Nature’s Sticky Trap: Wild Tomato Trichome Rupture by a Thrips Nymph 🍅🪰


Published on: 10 June 2025


Witness the real-world application of a plant's "chemical landmine" defense. This color video captures a thrips nymph (Frankliniella occidentalis) navigating a section of wild tomato stem (Solanum habrochaites), where it inadvertently triggers the rupture of a Type VI glandular trichome.


In this interaction, the insect’s leg applies mechanical stress to the trichome’s glandular head, causing a sudden brittle fracture at the intermediate cell junction. This ultra-fast event—occurring in less than a millisecond—instantly releases a reservoir of stored secondary metabolites. The video highlights how the released fluid wets the insect's body, transforming from a liquid droplet into sticky, adhesive filaments that can immobilize the pest.
