The role of glandular and non-glandular trichomes in the negative interactions between strawberry cultivars and spider mite

Resistance of New Strawberry Genotypes to the Two-Spotted Spider Mite (Acari: Tetranychidae)

“…About 30 years later, Steinite and Ievinsh (2003) concluded that the susceptibility of strawberry cultivars were not related to the density of total trichomes, but rather to the density of glandular trichomes. In relating trichome densities to two-spotted spider mite behavior, Figueiredo et al (2013) showed that on strawberry varieties with greater densities of glandular trichomes the mite moved less, suggesting that this type of evaluation could allow the determination of resistant strawberry cultivars. Although working with a different host plant (tomato), Maluf et al (2007) also concluded that genotypes with higher densities of glandular trichomes had higher mite-resistance, as suggested by an evaluation of the distance walked by the mite onto the tomato leaf surface.…”

“…Varietal resistance can be evaluated through the evaluation of factors such as mite behavior, level of inflicted plant injury (Petrova, Cudare, Steinite, & Laugale, 2000;Wold & Hutchison, 2003), developmental time, survivorship, fecundity, oviposition rate and life table parameters (Gugole Ottaviano, Sánchez, Roggiero, & Greco, 2013;González-Domínguez et al, 2015). Factors related to resistance to mite pests include morphological characteristics such as tissue thickness and density of trichomes (Handley, Ekbom, & Agren, 2005;Oku, Yano, & Takafuji, 2006;González-Domínguez et al, 2015), as well as the production of defense compounds, which often inhibit mite feeding (Steinite & Ievinsh, 2002;Figueiredo, Resende, Morales, Gonçalves, & Da Silva, 2013). The aim of this study was to compare the resistance of eight strawberry genotypes to the two-spotted spider mite, by assessing injury level, biological parameters and host preference.…”

Leaf‐morphology‐assisted selection for resistance to two‐spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae) in carnations (Dianthus caryophyllus L)

“…In previous studies of the resistance of host plants, including tomato and strawberry, to spider mites, leaf surface structure (e.g. glandular trichomes) functioned as the mechanism of host plant resistance . However, carnations have no structure on the leaf surface (Fig.…”

In situ visualization of spider mite-plant interfaces

“…Non-wettable, crystalline waxy, and glandular hairy plant surfaces are known to prevent the attachment of numerous arthropods (e.g., , 2009Voigt et al, 2007). In particular, glandular plant trichomes have been reported to affect spider mites' performance and host preference, as well as to enhance plant resistance against spider mites (Nihoul, 1993;Grazzini et al, 1997;Torre Figueiredo et al 2013). On the tomato Lycopersicon hirsutum f. glabratum Humb & Bonpl.…”

“…Pubescent plant species and cultivars have repeatedly been reported to prevent attacks of spider mites and impact their fitness (e.g., Rasmy, 1985;Luczynski, 1988;Nihoul, 1993;Walter, 1996;Grazzini et al, 1997;Fernández-Muñoz et al, 2003;Reddall et al, 2011;Torre Figueiredo et al, 2013). The effect of host plants on spider mites has been previously assumed to cause morphological changes of tarsal bristles on the forelegs (Fritzsche, 1964).…”
