The macroglomerular complex of the antennal lobe in the tobacco budworm moth Heliothis virescens : specified subdivision in four compartments according to information about biologically significant…
Abstract The functional organisation of the male specific macroglomerular complex in Heliothis virescens has been studied by tip recordings of sensilla trichodea type 1 combined with cobalt-lysine… Expand

Digital atlases of the antennal lobe in two species of tobacco budworm moths, the oriental Helicoverpa assulta (male) and the American Heliothis virescens (male and female)
The antennal lobe of the moth brain is the primary olfactory center processing information about pheromones and plant odors. We present here a digital atlas of the glomerular antennal lobe structures… Expand

Projections of male‐specific receptor neurons in the antennal lobe of the oriental tobacco budworm moth, Helicoverpa assulta: A unique glomerular organization among related species
The macroglomerular complex in the primary olfactory center of male moths receives information from numerous pheromone‐detecting receptor neurons housed in specific sensilla located on the antennae.… Expand

γ-Aminobutyric acid immunostaining in the antennal lobe of the moth Heliothis virescens and its colocalization with neuropeptides
The antennal lobe is the primary processing center for olfactory information in insects. To understand further the neural circuitry of this brain area, we have investigated the distribution of… Expand

Consistent organization of glomeruli in the antennal lobes of related species of heliothine moths
The glomeruli of the antennal lobes in insects reflect the organization of the olfactory system, which is important for species‐specific behaviors in response to insect‐ and plant‐produced odorants.… Expand

The significance of major pheromone components and interspecific signals as expressed by receptor neurons in the oriental tobacco budworm moth, Helicoverpa assulta
Receptor neuron specificities for intra- and interspecific chemical signals were determined in males of Helicoverpa assulta, by testing single neurons for twelve heliothine produced compounds and two… Expand

Characterization of three pheromone-binding proteins (PBPs) of Helicoverpa armigera (Hübner) and their binding properties.
Three pheromone-binding proteins of Helicoverpa armigera were cloned and expressed in Escherichia coli. In order to characterize their physiological properties, ligand-binding experiments were… Expand

Processing of Pheromone Information in Related Species of Heliothine Moths
In heliothine moths, the male-specific olfactory system is activated by a few odor molecules, each of which is associated with an easily identifiable glomerulus in the primary olfactory center of the… Expand

Antennal-lobe tracts in the noctuid moth, Heliothis virescens: new anatomical findings
As in other insects, three main tracts in the moth brain form parallel connections between the antennal lobe and the protocerebrum. These tracts, which consist of the antennal-lobe projection-neuron… Expand

Distribution of neuropeptides in the primary olfactory center of the heliothine moth Heliothis virescens
Neuropeptides are a diverse widespread class of signaling substances in the nervous system. As a basis for the analysis of peptidergic neurotransmission in the insect olfactory system, we have… Expand
