Insights into the Antennal Characteristics and Olfactory Strategy of the Endangered Rhino Stomach Bot Fly Gyrostigma rhinocerontis (Diptera: Oestridae)

Insects, 2022
Gyrostigma rhinocerontis (Diptera: Oestridae) is a rare obligate intestinal parasite of both white and black rhinoceroses, which can induce severe myiasis, cause secondary infection, and lead to enormous economic and scientific loss.

She Doesn't Whisper: Female‐Prominent Stridulation Shaped by Morphology in a Buthid Scorpion and Insights on Its Function

Ethology, EarlyView.
Sexual dimorphism and stress‐induced stridulatory responses in Jaguajir rochae (Borelli, 1910). Females exhibited greater absolute pectinal size and higher sound pressure levels, whereas males showed higher pectinal allometric ratios relative to body size, lower sound frequencies, and shorter delta times.

Characterisation of Bombyx mori odorant-binding proteins reveals that a general odorant-binding protein discriminates between sex pheromone components [PDF]

, 2009
In many insect species, odorant-binding proteins (OBPs) are thought to be responsible for the transport of pheromones and other semiochemicals across the sensillum lymph to the olfactory receptors (ORs) within the antennal sensilla.

Sensing the underground--ultrastructure and function of sensory organs in root-feeding Melolontha melolontha (Coleoptera: Scarabaeinae) larvae. [PDF]

PLoS ONE, 2012
INTRODUCTION: Below ground orientation in insects relies mainly on olfaction and taste. The economic impact of plant root feeding scarab beetle larvae gave rise to numerous phylogenetic and ecological studies. Detailed knowledge of the sensory capacities

Fine Structure and Olfactory Reception of the Labial Palps of Spodoptera frugiperda

Frontiers in Physiology, 2021
The olfactory system of insects is essential in many crucial behaviors, such as host seeking, mate recognition, and locating oviposition sites. Lepidopteran moths possess two main olfactory organs, including antennae and labial palps.

Distinctive gene expression in the reduced first thoracic legs of a nymphalid butterfly

Insect Molecular Biology, EarlyView.
Transcriptome analysis reveals that the small non‐walking front legs of a butterfly have distinct gene expression to the four walking legs. Reduced front legs express a gene with putative mechanosensory roles, a blue‐sensitive opsin and two homeobox genes.

Olfaction in the Spruce Bark Beetle, Ips typographus [PDF]

, 2011
The bark beetle Ips typographus regularly kills spruce trees in the Palearctic. Spruces are colonized by means of attraction to an aggregation pheromone. Attraction is modulated by anti-attractive volatiles (NHV) from non-host plants.

Scanning electron microscopic study of antennal of the female Bee louse fly Braula coeca Nitzsch (Diptera: Braulidae)

مجلة المختار للعلوم, 2014
The antenna of the female bee louse Braula coeca consists of a scape, a pedicel and a Funicle (enlarged basal flagella subsegment). The scape is not visible and does not carry any type of sensilla.

Comparative morphology and plant volatile responses of antennal sensilla in Cinara cedri (Hemiptera: Lachninae), Eriosoma lanigerum (Hemiptera: Eriosomatinae), and Therioaphis trifolii (Hemiptera: Calaphidinae)

Frontiers in Cellular Neuroscience, 2023
Olfaction is important for mediating aphid behaviors and is involved in host location and mating. Antennal primary rhinaria play a key role in the chemoreception of aphids.

Transcriptional responses of Aedes aegypti chemosensory tissues in response to volatile DEET and citronella oil

Insect Molecular Biology, EarlyView.
Aedes aegypti females were significantly repelled by both volatile DEET and citronella oil in comparison to control (ethanol‐exposed) mosquitoes. Global gene expression changes were largest in the mosquito mouthparts, with notable downregulation of the three subunits comprising the mosquito CO2 receptor (Gr1, 2 and 3).
