TL;DR: The chemical composition of essential oil of leaves of Piper aduncum L., growing wild in a fragment of the Atlantic Rainforest biome in northeastern Brazil, was determined through gas chromatography-mass spectrometry and the repellent activity was attributed to the components (E)-nerolidol, α-humulene and β-caryophyllene, whereas toxicity by fumigation and contact was attributed.

TL;DR: The role of terpenoids in the acaricidal property of E. langsdorffii essential oils was also discussed in this paper, where a comparative study to assess fumigant and residual contact toxicities of the oils was conducted, showing that the residual contact effect of the fruit oil (LC50 = 12.25 µL mL-1) was just 6.7 times smaller than that of eugenol.

TL;DR: Fumigant and residual effects of Lippia oil were more selective than eugenol with regard to a natural enemy of T. urticae, Neoseiulus californicus.

TL;DR: The results suggest that the repellent activity of these oils in association with its toxicity could be a great advantage for the integrated management of T. urticae.

TL;DR: The results demonstrated that the essential oils of M. indica can destroy L. amazonensis and inhibit tumor cell growth and contribute to the knowledge of the Brazilian biodiversity as a source of potential therapeutic agents.
