Functional Analysis of Two Odorant-Binding Proteins, MaltOBP9 and MaltOBP10, in Monochamus alternatus Hope

open access: yesFrontiers in Physiology, 2020
Odorant-binding proteins (OBPs) are important for the perception of chemical signals by insects. Effective pest management strategies can be developed by understanding the host location mechanism and the physiological functions of OBPs in olfactory ...

Olfactory sensilla and olfactory genes in the parasitoid wasp Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) [PDF]

open access: yes, 2021
Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) is a tiny natural egg parasitoid of several agricultural pest insects, which has been widely used in the biological control for Plutella xylostella, Helicoverpa armigera, Spodoptera frugiperda

Sensilla-Specific Expression of Odorant Receptors in the Desert Locust Schistocerca gregaria

open access: yesFrontiers in Physiology, 2019
The desert locust Schistocerca gregaria recognizes multiple chemical cues, which are received by olfactory sensory neurons housed in morphologically identifiable sensilla.

The specific expression patterns of sensory neuron membrane proteins are retained throughout the development of the desert locust Schistocerca gregaria

open access: yesCurrent Research in Insect Science, 2023
The desert locust Schistocerca gregaria detects odorants through olfactory sensory neurons (OSNs) that are surrounded by non-neuronal support cells (SCs).

A carboxylesterase, Esterase-6, modulates sensory physiological and behavioural response dynamics to pheromone in Drosophila [PDF]

open access: yes, 2012
Background: Insects respond to the spatial and temporal dynamics of a pheromone plume, which implies not only a strong response to"odor on", but also to"odor off". This requires mechanisms geared toward a fast signal termination.

Extracellular Transduction Events Under Pulsed Stimulation in Moth Olfactory Sensilla [PDF]

open access: yesChemical Senses, 2003
In natural conditions, pheromones released continuously by female moths are broken in discontinuous clumps and filaments. These discontinuities are perceived by flying male moths as periodic variations in the concentration of the stimulus, which have been shown to be essential for location of females. We study analytically and numerically the evolution

EFFECT OF GAMMA RADIATION ON MORPHOLOGY OF SENSORY STRUCTURES FOR THE ANTENNAE OF Trogoderma granarium (Everts.) ADULTS [PDF]

open access: yesJournal of Plant Protection and Pathology, 2002
External morphology of antennal sensilla of both sexes of irradiated and non- irradiated Trogoderma granarium were studied with scanning electron microscopy. The number and distribution of antennal sensilla were also determined. Five types of sensilla

OSCILLATIONS OF THE TRANSEPITHELIAL POTENTIAL OF MOTH OLFACTORY SENSILLA ARE INFLUENCED BY OCTOPAMINE AND SEROTONIN [PDF]

open access: yesJournal of Experimental Biology, 2001
SUMMARYThe biogenic amine octopamine is known to enhance the sensitivity of male moths to their species-specific pheromones in flight-tunnel experiments. This sensitization of pheromone-guided upwind flight is at least partly due to octopamine-dependent increases in the peak nerve impulse frequency of the pheromone response of olfactory receptor ...

Central projections of olfactory receptor neurons from single antennal and palpal sensilla in mosquitoes [PDF]

open access: yes, 2003
In insects, olfactory receptor neurons (ORNs) are located in cuticular sensilla, that are present on the antennae and on the maxillary palps. Their axons project into spherical neuropil, the glomeruli, which are characteristic structures in the primary ...

Oscillatory Sequences of Firing in the Locust Olfactory System: Mechanisms and Functional Significance [PDF]

open access: yes, 1999
What neural codes does the brain use to represent and process sensory information? Stimulus-evoked oscillatory synchronization of neuronal activity has been observed in many systems, yet the possible functions of such rhythmic synchronization in neural ...
