regulation of aversion to noxious food by Drosophila neuropeptide Y– and insulin-like systems
TLDR
The results suggest that the coordinated activities of the conserved NPY- and insulin-like receptor signaling systems are essential for the dynamic regulation of noxious food intake according to the animal's energy state.
