Octopaminergic agonists for the cockroach neuronal octopamine receptor
The compounds 1-(2,6-diethylphenyl)imidazolidine-2-thione and 2-(2,6-diethylphenyl)imidazolidine showed the almost same activity as octopamine in stimulating adenylate cyclase of cockroach thoracic nervous system among 70 octopamine agonists, suggesting that only these compounds are full octopamine agonists and other compounds are partial octopamine agonists. The quantitative structure-activity...
متن کاملOctopaminergic dorsal unpaired median (DUM) neurones innervating the colleterial glands of the female cockroach Periplaneta americana
The musculature of the colleterial glands receives innervation from branch 4B4a of the nerves designated 4B, which arise from the posterior part of the terminal abdominal ganglion in the female cockroach Periplaneta americana (L). Using Methylene Blue staining, the gross anatomy of the colleterial gland innervation has been described. Cobalt backfilling via branch 4B4 of nerve 4B revealed about...
متن کاملOctopamine partially restores walking in hypokinetic cockroaches stung by the parasitoid wasp Ampulex compressa.
When stung by the parasitoid wasp Ampulex compressa, cockroaches Periplaneta americana enter a hypokinetic state that is characterized by little, if any, spontaneous locomotor activity. In the present study we investigate the effect of an octopamine receptor agonist and an antagonist on the locomotor behavior of stung and control cockroaches. We show that in cockroaches stung by a wasp the octo...
متن کاملDeciphering the Function of Octopaminergic Signaling on Wing Polyphenism of the Pea Aphid Acyrthosiphon pisum
Aphids exhibit wing polyphenism (winged or wingless) for adaption to predictable or temporally heterogeneous environmental changes; however, the underlying mechanism is still unclear. This morphological change could be stimulated by high aphid density, which in turn could affect octopaminergic signaling in aphids. Octopamine is a neurotransmitter synthesized in insects that can modify their phy...
متن کاملShort Communication Octopamine in a Neurohaemal Area within the Antennal Heart of the American Cockroach
A great deal of research suggests that octopamine functions as a neuromodulator, neurotransmitter and neurohormone in insects (Orchard, 1982; Evans, 1985; Hoyle, 1985). Especially high concentrations of this biogenic amine have been reported for neurohaemal tissue such as the corpora cardiaea and the neurohaemal organs of the medial nervous system (Evans, 1985). In the presented paper, octopami...
