TL;DR: A passive sampling technique, the Radiello diffusive sampler, is tested to monitor the cadaveric VOCs released by decomposing pig carcasses in three biotopes (crop field, forest, urban site) and identified 104 chemical compounds exclusively produced by the decompositional process.

TL;DR: The monoterpene R-(+)-limonene did not affect the females’ foraging behavior, whereas (Z)-3-hexenol and EβF increased the time of flight and acceptance of the host plant, suggesting that selection of the oviposition site by predatory hoverflies relies on the perception of a volatile blend composed of prey pheromone and typical plant green leaf volatiles.

TL;DR: This report reports the first isolation of a bacterium from the pea aphid Acyrthosiphon pisum honeydew, Staphylococcus sciuri, which acts as a kairomone enhancing the efficiency of aphid natural enemies and has a key role in tritrophic interactions.

TL;DR: In this article, an analysis of the released molecules from 23 aphid species, mainly collected on their natural host plant from May to July, was performed by gas chromatography-mass spectrometry.

TL;DR: The results support the potential usefulness of (E)-β-farnesene and (−)- β-caryophyllene in push–pull strategies that use H. axyridis as a biological control agent in aphid-infested sites or to control this new urban pest in residential structures.
