Octopamine drives honeybee thermogenesis
In times of environmental change species have two options to survive: they either relocate to a new habitat or they adapt to the altered environment. Adaptation requires physiological plasticity and provides a selection benefit.

Opposing Actions of Octopamine and Tyramine on Honeybee Vision
The biogenic amines octopamine and tyramine are important neurotransmitters in insects and other protostomes. They play a pivotal role in the sensory responses, learning and memory and social organisation of honeybees.

Regulation of Drosophila oviduct muscle contractility by octopamine [PDF]
Summary: Octopamine is essential for egg-laying in Drosophila melanogaster, but the neuronal pathways and receptors by which it regulates visceral muscles in the reproductive tract are not known.

Octopamine in Male Aggression of Drosophila [PDF]
In mammals and humans, noradrenaline is a key modulator of aggression. Octopamine, a closely related biogenic amine, has been proposed to have a similar function in arthropods. However, the effect of octopamine on aggressive behavior is little understood.An automated video analysis of aggression in male Drosophila has been developed, rendering ...

Coumarin‐Based Octopamine Phototriggers and their Effects on an Insect Octopamine Receptor
AbstractWe have developed and characterized efficient caged compounds of the neurotransmitter octopamine. For derivatization, we introduced [6‐bromo‐8‐(diethylaminomethyl)‐7‐hydroxycoumarin‐4‐yl]methoxycarbonyl (DBHCMOC) and {6‐bromo‐7‐hydroxy‐8‐[(piperazin‐1‐yl)methyl]coumarin‐4‐yl}methoxycarbonyl (PBHCMOC) moieties as novel photo‐removable protecting

High-throughput single-fly LC-MS/MS for quantitative profiling of biogenic amines in Drosophila. [PDF]
We present an LC-MS/MS method that enables reproducible, quantitative detection of multiple biogenic amines-including octopamine, dopamine, serotonin, and their precursors-from single Drosophila individuals.

Octopamine modulates insect mating and Oviposition
The neuro-mechanisms that regulate insect reproduction are not fully understood. Biogenic amines, including octopamine, are neuromodulators that have been shown to modulate insect reproduction in various ways, e.g., promote or inhibit insect mating or oviposition.

Octopamine modulates the innate immune response in Drosophila melanogaster [PDF]
BackgroundOctopamine, the functional equivalent of noradrenaline in invertebrates, is a key neuromodulator that also influences immune functions. However, the receptor‑specific roles of octopamine in regulating innate immunity in Drosophila melanogaster ...

Octopamine signaling from clock neurons plays dual roles in Drosophila long-term memory. [PDF]
Circadian clock genes are best known for regulating circadian rhythms, but they also play crucial roles in memory processes. This suggests that memory is modulated by neural networks containing clock neurons, although the underlying mechanisms remain ...

The GABAA receptor RDL modulates the auditory sensitivity of malaria mosquitoes [PDF]
Summary: Malaria mosquitoes acoustically detect mating partners through their flight tones in noisy swarms. Here, we study the auditory role of GABA, one of the main efferent signaling molecules in the mosquito ear, and its interactions with octopamine ...
