“…Szyndler et al . [15] previously showed that the hooked trichomes in kidney bean ( Phaseolus vulgaris ) physically entrap and impale bedbugs ( Cimex lectularius ), thereby preventing them from moving on the leaf surface. We also observed physical damage to caterpillars (leakage of hemolymph) in our experiments, mainly caused by the sharp spikes of stellate trichomes.…”

Leaf trichomes play well-established roles in defense against insect herbivores, both as a physical barrier that impedes herbivore movement and by mediating chemical defenses. However, little work has examined how different trichome types influence herbivory by herbivores at different stages of development. We examined whether caterpillar instar and trichome type (glandular or non-glandular) affected the ability of the specialist herbivore caterpillar Manduca sexta to initiate feeding on 11 Solanaceous species exhibiting variation in the density and type of leaf trichomes. Our results suggest that non-glandular trichomes are far more effective than glandular trichomes in deterring the initiation of feeding by first- and second-instar caterpillars. Meanwhile, neither glandular nor non-glandular trichomes significantly affected the ability of third-instar caterpillars to commence feeding. These findings suggest that while non-glandular trichomes deter feeding initiation by early instar caterpillars, the contribution of both trichomes on later instars may depend on effects after feeding initiation.

“…The capture mechanism involved the physical impaling of bed bug feet (tarsi) by hooked trichomes, in a distinct way from the Velcro-like mechanism of non-piercing entanglement. Using bean leaves as templates, and plant cell wallslike polymers, Szyndler et al (2013) microfabricated surfaces indistinguishable in geometry from the real leaves, including the trichomes. Despite snagging the bed bugs temporarily they did not hamper their locomotion as effectively as natural bean leaves.…”

“…Based on popular knowledge that strewn kidney beans (Phaseolus vulgaris) leaf were used for trapping bed bugs, Szyndler et al (2013) identified the structural features involved in the mechanical capture by these leaves, in order to design biomimetic surfaces for bed bug ⁄ ä (Figueiredo and Pais 1992), (h and n).

Taking the best out of plants, namely from medicinal and aromatic plants (MAP), involves understanding their structural and chemical features, in connection with their biological roles, and, no less important, realizing the principles behind their use by plants. Plants are exquisitely sensitive to biotic and abiotic environmental changes. Nevertheless, plants are unique in their renewal capacity, since they can produce meristems during their life time, and in showing developmental plasticity, i.e., the ability to change its development in response to diverse factors. This means that a plant can very often survive, despite having been partially eaten, and/or that a single plant genotype can be expressed under different phenotypes, and the one(s) expressed will depend on local environmental stimuli. From man point of view this may have importance, as these different phenotypes can be associated to different chemotypes, which may have a tremendous implication on the biological activity of plant man-valued products and on their commercial value. Some of the structural and chemical traits involved in plant-abiotic and plant-biotic defence, and in attraction interactions, with some examples on how man uses some of these traits and mechanisms to his benefit, are here revised. Apoplastic barriers, glandular or non-glandular structures, mimicry, plant, or plant parts, movements, abiotic environmental relationships, interaction with pathogens and phytophagous and attraction of pollinators and seed dispersers, are discussed. In each case, plants use both constitutive, as well as inducible traits. Nevertheless, it is noteworthy that constitutive traits are not always constant. Indeed, constitutive structural and chemical features can be permanent or transient, depending on the plant developmental stage. Despite all available traits, plants are endowed with self-defence mechanisms against their own toxins. The awareness of plant structural and chemical adaptative features purposes can complement the knowledge derived from evolutionary studies, and provide us the know-how to project and develop plants with improved traits, or procedures based on their modus operandi and/or better plant (nano-)products.
