Chemical communication with volatile semiochemicals in Phyllotreta species (Coleoptera, Chrysomelidae): a minireview

open access: yesInternational Journal of Horticultural Science, 2005
Phyllotreta species (Coleoptera, Chrysomelidae, Halticinae) rank among the most important horticultural pests in the Northern Hemisphere. Leaf damage caused by flea beetles upsets the water balance, blocks plant growth and sometimes causes a high level ...

Sexual Selection and Proteinaceous Diversity in the Femoral Gland Secretions of Lacertid Lizards

open access: yesDiversity, 2023
Sexual selection contributes to the diversity of chemical signals in various animal groups. Lizards are good model species to study how sexual selection shapes signal diversity, as they are a chemically oriented taxonomic group with different levels of ...

Development of a compact, IoT-enabled electronic nose for breath analysis [PDF]

open access: yes, 2020
In this paper, we report on an in-house developed electronic nose (E-nose) for use with breath analysis. The unit consists of an array of 10 micro-electro-mechanical systems (MEMS) metal oxide (MOX) gas sensors produced by seven manufacturers.

Chemical communication between synthetic and natural cells: a possible experimental design [PDF]

open access: yes, 2013
The bottom-up construction of synthetic cells is one of the most intriguing and interesting research arenas in synthetic biology. Synthetic cells are built by encapsulating biomolecules inside lipid vesicles (liposomes), allowing the synthesis of one or ...

A Nose for Death: Integrating Trophic and Informational Networks for Conservation and Management

open access: yesFrontiers in Ecology and Evolution, 2016
Non-lethal management of wildlife, both ‘problem wildlife’ and pest species, to protect crops and threatened species is becoming increasingly important as non-human animals and humans come into closer proximity.

The composition of cuticular compounds indicates body parts, sex and age in the model butterfly Bicyclus anynana (Lepidoptera)

open access: yesFrontiers in Ecology and Evolution, 2014
Chemical communication in insects’ sexual interactions is well-known to involve olfaction of volatile compounds called sex pheromones. In theory, sexual chemical communication may also involve chemicals with low or no volatility exchanged during ...

Comparative Antennal Morphometry and Sensilla Organization in the Reproductive and Non-Reproductive Castes of the Formosan Subterranean Termite

open access: yesInsects, 2021
Antennae are the primary sensory organs in insects, where a variety of sensilla are distributed for the perception of the chemical environment. In eusocial insects, colony function is maintained by a division of labor between reproductive and non ...

Preen gland microbiota covary with major histocompatibility complex genotype in a songbird

open access: yesRoyal Society Open Science, 2021
Pathogen-mediated selection at the major histocompatibility complex (MHC) is thought to promote MHC-based mate choice in vertebrates. Mounting evidence implicates odour in conveying MHC genotype, but the underlying mechanisms remain uncertain.

Queen Recognition Signals in Two Primitively Eusocial Halictid Bees: Evolutionary Conservation and Caste-Specific Perception

open access: yesInsects, 2019
Queen signals are known to regulate reproductive harmony within eusocial colonies by influencing worker behavior and ovarian physiology. However, decades of research have resulted in the identification of just a few queen signals, and studies of their ...
