A novel strain sensor based on the campaniform sensillum of insects [PDF]

open access: yesPhilosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2002
The functional design of the campaniform sensillum was modelled as a hole in a plate using two- and three-dimensional finite-element modelling. Different shapes of opening in a fibrous composite plate amplify differently the global strains imposed on the plate, and different configurations of reinforcement also have an effect.

Ultra-Morphology and Mechanical Function of the Trichoideum Sensillum in Nabis rugosus (Linnaeus, 1758) (Insecta: Heteroptera: Cimicomorpha)

open access: yesInsects, 2022
The present study aims to investigate the morphological features of the antennal sensilla by using SEM and TEM. The construction of a 3D model of trichoideum sensillum using Amira software is presented in this paper.

Microstructural Adaptation for Prey Manipulation in the Millipede Assassin Bugs (Hemiptera: Reduviidae: Ectrichodiinae)

open access: yesBiology, 2023
Species in Ectrichodiinae are known for their prey specialization on millipedes. However, knowledge of the morphological adaptations to this unique feeding habit was limited.

Ultrastructure of Antennal Sensilla in Adults of Dioryctria rubella Hampson (Lepidoptera: Pyralidae)

open access: yesInsects, 2021
Antennal sensilla play an essential role in insect life because they receive environmental cues. Dioryctria rubella is an important pine pest in China, but information on the morphology and distribution of its sensilla is limited.

Single-Sensillum Taste Recordings in Mosquitoes

open access: yesCold Spring Harbor Protocols, 2023
In insects, gustatory neurons sense chemicals upon contact and directly inform many behaviors critical for survival and reproduction, including biting, feeding, mating, and egg laying. However, the taste sensory system is underexplored in many anthropophilic disease vectors such as mosquitoes, which acquire and transmit human pathogens during blood ...

A moth odorant receptor highly expressed in the ovipositor is involved in detecting host-plant volatiles

open access: yeseLife, 2020
Antennae are often considered to be the nostrils of insects. Here, we sequenced the transcriptome of the pheromone gland-ovipositor complex of Helicoverpa assulta and discovered that an odorant receptor (OR) gene, HassOR31, had much higher expression in ...

Unique Fine Morphology of Mouthparts in Haematoloecha nigrorufa (Stål) (Hemiptera: Reduviidae) Adapted to Millipede Feeding

open access: yesInsects, 2020
Millipede assassin bugs are a diverse group of specialized millipede predators. However, the feeding behavior of Ectrichodiinae remains poorly known, especially how the mouthpart structures relate to various functions in feeding.

Insects Can Count: Sensory Basis of Host Discrimination in Parasitoid Wasps Revealed. [PDF]

open access: yesPLoS ONE, 2015
The solitary parasitoid Leptopilina heterotoma is one of the best studied organisms concerning the ecology, behaviour and physiology of host discrimination. Behavioural evidence shows that L.

How Does the Intricate Mouthpart Apparatus Coordinate for Feeding in the Hemimetabolous Insect Pest Erthesina fullo?

open access: yesInsects, 2020
The yellow marmorated stink bug, Erthesina fullo (Thunberg, 1783), is a major pest of certain tree fruits in Northeast Asia. To better understand the feeding mechanism of E.

Ultrastructural studies on the antennal sensilla of Pteromalus puparum L. (Hymenoptera: Pteromalidae)

open access: yes浙江大学学报. 农业与生命科学版, 2000
Antennal surface structure of Pteromalus puparum L. was observed by scanning electron microscope. Seven types of sensilla, namely, thick-walled chemoreceptor, thin-walled chemoreceptor, plate organ, short-curved tactile hair, sharp-tipped tactile hair ...
