Comparative Neuroanatomy of Hydrothermal Vent Shrimps: Ecological Differentiation Among Four Alvinocaridid Species. [PDF]

J Comp Neurol
Hydrothermal vent shrimps share a conserved brain architecture with enlarged mushroom bodies and terminal medullae, shaped by similar environmental pressures. Despite this similarity, some anatomical features near the brain vary between species, suggesting that some ecological factors, such as microhabitat and trophic strategies, also influence nervous

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

Chemical 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]

Journal 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]

Journal 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 ...

Integrating vision, audition and olfaction traits: a roadmap for contrasting sensory ecologies of birds and rodents

Oikos, EarlyView.
Sensory ecology seeks to understand how organisms detect and use information from their environment, yet comparative analyses across multiple sensory modalities remain rare. Here, we present a roadmap for contrasting the sensory ecologies of birds and rodents using surrogate morphological and acoustic traits associated with vision, audition, and ...

Re-Classification of Drosophila melanogaster Trichoid and Intermediate Sensilla Using Fluorescence-Guided Single Sensillum Recording.

PLoS ONE, 2015
Drosophila olfactory receptor neurons are found within specialized sensory hairs on antenna and maxillary palps. The linking of odorant-induced responses to olfactory neuron activities is often accomplished via Single Sensillum Recordings (SSR), in which

Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Evolution of coeloconic sensilla in the peripheral olfactory system of Drosophila mojavensis

Journal of Insect Physiology, 2018
Populations inhabiting habitats with different environmental conditions, such as climate, resource availability, predation, competition, can undergo selection for traits that are adaptive in one habitat and not the other, leading to divergence between populations.

Morphology and Distribution of Antennal Sensilla in Three Species of Thripidae (Thysanoptera) Infesting Alfalfa Medicago sativa

Insects, 2021
Thrips are important pests to alfalfa Medicago sativa. Similar as many other plant-feeding insects, thrips rely on the antennae to receive chemical signals in the environment to locate their hosts.

Ozone‐driven degradation of sex pheromone in Plutella xylostella: Implications for reproductive communication and mating success

Insect Science, EarlyView.
In this study, we examined whether realistic ozone concentrations can interfere with sexual communication in the insect pest Plutella xylostella, the diamondback moth. Ozone exposure caused a degradation of pheromone components, leading to significant changes in blend composition and component ratios.
