SIF_amidein the brain of the sphinx moth,Manduca sexta

Acta Biologica Hungarica, 2012
SIFamides form a group of highly conserved neuropeptides in insects, crustaceans, and chelicerates. Beyond their biochemical commonalities, the neuroanatomical distribution of SIFamide in the insect nervous system also shows a remarkable degree of conservation.

Acetylcholinesterase activity in antennal receptor neurons of the sphinx moth Manduca sexta

Cell and Tissue Research, 1990
We have used a cytochemical technique to investigate the distribution of acetylcholinesterase (AChE) activity in the antenna of the sphinx moth Manduca sexta. High levels of echothiophate-insensitive (presumably intracellular) AChE activity were found in six different types of antennal receptors localized in specific regions of the three antennal ...

Anatomy of antenno-cerebral pathways in the brain of the sphinx moth Manduca sexta

Cell and Tissue Research, 1988
In the moth Manduca sexta, the number and morphology of neuronal connections between the antennal lobes and the protocerebrum were examined. Cobalt injections revealed eight morphological types of neurons with somata adjacent to the AL neuropil that project in the inner, middle, and outer antenno-cerebral tracts to the proto-cerebrum.

Olfactory activation patterns in the antennal lobe of the sphinx moth, Manduca sexta

Journal of Comparative Physiology A, 2003
The sphinx moth Manduca sexta is a well-studied insect with regard to central olfactory functions. Until now, the innervation patterns of olfactory receptor neurons into the array of olfactory glomeruli in the antennal lobe have, however, been unclear. Using optical imaging to visualize calcium dynamics within the antennal lobe we demonstrate specific ...

Visual Control of Compensatory Head Movements in the Sphinx Moth

1990
Insects, like vertebrates and crustaceans, try to stabilize their retinal image by eye movements when the animal or the environment is moving (WEHNER 1981). Because their eyes are integrated in the exoskeleton this task requires the activity of neck muscles turning the head.

Time and Energy Costs of Copulation for the Sphinx Moth, Manduca sexta

Physiological Zoology, 1996
In some insects copulation may represent a significant fraction of reproductive effort, yet its energetics are unexamined. The hawkmoth Manduca sexta, recognized for its endothermy and high metabolic scope (> 100), was largely quiescent during copulation, which averaged about 3 h (n = 31).

Pheromone-evoked potentials and oscillations in the antennal lobes of the sphinx moth Manduca sexta

Journal of Comparative Physiology A: Sensory, Neural, and Behavioral Physiology, 1998
Using intra- and extracellular recording methods, we studied the activity of pheromone-responsive projection neurons in the antennal lobe of the moth Manduca sexta. Intracellularly recorded responses of neurons to antennal stimulation with the pheromone blend characteristically included both inhibitory and excitatory stages of various strengths.

Neuromodulation by 5-Hydroxytryptamine in the Antennal Lobe of the Sphinx Moth Manduca Sexta

Journal of Experimental Biology, 1995
ABSTRACT 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 ...

Pheromone-Modulated Flight Behavior of the Sphinx Moth, Manduca sexta

1994
A complex pattern of zigzagging flight coupled with optomotor anemotaxis brings male moths up a plume of sexual pheromones to locate a female for mating. This behavior has attracted a great deal of interest because of its importance in the life cycle of many species of Lepidoptera, some of them of considerable economic importance as agricultural pests.

Anatomical identification of glomeruli in the antennal lobes of the male sphinx moth Manduca sexta

Cell & Tissue Research, 1992
Computer-assisted neuroanatomical methods have been used to demonstrate unique identities of the glomeruli of the antennal lobes (ALs) in males of the sphinx moth Manduca sexta. The glomerular neuropil consists of the male-specific macroglomerular complex, which comprises two closely apposed bulky subunits, and 64 +/- 1 "ordinary" glomeruli arrayed in ...
