A global-wide search for sexual dimorphism of glomeruli in the antennal lobe of female and male Helicoverpa armigera
Zhao, Xin-Cheng; Ma, Bai-Wei; Berg, Bente Gunnveig; Xie, Gui-Ying; Tang, Qing-Bo; Guo, Xian-Ru (Journal article; Peer reviewed, 2016)By using immunostaining and three-dimensional reconstruction, the anatomical organization of the antennal lobe glomeruli of the female cotton bollworm Helicoverpa armigera was investigated. Eighty-one glomeruli were ... -
Brain Organization of Apolygus lucorum: A Hemipteran Species With Prominent Antennal Lobes
Xie, Gui-Ying; Ma, Bai-Wei; Liu, Xiao-Lan; Chang, Ya-Jun; Chen, Wen-Bo; Li, Guo-Ping; Feng, Hong-Qiang; Zhang, Yong-Jun; Berg, Bente Gunnveig; Zhao, Xin-Cheng (Journal article; Peer reviewed, 2019)The anatomical organization of distinct regions in the insect brain often reflects their functions. 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 ... -
Distribution of tachykinin-related peptides in the brain of the tobacco budworm Heliothis virescens
Zhao, Xin-Cheng; Xie, Gui-Ying; Berg, Bente Gunnveig; Schachtner, Joachim; Homberg, Uwe (Journal article; Peer reviewed, 2017)Invertebrate tachykinin-related peptides (TKRPs) comprise a group of signaling molecules having sequence similarities to mammalian tachykinins. A growing body of evidence has demonstrated the presence of TKRPs in the central ... -
Functional map of the macroglomerular complex of male Helicoverpa armigera
Liu, Xiaolan; Chu, Xi; Sun, Long-Long; Wang, Ya-Nan; Xie, Gui-Ying; Chen, Wen-Bo; Liu, Yang; Berg, Bente Gunnveig; An, Shi-Heng; Wang, Gui-Rong; Yin, Xin-Ming; Zhao, Xin-Cheng (Peer reviewed; Journal article, 2022)The mechanism of sex pheromone reception in the male cotton bollworm Helicoverpa armigera has been extensively studied because it has become an important model system for understanding insect olfaction. However, the pathways ... -
Glomerular identification in the antennal lobe of the male moth Helicoverpa armigera
Zhao, Xin-Cheng; Chen, Qiu-Yan; Guo, Pei; Xie, Gui-Ying; Tang, Qing-Bo; Guo, Xian-Ru; Berg, Bente Gunnveig (Journal article; Peer reviewed, 2016)This study investigates anatomical organization of the antennal lobe (AL) glomeruli of the male cotton bollworm Helicoverpa armigera by synaptic antibody staining combined with three-dimensional reconstruction. To identify ... -
Processing of pheromone information in related species of Heliothine moths
Berg, Bente Gunnveig; Zhao, Xin-Cheng; Wang, Guirong (Journal article; Peer reviewed, 2014)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 brain. This arrangement ... -
Representation of pheromones, interspecific signals, and plant odors in higher olfactory centers; mapping physiologically identified antennal-lobe projection neurons in the male heliothine moth
Zhao, Xin-Cheng; Kvello, Pål; Løfaldli, Bjarte Bye; Lillevoll, Siri Corneliussen; Mustaparta, Hanna; Berg, Bente Gunnveig (Journal article; Peer reviewed, 2014)The arrangement of anatomically separated systems for information about general and pheromone odorants is well documented at the initial levels of the olfactory pathway both in vertebrates and insects. In the primary ... -
Revisiting the Labial Pit Organ Pathway in the Noctuid Moth, Helicoverpa armigera
KC, Pramod; Chu, Xi; Kvello, Pål; Zhao, Xin-Cheng; Wang, Gui-Rong; Berg, Bente Gunnveig (Peer reviewed; Journal article, 2020)Lepidopteran species detect CO2 via a specialized organ located on the peripheral segment of the labial palps, the labial palp pit organ (LPO). Based on tracing of LPO sensory neurons targeting one distinct antennal-lobe ...
