Bombykal, a Sex Pheromone of the Sphinx Moth Manduca sexta
The first sex pheromone of a Sphinx moth has been isolated from Manduca sexta (Lepidoptera: Sphingidae) with the aid of an electroantennogram assay. It is attractive to males in a field test where its activity might be augmented by a second component in female extracts. Chemical tests and chromatographic properties identify the pheromone as a C16-aldehyde with a pair of conjugated double bonds....
متن کاملNeuromodulation by 5-hydroxytryptamine in the antennal lobe of the sphinx moth Manduca sexta.
Using intracellular recording techniques, we have begun to examine the effects of 5-hydroxytryptamine (5-HT) on antennal-lobe (AL) neurones in the brain of the adult moth Manduca sexta. 5-HT modulated the responses of local interneurones and projection neurones, which were recognized on the basis of well-established electrophysiological criteria, to primary synaptic input elicited by electrical...
متن کاملSexually dimorphic and isomorphic glomeruli in the antennal lobes of the sphinx moth Manduca sexta.
Antennal lobes of adult male and female Manduca sexta were compared in order to investigate the nature and extent of sexual dimorphism of the primary olfactory center of this lepidopteran species. Complete identification of the glomeruli led to the conclusion that all female glomeruli have homologous male counterparts. Thus, there is no sex-specific glomerulus present in one sex and absent in t...
متن کاملCopper/zinc superoxide dismutase-like immunoreactivity in the metamorphosing brain of the sphinx moth Manduca sexta.
Cu/Zn superoxide dismutase (SOD) is part of the defense mechanism that protects cells from being damaged by reactive oxygen species. During metamorphosis of the nervous system, neurons undergo various fates, which are all coupled to high metabolic activities, such as proliferation, differentiation, pathfinding, and synaptogenesis. We describe the pattern of SOD immunoreactivity of identified ne...
متن کاملAn olfactory-specific glutathione-S-transferase in the sphinx moth Manduca sexta.
Insect antennae have a primary function of detecting odors including sex pheromones and plant volatiles. The assumption that genes uniquely expressed in these antennae have an olfactory role has led to the identification of several genes that are integral components of odorant transduction. In the present study, differential display polymerase chain reaction (ddPCR) was used to isolate 25 anten...
