Functional olfactory sensory neurons housed in olfactory sensilla on the ovipositor of the hawkmoth Manduca sexta. [PDF]

Frontiers in Ecology and Evolution, 2016
Olfactory systems evolved to detect and identify volatile chemical cues, in many cases across great distances. However, the precision of copulatory and oviposition behaviors suggest that they may be guided by olfactory cues detected by sensory systems ...

Porous or non-porous? The challenge of studying unusual placoid sensilla of Megaphragma wasps (Hymenoptera, Trichogrammatidae) with electron microscopy [PDF]

Journal of Hymenoptera Research, 2021
Extreme miniaturization implies a high degree of optimization, rendering the retention of non-functional organs almost impossible. Two unique non-porous placoid sensilla on the antennae of females of Megaphragma were described in the literature.

Anatomical Investigation Reveals a Second Olfactory System in Locusts. [PDF]

J Comp Neurol
We traced chemosensory pathways from locust palps through the central nervous system. Olfactory input from basiconic sensilla targets the glomerular lobe and accessory calyx, whereas gustatory input is restricted to gnathal circuits. Thus, the palp and antennal olfactory pathways form parallel but separate systems.

Morphological and Ultrastructural Characterization of Antennal Sensilla and the Detection of Floral Scent Volatiles in Eupeodes corollae (Diptera: Syrphidae)

Frontiers in Neuroanatomy, 2021
The olfactory sensing system of the syrphid fly Eupeodes corollae is essential in pollination and prey localization, but little is known about the ultrastructural organization of their olfactory organs.

Scanning Electron Microscopic Analysis of Antennal Sensilla and Tissue-Expression Profiles of Chemosensory Protein Genes in Ophraella communa (Coleoptera: Chrysomelidae)

Insects, 2022
Ophraella communa is an efficient biocontrol agent used against the invasive weed Ambrosia artemisiifolia. It is an herbivorous insect that feeds on specific plants; the olfactory functions of this insects plays an important role in their search for host

Behavioural manipulation of the cabbage stem flea beetle (Psylliodes chrysocephala L): Prospects for push-pull strategies in oilseed rape. [PDF]

Pest Manag Sci
Behavioural manipulation of Psylliodes chrysocephala provides promising opportunities for sustainable pest management in oilseed rape systems. This review synthesises evidence on glucosinolates and their volatile isothiocyanate derivatives as phagostimulants and attractants, alongside the repellent or antifeedant effects of non‐host plants, plant ...

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.

Find My Way to You: A Comparative Study of Antennal Sensilla and Olfactory Genes in Slug Moth With Different Diet Ranges (Lepidoptera: Limacodidae)

Frontiers in Ecology and Evolution, 2022
Insects and plants that provide them with foods have coexisted for several hundred million years, which leads to various defense approaches and insect-feeding strategies.

On the Larval Sensory Organs and Central Nervous System of the Zoea 1 of the Asian Shore Crab Hemigrapsus sanguineus (Decapoda, Brachyura). [PDF]

J Comp Neurol
We provide a description of the morphology of selected sensory organs and of the central nervous system in the Zoea 1 of the Asian shore crab Hemigrapsus sanguineus using multiple neuroanatomical methods. Our data reveal well‐developed visual and olfactory organs and complex primary sensory neuropils related to processing this input.

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.
