Trace amines are endogenous compounds classically regarded as comprising β-
phenylethyalmine, p-tyramine, tryptamine, p-octopamine, and some of their metabolites …

▪ Abstract Octopamine (OA) and tyramine (TA) are the invertebrate counterparts of the
vertebrate adrenergic transmitters. They are decarboxylation products of the amino acid …

The catecholamines play a major role in the regulation of behavior. Here we investigate, in
the fly Drosophila melanogaster, the role of dopamine and octopamine (the presumed …

In insects, olfaction plays a crucial role in many behavioral contexts, such as locating food,
sexual partners, and oviposition sites. To successfully perform such behaviors, insects must …

Many complex factors have been linked to the recent marked increase in honey bee colony
failure, including pests and pathogens, agrochemicals, and nutritional stressors. It remains …

Octopamine biosynthesis requires tyrosine decarboxylase to convert tyrosine into tyramine
and tyramine β-hydroxylase to convert tyramine into octopamine. We identified and …

Honeybees exhibit two patterns of organization of work. In the spring and summer, division
of labor is used to maximize growth rate and resource accumulation, while during the winter …

There is increasing worldwide concern about the impacts of pesticide residues on honey
bees and bee colony survival, but how sublethal effects of pesticides on bees might cause …

This review will focus on the relationships between sensory responses of bees and
behavior. Sensory responsiveness constrains individual foraging plasticity and skews …

Sleep is a fundamental process, but its regulation and function are still not well understood.
The Drosophila model for sleep provides a powerful system to address the genetic and …
