Anatomical organization of second order neurons in the primary olfactory brain center of the model organism Heliothis virescens
Berg, Aleksander (Master thesis, 2013)Luktesansen er den eldste av sansene. Grunnet dens mindre håndgripelige natur sammenliknet med de andre sansene er den ofte blitt mystifisert. Selv om flere hundre millioner år skiller virveldyr og insekters felles stamfar ... -

In the present study, the brain structure of Apolygus lucorum was examined by using immunolabeling and three-dimensional ... -
Central Projections of Antennal and Labial Palp Sensory Neurons in the Migratory Armyworm Mythimna separata
Ma, Bai-Wei; Zhao, Xin-Cheng; Berg, Bente Gunnveig; Xie, Gui-Ying; Tang, Qing-Bo; Wang, Gui-Rong (Journal article; Peer reviewed, 2017)The oriental armyworm, Mythimna separata (Walker), is a polyphagous, migratory pest relying on olfactory cues to find mates, locate nectar, and guide long-distance flight behavior. In the present study, a combination of ... -
Central Projections of Gustatory Receptor Neurons in the Medial and the Lateral Sensilla Styloconica of Helicoverpa armigera Larvae
Tang, Qing-Bo; Zhan, Huan; Cao, Huan; Berg, Bente Gunnveig; Yan, Feng-Ming; Zhao, Xin-Cheng (Journal article; Peer reviewed, 2014)Food selection behavior of lepidopteran larvae is predominantly governed by the activation of taste neurons present in two sensilla styloconica located on the galea of the maxilla. In this study, we present the ultrastructure ... -
Characterization of functionally different projection neurons in the olfactory pathway of the male moth, Heliothis virescens
Hannaas, Ragnhild (Master thesis, 2014)Most organisms, ranging from mammals to bacteria, are dependent of their sense of smell in order to survive and reproduce. In moths, the detection of odorants is performed by olfactory sensory neurons located on the antenna. ... -
Coincidence of pheromone and plant odor leads to sensory plasticity in the heliothine olfactory system
Ian, Elena; Kirkerud, Nicholas N.; Galizia, C. Giovanni; Berg, Bente Gunnveig (Journal article; Peer reviewed, 2017)Male moths possess a highly specialized olfactory system comprised of two segregated sub-arrangements dedicated to processing information about plant odors and pheromones, respectively. Communication between these two ... -
