Volatile Cues Influence Host-Choice in Arthropod Pests [PDF]

open access: yesAnimals, 2020
Many arthropod pests of humans and other animals select their preferred hosts by recognising volatile odour compounds contained in the hosts’ ‘volatilome’.

Mapping Antennal Sensilla of Boxelder Bugs (Boisea trivittata) as the First Step in Understanding Overwintering Aggregation Behavior [PDF]

open access: yesInsects
Understanding the overwintering behavior of boxelder bugs (Boisea trivittata) is critical for preventing initial aggregation and secondary movement inside structures.

Aquilaria sinensis: An Upstart Resource for Cucurbitacin Production Offers Insights into the Origin of Plant Bitter (Bi) Gene Clusters [PDF]

open access: yesPlants
Cucurbitacins, oxygenated tetracyclic triterpenoids that are found mainly in the Cucurbitaceae family, play essential roles as defensive compounds, serving as allomones against herbivores and pathogens and as signals for insect–parasite recognition ...

Behavioral responses to odors from other species: introducing a complementary model of allelochemics involving vertebrates [PDF]

open access: yesFrontiers in Neuroscience, 2015
It has long been known that the behavior of an animal can be affected by odors from another species. Such interspecific effects of odorous compounds (allelochemics) are usually characterized according to who benefits (emitter, receiver, or both) and the ...

The chemical composition of the secretions, their antibacterial activity, and the pygidial gland morphology of selected European Carabini ground beetles (Coleoptera: Carabidae)

open access: yesFrontiers in Ecology and Evolution, 2023
The pygidial glands of carabids produce strong-smelling vapours. In this study, we examined the chemical composition of the gland secretions and the structure of the glands in five species of Carabini ground beetles (one species from the subtribe ...

Effects of aromatic compounds on movement activity of Pyrrhocoris apterus in the conditions of a laboratory experiment

open access: yesRegulatory Mechanisms in Biosystems, 2022
In the conditions of an urban environment, insects, including Pyrrhocoris apterus (Linnaeus, 1758) (Hemiptera, Pyrrhocoridae), are subject to dozens of volatiles: solvents, food flavorings, cosmetic products.

When Cockroaches Replace Ants in Trophobiosis: A New Major Life-Trait Pattern of Hemiptera Planthoppers Behaviour Disclosed When Synthesizing Photographic Data

open access: yesDiversity, 2023
The mutualistic interspecific relationships of trophobiosis between trophobiont planthoppers (Hemiptera, Fulgoromorpha) providing food to the host called xenobiont, are reviewed.

Tree resin composition, collection behavior and selective filters shape chemical profiles of tropical bees (Apidae: Meliponini). [PDF]

open access: yesPLoS ONE, 2011
The diversity of species is striking, but can be far exceeded by the chemical diversity of compounds collected, produced or used by them. Here, we relate the specificity of plant-consumer interactions to chemical diversity applying a comparative network ...

Response of chrysopids (Neuroptera) to larval tracks of aphidophagous coccinellids (Coleoptera)

open access: yesEuropean Journal of Entomology, 2001
Choice tests showed that tracks left by coccinellid larvae have generally little effect on oviposition site selection by chrysopid females. Fresh tracks of first instar larvae of the coccinellid species Coccinella septempunctata, Cycloneda limbifer, Leis
