“…The density of total trichomes had no influence on the results regarding resistance, as demonstrated by the fact that even though the cultivar Camarosa presented a higher concentration of total trichomes, it was more preferred than Camino Real, indicating that a higher density of glandular trichomes confers resistance in the genotype more efficiently. The glandular trichomes and non-glandular trichomes present on strawberry leaflets are promoters of two-spotted spider mite resistance through constitutive mechanisms (Benatto;Penteado;Zawadneak, 2019;Hata et al, 2020). Resistance in strawberry plants is attributed to constitutive and inductive defense mechanisms that protect against pest attack (Kalec et al, 2017).…”

“…In contrast, the plant only expresses induced defense when injury occurs, and this type of resistance directly affect herbivores or natural enemies (Smith;Clement, 2012;Moreira et al, 2018). Trichomes are important constitutive defense mechanisms; there are two types of trichomes described in strawberry plants: glandular and non-glandular trichomes (Benatto;Penteado;Zawadneak, 2019;Hata et al, 2020). The resistance of cultivars to spider mites is related to the density of the glandular trichomes, which store substances hindering the herbivore's walking and feeding (Oliveira et al, 2018;Bac-Molenaar et al, 2019).…”

Strawberry genotypes with resistance to Tetranychus urticae mediated by leaf trichomes

The two-spotted spider mite (Tetranychus urticae) is the main pest encountered in strawberry cultivation in protected environments, causing damage and increasing the cost of production associated with chemical control. Breeding programs are essential for obtaining new cultivars that are more tolerant to two-spotted spider mites. The objective was to evaluate whether the leaf trichomes mediatethe resistance of intraspecific strawberry hybrids to two-spotted spider mites. Preselected hybrids were subjected to infestation by two-spotted spider mites and evaluated via the no-choice assay and the travel test. Resistance was correlated with the density of trichomes, both glandular and non-glandular, present on the surface of the leaflets of strawberry genotypes. The results indicated that there is an influence of hybrids and cultivars on the behavior of the pest, allowing the verification of the existence of resistant genotypes (RVDA#16, RVCS#44 and Camino Real). These treatments resulted in low numbers of eggs deposited and hatched compared with the other treatments and shorter distances traveled by two-spotted spider mites on the surface of leaflets. It was also verified that the glandular trichomes presented a significant negative correlation with the average distance traveled by two-spotted spider mites on the surface of the leaf discs, indicating that these structures alter the behavior of these arthropods. Genotype resistance was associated with the presence of glandular trichomes. In addition to the superiority of the agronomic and postharvest attributes of the preselected hybrids (RVDA#16 and RVCS#44) identified in the previous selection efforts, they proved to be promising materials for achieving resistance to the spider mite, revealing important genotypes for use as cultivars and particularly as parents in breeding programs.

“…Biological control agents can be effective for the management of strawberry pests when used preventatively or on the condition that there is early detection and intervention 18,19 . An exception is found for the specialist strawberry aphid Chaetosiphon fragaefolii , a major strawberry pest worldwide 20,21 . This aphid species causes both direct plant damage and indirect plant damage by transmitting viruses such as mild yellow‐edge virus (SMYEV), strawberry crinkle cytorhabdovirus (SCV), and strawberry mottle virus (SMoV) that reduce plant vigour and negatively impact yield 22 .…”

BACKGROUND: Predatory syrphids are an important functional group due to their potential for providing multiple ecosystem services. Adults feed on nectar and pollen, and can be effective pollinators, while larvae are voracious predators that can reduce aphid pressure. Still, little research has addressed their potential dual function in agroecosystems. In this study, we assessed the potential of two predatory hoverflies, Eupeodes corollae and Sphaerophoria rueppellii, for delivering concurrent pollination and biological control of Chaetospihon fragaefolii in greenhouse strawberries.RESULTS: Both hoverfly species effectively pollinated strawberry flowers of two different varieties ('Elsanta' and 'Sonsation'), resulting in an increase in high-quality marketable fruits, a reduction of fruit deformities, and higher number of seeds per fruit compared to pollinator-excluded fruits. S. ruepellii had a significantly longer flower handling time than E. corollae, which translated to a more efficient pollination expressed as higher seed numbers per fruit after a single flower visit. By contrast, flowers that were open to multiple visits were more effectively pollinated by E. corollae, suggesting that E. corollae is potentially a better cross-pollinator than S. rueppellii. In addition, both hoverfly species suppressed aphid populations in strawberry (var. 'Sonata'), with S. rueppellii and E. corollae reducing aphid populations by 49% and 62%, respectively. CONCLUSION: Predatory syrphids can concurrently contribute to pollination and biological control in strawberry in a greenhouse setting.

“…Heavily infested plants show symptoms, such as leaf chlorosis, wilting and malformations and may eventually die [2]. Among the harmful sucking pests, the cotton or melon aphid Aphis gossypii (Glover), the strawberry aphid Chaetosiphon fragaefolii (Cockerell) (Hemiptera: Aphididae) and the Western flower thrip Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) are of great interest because in all their developmental stages, they deprive plants of nutrients [2][3][4][5] and at the same time transmit viral diseases [3][4][5][6][7], resulting in significant financial losses in the production of commercially important crop species, such as melons and strawberries.…”

Dual Action of Beauveria bassiana (Hypocreales; Cordycipitaceae) Endophytic Stains as Biocontrol Agents against Sucking Pests and Plant Growth Biostimulants on Melon and Strawberry Field Plants

et al. 2022

Entomopathogenic fungi (EPF) can colonize plant tissues and serve crops not only as biopesticides but also as biostimulants that promote plant growth and trigger defense mechanisms. In this context, field trials were conducted evaluating two commercial strains of the entomopathogen Beauveria bassiana (Hypocreales: Cordycipitaceae), GHA (Botanigard) and PPRI 5339 (Velifer® ES) and a wild strain (AP0101) isolated from Achaia, Greece. The three strains were investigated in the field for their endophytic effects on melon Cucumis melo (Cucurbitales: Cucurbitaceae) and strawberry Fragaria sp. (Rosales: Rosaceae) plants and in particular for their ability to colonize plant tissues, control infestations of sucking insects Aphis gossypii (Hemiptera: Aphididae), Chaetosiphon fragaefolii (Hemiptera: Aphididae) and Frankliniella occidentalis (Thysanoptera: Thripidae), and improve plant growth parameters (plant height, number of flowers and fruits). All experimental fungal strains successfully colonized both plants. A significant decrease in the aphid and thrip populations was observed in the treated plants compared to the untreated control. As for plant growth, the number of flowers and fruits was significantly increased in plants treated with B. bassiana strains AP0101 and PPRI 5339. Our results clearly indicate that fungal endophytes can efficiently act as dual action agents demonstrating both insecticidal and growth-promoting effects.
