Tomato Breeding for Sustainable Crop Systems: High Levels of Zingiberene Providing Resistance to Multiple Arthropods

Abstract

In sustainable cropping systems, the management of herbivorous arthropods is a challenge for the high performance of the tomato crop. One way to reduce the damage caused by these pests is the use of resistant cultivars within a sustainable integrated management system. The host selection of Tetranychus urticae, Bemisia tabaci, and Tuta absoluta was evaluated, characterizing their preference among the tomato genotypes RVTZ2011-79-503-143, RVTZ2011-79-335-164, RVTZ2011-79-185-250 (high zingiberene content—HZC), and RVTZ2011-79-117-273 (low zingiberene content—LZC). Such genotypes were selected in the F2BC2 generation (the F2 generation of the 2th backcross towards Solanum lycopersicum after the inicial interspecific cross S. lycopersicum × S. habrochaites var. hirsutum), resulting from crossing Solanum habrochaites var. hirsutum PI-127826 (HZC and resistant to mites) and the commercial cv. Redenção (S. lycopersicum) (LZC and susceptible to mites). In choice and no-choice bioassays by T. urticae, and in choice bioassays by B. tabaci and T. absoluta, arthropods preferred to stay and oviposit in an LZC genotype. In contrast, genotypes with HZC showed repellency to pests and induced a non-preference for oviposition. The F2BC2 genotypes selected for HZC are considered sources of resistance genes to these pests for tomato breeding programs, and therefore have excellent potential for sustainable cropping systems. These results represent an advance in obtaining tomato genetic materials which can be used in sustainable production systems with less loss from pests.

Relationship between salicylic acid and resistance to mite in strawberry

“…Glandular trichomes may also contain defensive substances that constitute a firstline chemical barrier against infesting arthropods. The sesquiterpenes Zingiberene, present in some tomato glandular trichomes, was associated with TSSM nymph mortality and diminishing fecundity (Oliveira et al, 2018;Oliveira et al, 2020). The strong correlation observed between the density of non-glandular trichomes and the oviposition and survival of adults are presumably related to the dysfunction caused by these structures to the movement and permanence of the mite on the surface of the leaflet (Resende et al, 2020).…”

Insights on solanaceous resistance against tomato leafminer (Tuta absoluta), with emphasis on chemical compounds useful in integrated pest management

“…Zingiberene has been shown to confer resistance to insect pests upon tomatoes (ccc). Genotypes with high zingiberene content demonstrated lower appeal for T. absoluta egg deposition (de Oliveira et al, 2020). In addition, genotypes exhibiting high contents in both zingiberene and acyl sugars, showed greater resistance than genotypes accumulating only one of these chemicals, indicating a synergistic effect between zingiberene and acyl sugars (Maluf et al, 2010).…”

“…In addition, genotypes exhibiting high contents in both zingiberene and acyl sugars, showed greater resistance than genotypes accumulating only one of these chemicals, indicating a synergistic effect between zingiberene and acyl sugars (Maluf et al, 2010). Zingiberene content has high heritability, (<80%), its production being controlled by two genes with incomplete dominance (de Oliveira et al, 2020).…”

“…The development of resistant cultivars is critical for a transition to a sustainable system. The host selection of Tetranychus urticae, Bemisia tabaci, and Tuta absoluta was evaluated by de Oliveira et al [5], characterizing their preference for high zingiberene content (HZC) or low zingiberene content (LZC) tomato leaves. Tomato genotypes with HZC showed repellency to pests and induced a nonpreference for oviposition.…”
