🪲 SPECIAL ISSUE REVIEW 🪲

Non-host resistance is the most common, durable, and efficient outcome of plant defences against biotic stresses. This review highlights its role in plant–insect interactions- Pinheiro et al. 📝

#PlantScience 🧪
Fig 3. Conceptual representation of pre- and post-herbivory resistance in plants. Plant non-host resistance to herbivorous insects can be understood as a two-stage phenomenon comprising pre- and post-herbivory resistance. In pre-herbivory resistance, the plant employs visual and olfactory signals to halt insects from making physical contact with a potential host. This includes the emission of repellent volatiles, the display of warning pigments on plant organs (aposematic colours), and modification of leaf shape and size. Additionally, certain plant traits promote association with insect natural enemies (tritrophic interaction). In post-herbivory resistance, the plants utilize mechanosensory or gustatory traits to hinder the ability of insect larvae to traverse, injure, and digest the plant material. This includes the production of surface waxes, glandular and non-glandular trichomes, proteins that counteract the function of insect digestive proteins, and toxic metabolites.

I wrote (ranted) on experimental design as I was frustrated as an editor at how little guidance students were getting. I underestimated the interest in the issue: it has been downloaded 10,000+ times! Clearly it’s something we need to be talking about more. onlinelibrary.wiley.com/doi/full/10....
Principles of experimental design for ecology and evolution
Here I argue that we do not discuss experimental design, often until it is too late. This editorial seeks to begin a conversation about how and where to replicate appropriately.
