Two compounds showed the almost same activity as octopamine in stimulating adenylate cyclase of cockroach thoracic nervous system among 70Octopamine agonists, suggesting that only these compounds are full octopamines agonists and other compounds are partial octopaminergic agonists.

Neurotransmitter-receptors as targets for new insecticides
Using structure-activity relationships, a number of high affinity agonists of this receptor subtype are characterized and a variety of these compounds show a high degree of specificity for insect octopamine receptors versus vertebrate adrenergic receptors.
Octopamine receptor subtypes and their modes of action
- BiologyNeurochemical Research
The current status of this classification is reviewed by examining the pharmacology of responses to octopamine in a range of preparations and it is concluded that the distinction between OCTOPAMINE1 and OCTopAMINE2 receptor types is still valid, but that OCTOPamINE2 receptors exhibit some tissue specific variations.

Comparison of the relative binding affinities of various PIIs for mammalian alpha-adrenergic receptors, as well as the ability of various antagonists to block PII binding, strongly suggested that the active PIIs are affecting a class of octopamine receptors distinct from mammalian alpha 1- or alpha 2-adRenergic receptors.

Octopamine in insects: neurotransmitter, neurohormone, and neuromodulator
It is shown that octopamine can act as a neurotransmitter, a neurohormone, and a neuromodulator within the nervous system of invertebrates and in locusts, an identified octopaminergic neuron innervates the extensor-tibiae muscle of the hind legs.

A hypothesis, termed the Orchestration Hypothesis is presented, which considers how modulator neurons such as locust octopaminergic neurons, might be involved in the generation of specific behaviors.
