Profiling the Nematicidal Activity of Linear and Cyclic Compounds on the Pinewood Nematode
The pinewood nematode (PWN), <i>Bursaphelenchus xylophilus</i>, has become one of the most damaging pests to forest health in Asia and Europe. In the screening for sustainable biopesticides, research has focused on highly active secondary metabolites. In the present work, 25 linear and c...

| description | The pinewood nematode (PWN), <i>Bursaphelenchus xylophilus</i>, has become one of the most damaging pests to forest health in Asia and Europe. In the screening for sustainable biopesticides, research has focused on highly active secondary metabolites. In the present work, 25 linear and cyclic pure compounds, commonly found in essential oils (EOs) and extracts, were preliminarily tested in direct contact bioassays against the PWN to understand how distinct chemical structures can be related to a stronger nematicidal activity. Their activity appeared to be strongly related to specific functional groups, isomerism, or the length of the linear carbon chain. Uncovering the variation in the structure–activity relationships of anti-PWN compounds contributes to the identification of the nematicidal mechanisms of action as a basis for improving sustainable pest management in forest ecosystems. |
