“…Researchers have associated high ZGB levels with resistance to the tomato moth (Tuta absoluta), which confirms the results found in this study (Azevedo et al, 2003;Silva, 2009;Oliveira et al, 2012). High levels of ZGB are efficient at causing resistance to the tomato moth when compared to genotypes that have low levels of ZGB.…”

ABSTRACT. Obtaining tomato cultivars resistant to pests through interspecific crosses between commercial cultivars and wild accessions is an important tool in integrated pest management. The aim of this study was to select tomato genotypes with high zingiberene (ZGB) levels that are resistant to the South American tomato moth (Tuta absoluta Meyrick) and to estimate genetic parameters of ZGB inheritance from the interspecific cross Solanum lycopersicum cultivar 'Redenção' x Solanum habrochaites var. hirsutum (PI-127826 accession). F 2 plants with different ZGB contents were selected and submitted to a tomato moth resistance test. ZGB content exhibits high broad sense heritability, with incomplete dominance of lower ZGB content. Furthermore, the level of ZGB in leaflets was estimated to be controlled by two genes. These results show that high ZGB levels are effective at conferring resistance to the South American tomato moth.

“…even though a blend of the two terpenes can be expected, we speculate that curcumene is detected at further distance from the odor source and therefore is most likely more responsible for the deterring effect. The toxicity of zingiberene and curcumene to insects has been shown previously in experiments with essential oils and extracts (Carter et al, 1989;Weston et al, 1989;Eigenbrode et al, 1994;Freitas et al, 2002;de Azevedo et al, 2003). Freitas et al (2002) also showed that there is a positive and heritable relation between tomato foliar zingiberene levels and levels of B. argentifolii infestation.…”

Bemisia tabaci (whitefly) infestations and the subsequent transfer of viruses are the cause of severe losses in crop production and horticultural practice. To improve biological control of B. tabaci, we investigated repellent properties of plant-produced semiochemicals. The mix of headspace volatiles, collected from naturally repellent wild tomato accessions, influenced B. tabaci initial choice behavior, indicating a role for plant semiochemicals in locating host plants. A collection of wild tomato accessions and introgression lines (Solanum pennellii LA716 3 Solanum lycopersicum 'Moneyberg') were extensively screened for attractiveness to B. tabaci, and their headspace profiles were determined by means of gas chromatography-mass spectrometry. Correlation analysis revealed that several terpenoids were putatively involved in tomato-whitefly interactions. Several of these candidate compounds conferred repellence to otherwise attractive tomato plants when applied to the plant's branches on paper cards. The sesquiterpenes zingiberene and curcumene and the monoterpenes p-cymene, a-terpinene, and a-phellandrene had the strongest effects in free-choice bioassays. These terpenes also elicited a response of receptors on the insect's antennae as determined by electroantennography. Conversely, the monoterpene b-myrcene showed no activity in both assays. B. tabaci apparently uses, besides visual cues, specific plant volatile cues for the initial selection of a host. Altering whitefly choice behavior by manipulation of the terpenoid composition of the host headspace may therefore be feasible.

“…Resende et al (2006) and Azevedo et al (2003) verified reduction in the oviposition of Tuta absoluta in genotypes with high contents of acylsugars and Resende et al (2002b) reported the antibiosis effect on Bemisia argentifolli. In the mite of the genus Tetranychus the acylsugars act as repellent, probably due to their toxic activity .…”

The Lycopersicon pennellii accession LA716 has been used as a source of arthropod pest resistance in tomato breeding programs due the high contents of acylsugars presents in its leaflets. We investigated the relationship between high foliar acylsugar contents and repellence to spider mite Tetranychus evansi in plants with contrasting acylsugar levels, selected from F 2 and BC 1 F 2 (= F 2 of the first backcross towards L. esculentum) generations derived from the interespecific cross L. esculentum 'TOM-584' × L. pennellii LA716. Mite resistance was assessed by a repellence test. Plants selected for high levels of acylsugars in leaflets had mite repellence levels similar to that of LA716. The high correlation confirmed the association between high acylsugar levels and mite repellence.

Foi verificada a correlação entre o teor de acilaçúcares em folíolos de tomateiros e a repelência ao ácaro Tetranychus evansi Baker & Pritchard. Foram selecionadas plantas contrastantes quanto aos níveis de acilaçúcares nos folíolos de populações F 2 e F 2 RC 1 (= F 2 do primeiro retrocruzamento para Lycopersicon esculentum) do cruzamento interespecífico de L. esculentum TOM 584 (baixo teor de acilaçúcares) e L. pennellii LA 716 (alto teor). Foi realizado um teste de repelência ao ácaro T. evansi, tomando por base a distância percorrida pelos ácaros nos folíolos. Os genótipos selecionados para alto teor de acilaçúcares, em média, foram responsáveis por reduções significativas nas distâncias percorridas pelos ácaros sobre a superfície do folíolo. A repelência ao ácaro T. evansi exercida pelas plantas selecionadas para alto teor de acilaçúcares deu-se de forma semelhante àquela conferida pelo genitor LA-716. As magnitudes das correlações encontradas confirmam a associação entre altos teores do aleloquímico e a repelência ao ácaro.
