Fine Structure of Antennal Sensilla of Paysandisia archon and Electrophysiological Responses to Volatile Compounds Associated with Host Palms. [PDF]

PLoS ONE, 2015
Paysandisia archon (Lepidoptera: Castniidae) is a serious pest of palm trees. A comprehensive knowledge of the insect olfactory system is essential for the development of efficient semiochemical-based control methods.

Identification and analysis of odorant receptors expressed in the two main olfactory organs, antennae and palps, of Schistocerca americana

Scientific Reports, 2022
Locusts depend upon their sense of smell and provide useful models for understanding olfaction. Extending this understanding requires knowledge of the molecular and structural organization of the olfactory system.

Secondary Rhinaria Contribute to Major Sexual Dimorphism of Antennae in the Aphid Semiaphis heraclei (Takahashi)

Insects, 2023
Sexual generation is an important generation in the life cycle of host-alternating aphids, and its population size determines the intensity of the peak in the next spring.

An RNA-seq screen of the Drosophila antenna identifies a transporter necessary for ammonia detection. [PDF]

PLoS Genetics, 2014
Many insect vectors of disease detect their hosts through olfactory cues, and thus it is of great interest to understand better how odors are encoded.

The Sensilla-Specific Expression and Subcellular Localization of SNMP1 and SNMP2 Reveal Novel Insights into Their Roles in the Antenna of the Desert Locust Schistocerca gregaria

Insects, 2022
Insect olfactory sensilla house olfactory sensory neurons (OSNs) and supports cells (SCs). The olfactory sensory processes require, besides the odorant receptors (ORs), insect-specific members of the CD36 family, named sensory neuron membrane proteins ...

Sensory memory for odors is encoded in spontaneous correlated activity between olfactory glomeruli [PDF]

, 2006
Sensory memory is a short-lived persistence of a sensory stimulus in the nervous system, such as iconic memory in the visual system. However, little is known about the mechanisms underlying olfactory sensory memory.

Antennal sensory structures of Phenacoccus solenopsis (Hemiptera: Pseudococcidae)

Frontiers in Zoology, 2022
Background The cotton mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) is one of the most devastating sap-sucking pests of cultivated plants. The success of P.

Odorant Responses and Courtship Behaviors Influenced by at4 Neurons in Drosophila. [PDF]

PLoS ONE, 2016
In insects, pheromones function as triggers to elicit complex behavior programs, such as courtship and mating behavior. In most species, the neurons tuned to pheromones are localized in a specific subset of olfactory sensilla located on the antenna ...

Ir76b is a Co-receptor for Amine Responses in Drosophila Olfactory Neurons

Frontiers in Cellular Neuroscience, 2021
Two large families of olfactory receptors, the Odorant Receptors (ORs) and Ionotropic Receptors (IRs), mediate responses to most odors in the insect olfactory system. Individual odorant binding “tuning” OrX receptors are expressed by olfactory neurons in

Recent Insights into Insect Olfactory Receptors and Odorant-Binding Proteins

Insects, 2022
Human and insect olfaction share many general features, but insects differ from mammalian systems in important ways. Mammalian olfactory neurons share the same overlying fluid layer in the nose, and neuronal tuning entirely depends upon receptor ...
