Selection of tomato genotypes for processing with high zingiberene content, resistant to pests

Abstract

Tomato cultivars resistant to arthropod pests are an important tool to reduce the use of pesticides. Resistance sources can be found in wild Solanum species such as S. habrochaites, which shows high levels of zingiberene (ZGB). This study aimed to evaluate the resistance of a tomato F2 progeny to spider mite and whitefly by evaluating the ZGB content, in laboratory, in plants from the F2 population of the interspecific crossing Solanum lycopersicum cultivar Redenção x Solanum habrochaites var. hirsutum (PI-127826), F1 plants, susceptible plants (cultivar Redenção) and plants of the wild species (PI-127826). From the F2 population, six plants with high content and three with low content of ZGB were selected. For evaluating the impact of ZGB on the spider mite behavior, the distance walked by spider mites from a central point was measured on the selected plants and their parents. For whitefly, the number of eggs and nymphs were quantified. Spider mites travelled shorter distances in plants with high ZGB content. Also, the number of whitefly eggs and nymphs was lower in these plants. Higher ZBG contents affected negatively both the spider mite and the whitefly behavior.

Application of Chromatographic and Spectroscopic Methods towards the Quality Assessment of Ginger (Zingiber officinale) Rhizomes from Ecological Plantations

“…In comparison with other previously studied rhizomes cultivated in different areas of the world, Japanese samples of Zingiber officinale may be perceived as rich sources of zingiberene—a strong pesticide [25], geranial—an anti-inflammatory agent [26], and ( E , E )-α-farnesene, known for its antibacterial and antifungal properties [27]. …”

Trichomes and Allelochemicals in Tomato Genotypes Have Antagonistic Effects Upon Behavior and Biology of Tetranychus urticae

“…Redenção and RVTZ-09 (low ZGB content) were the most preferred genotypes by T. urticae . Lima et al (2016) evaluating these same ZGB-rich genotypes observed a strong repellency effect against T. urticae and whitefly Bemisia tabaci (Genn.). The results indicated that non-preference is a mechanism by which ZGB-rich genotypes express resistance to the two-spotted spider mite.…”

“…Plants that produce and release chemical compounds (allelochemicals) affecting arthropod behavior and biology, may express resistance through both antixenosis (non-preference) and/or antibiosis ( War et al, 2012 ). In tomato, resistance has been extensively reported in the literature as mediated by different allelochemicals against arthropod pests such as mites ( Gonçalves et al, 2006 ; Resende et al, 2008 ; Lucini et al, 2015 ; Lima et al, 2016 ), whiteflies ( Freitas et al, 2002 ; Silva et al, 2009 ; Lima et al, 2016 ), and lepidopterans ( Maluf et al, 2010 ; Dias et al, 2013 ; Lima et al, 2015 ).…”

Ginger and Turmeric Essential Oils for Weed Control and Food Crop Protection

“…Zingiberene, the chief component of the Z. officinale essential oil here analyzed, is a monocyclic sesquiterpene hydrocarbon with natural antioxidant and cytotoxic activities: it is capable of protecting against H 2 O 2 -induced cytotoxicity and oxidative DNA damage in neuronal cells [35] as well as inhibiting the growth of lymphocytic cells in a dose-dependent manner [36]. Furthermore, high zingiberene content in tomato plants provides resistance against arthropod pests including spider mite ( Tetranychus urticae ) and whitefly ( Bemisia tabaci ) [37,38]. On the other hand, β-sesquiphelladrene, the main isomer of zingiberene and second main compound in the ginger essential oil here analyzed, has antiviral and antifertility effects [38] as well as anticancer potential by inducing apoptosis through mitochondrial pathways [39].…”
