Beeinflussen verschiedene Volatilenmuster die Wirtspflanzenwahl unterirdisch lebender Insekten? [PDF]

open access: yes, 2008
Cockchafers of the genus Melolontha (Coleoptera: Scarabaeidae) can be severe pests in forestry, agriculture and horticulture. Gradation of the two most important species, the forest cockchafer M. hippocastani FABR.

A natural barrier: tick‐repellent potential of a spruce‐derived volatile blend against Hyalomma excavatum and Ixodes ricinus

open access: yesPest Management Science, Volume 82, Issue 2, Page 1481-1491, February 2026.
Both active and passive questing ticks, Hyalomma excavatum and Ixodes ricinus, were assessed for behavioural responses to two novel plant‐derived repellent volatile organic compound blends. Both tick species were repelled by the products, and both novo blends were significantly more repellent than currently available commercial products.

Multiple signalling increases both prey response and diversity in a carnivorous pitcher plant

open access: yesFunctional Ecology, Volume 40, Issue 2, Page 451-462, February 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Organisms across the tree of life use multiple signals such as colour, movement sound, and many types of chemical signals to convey seemingly the same information. These signals are potentially costly, yet the repeated evolution of multiple signalling across systems ...

From beginning to end: the synecology of tree‐killing bark beetles, fungi, and trees

open access: yesBiological Reviews, Volume 101, Issue 1, Page 314-335, February 2026.
ABSTRACT Over a century of research has revealed an amazing complexity of behaviours and physiological adaptations that allow tiny bark beetles to overcome large trees, sometimes resulting in outbreaks that kill millions of trees. Turning a tree into a home and successfully raising offspring involves constant interactions among the beetles, the tree ...

Synthesis of chiral 2-methyl-5,6,7,8-tetrahydroquinolines from naturally occurring monoterpenes [PDF]

open access: yes, 2004
The synthesis is reported of chiral substituted 2-methylpyridines, in which the pyridine rings are annulated at the 5,6-positions to the chiral frameworks originating from (-)-β-pinene, (-)-isopinocampheol and (+)-camphor.

Active chitosan coating to inhibit decay and maintain mango postharvest quality

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 2, Page 1394-1406, 30 January 2026.
Abstract BACKGROUND Microbial decay limits the storage, quality and trade of mangoes (Mangifera indica). We developed an active chitosan coating containing zinc oxide nanoparticles (ZnO‐NPs) and Eucalyptus radiata essential oil (EEO) to inhibit decay and preserve postharvest quality of mango. Chitosan (cationic) can disrupt microbial membranes; ZnO‐NPs

The effects of alpha‐pinene against paracetamol‐induced liver damage in male rats

open access: yesPhysiological Reports
This study aims to evaluate the hepatoprotective effect of alpha‐pinene against N‐acetyl‐p‐aminophenol, paracetamol, (APA)‐induced liver damage in rats. Thirty Wistar rats were divided into five groups (n = 6): Group 1: Normal (control). Group 2: APA 640

Synthesis of terpinyl acetate from α-pinene catalyzed by α-hydroxycarboxylic acid-boric acid composite catalyst.

open access: yesPLoS ONE
To enhance the yield of the one-step synthesis of terpinyl acetate from α-pinene and acetic acid, this study evaluated α-hydroxycarboxylic acid (HCA)-boric acid composite catalysts based on orthogonal experimental design.
