Ultrastructural Morphology and Descriptive Analysis of Cuticular Sensilla in Adult Tomicus pilifer (Coleoptera: Curculionidae)

Insects
Tomicus pilifer is a major pest that threatens Pinus koraiensis forests in the northeast region of China. In this study, we employed scanning electron microscopy (SEM) to observe the sensilla on the antennae, mouthparts, and legs of both male and female ...

Effects of essential amino acids on phagostimulation and reproduction in adults of the Mediterranean fruit fly Efectos de amino ácidos esenciales en la fago‐estimulación y reproducción en adultos de la mosca de las frutas del Mediterráneo

Physiological Entomology, EarlyView.
The phagostimulation and reproductive effects of individual essential amino acids, without other nutrient except fructose, were investigated. Methionine, Arginine and Leucine display significantly higher phagostimulation strength than fructose. Arginine and Methionine showed a significant improvement in reproductive activity compared to other tested ...

Olfactory responses and sensilla morphology of the blackcurrant leaf midge Dasineura tetensi [PDF]

Entomologia Experimentalis et Applicata, 1999
AbstractOlfactory responses of Dasineura tetensi (Rubs) (Diptera; Cecidomyiidae) to leaf volatiles of blackcurrant (Ribes nigrum) were tested in a 4‐way olfactometer. Newly emerged virgin females showed no response to the leaf volatiles emitted from a blackcurrant shoot.

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

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.

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

Insect Molecular Biology, Volume 35, Issue 5, Page 504-516, October 2026.
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.

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.

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.

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

Insect Molecular Biology, Volume 35, Issue 5, Page 526-540, October 2026.
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).
