Octopamine causes a dose-dependent increase in juvenile hormone release from corpora allata. Maximum increase is obtained with concentrations of 10−6 M in nurse and foraging bees by 45.3 or 32.3%, respectively. Octopamine-like immunoreactivity occurs in about 45 somata of the median neurosecretory cells in the pars intercerebralis of the bee brain. They project via immunopositive nervus corporis cardiaci I into the corpora cardiaca, where interspersed varicose structures and 8–10 cell bodies in the ventral part of this gland are stained. A network of immunoreactive fine varicose nerve fibres surrounds each gland cell of the corpora allata. Immunoreactivity in these neuronal structures is detectable if bees were starved over night, a condition in which corpora allata elicit the highest juvenile hormone production ever observed in bees. Both, the stimulatory effect of octopamine and the presence of immunoreactive nerve fibers in the corpora allata, strongly indicate a physiological role of this biogenic amine in the regulation of juvenile hormone biosynthesis in adult honey bees.</dcterms:abstract> <dc:creator>Kreißl, Sabine</dc:creator> <dc:rights>deposit-license</dc:rights> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103605204-4002607-1"/> <dc:creator>Kaatz, Hannes</dc:creator> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-10-13T11:39:28Z</dc:date> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/16324"/> <dc:contributor>Kaatz, Hannes</dc:contributor> <dc:language>eng</dc:language> <dc:contributor>Eichmüller, Stefan</dc:contributor> <dcterms:issued>1994</dcterms:issued> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-10-13T11:39:28Z</dcterms:available> <dc:contributor>Kreißl, Sabine</dc:contributor> <dcterms:bibliographicCitation>First publ. in: Journal of Insect Physiology ; 40 (1994), 10. - pp. 865-872</dcterms:bibliographicCitation> <dc:creator>Eichmüller, Stefan</dc:creator> </rdf:Description> </rdf:RDF>
