Olfactory Strategies in the Defensive Behaviour of Insects
Most animals must defend themselves in order to survive. Defensive behaviour includes detecting predators or intruders, avoiding them by staying low-key or escaping or deterring them away by means of aggressive behaviour, i.e., attacking them.

From Cohesion to Norms: How Animal Groups Come, Stay, and Function Together
The present review underscores two salient points: In the context of evolutionary transitions to pair‐ and group living, it is imperative to acknowledge the distinction between selective forces that act during the origin of these social systems and those that act during their subsequent maintenance.

Fire Ant Venom Alkaloids: Possible Control Measure for Soilborne and Foliar Plant Pathogens
The purpose of this study was to evaluate fire ant venom alkaloids and an alarm pheromone analog against several plant pathogens, including Botrytis cinerea, Fusarium oxysporum, Phytophthora nicotianae, P.

Ecology and evolution of pyrazines in insects
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Social communication activates the circadian gene Tctimeless in Tribolium castaneum
Chemical communication via pheromones is an integral component in insect behavior, particularly for mate searching and reproduction. Aggregation pheromones, that attract conspecifics of both sexes, are particularly common and have been identified for ...

Balancing risk and opportunity: Nasute termite responses to predator and competitor chemical cues
Nasutitermes corniger discriminates between heterospecific chemical cues during foraging, showing non‐random resource selection based on predator and competitor information. Predator chemical cues consistently reduce food resource selection, indicating avoidance driven by perceived predation risk rather than direct encounters.

Abstract Specimens of an unknown Ipini were trapped during 2023–2024 exotic forest pest surveys in County Clare, Ireland. This non‐native species was provisionally identified as Pseudips mexicanus (Hopkins, 1906) with morphological identification keys. However, damaged specimens could not be confidently identified to the species level.

ABSTRACT Understanding the chemical and behavioural ecology of the Neotropical brown stink bug, Euschistus heros (Hemiptera: Pentatomidae), is essential for developing effective integrated pest management (IPM) strategies in South American soybean production. This study investigated the courtship behaviour and diel periodicity of sex pheromone emission.

Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits
Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.

ABSTRACT Male sticklebacks (Gasterosteidae) produce an adhesive protein called “spiggin” in the tubular epithelial cells of their kidneys, which they use to attach plants or plant debris together and build nesting sites. Spiggin is a glycoprotein excreted in urine.
