“…The significant, negative correlations we found between AS levels and whitefly oviposition rates and number of nymphs confirm the importance of ASs in reducing attacks by this pest species. Dias et al (2013) found significant, negative correlations between AS content and the number of T. absoluta eggs and larvae on tomato leaflets. However, Resende et al (2009) found no significant correlation between AS content and whitefly oviposition rates, but did find a significant negative correlation between AS levels and the number of nymphs.…”

“…Baier et al (2015) previously selected these cultivars for resistance to spider mites (Tetranychus urticae), and by Dias et al (2013) for resistance to the tomato pinworm (Tuta absoluta); these cultivars were cloned and backcrossed with the recurrent parent, Redenção. The cloning was performed using axillary buds taken from each genotype, which were transplanted into 60-cell polystyrene trays and identified.…”

“…Therefore, alternative methods of controlling B. tabaci biotype B are required, in order to reduce the amount of chemicals used in the management of arthropod pests (Sayeda et al, 2009). The use of tomato genotypes that are resistant to arthropod pests has shown promising results (Toscano et al, 2002;Fancelli et al, 2003;Maluf et al, 2010;Dias et al, 2013;Lucini et al, 2015). Varietal resistance is a viable alternative within an integrated pest management strategy, because the resistance levels exhibited by commercial cultivars, particularly those that are cultivated for industrial processing, are inadequate.…”

ABSTRACT. The wild tomato, Solanum pennellii, is an important source of resistance genes against tomato pests. This resistance is due to the presence of acyl sugars (AS), which are allelochemicals that have negative effects on arthropod pests. There are no commercially available tomato cultivars that exhibit significant levels of resistance to arthropod pests. Therefore, this study evaluated resistance to whitefly (Bemisia tabaci) in F 2 and F 2 RC 1 tomato genotypes with high AS levels from a cross between Solanum lycopersicum 'Redenção' and the S. pennellii accession, LA-716. Plants were exposed to B. tabaci biotype B at the pre-flowering stage. In both generations, there were significant, negative correlations between AS content and oviposition preference and nymph development. Whitefly exhibited a lower preference for oviposition and produced fewer nymphs in genotypes with high AS levels and the wild parent S. pennellii than in the low AS-level genotypes and Redenção cultivar, demonstrating that the breeding program was effective in transferring resistance to the F 2 and F 2 RC 1 generations. RVTA-2010-pl#31 and RVTA-2010-pl#94 are promising genotypes that produced materials with high AS levels in the F 2 RC 1 generation (RVTA-2010-31-pl#177 and RVTA-2010-94-pl#381).

“…Some wild species of tomato have physical and chemical factors associated with pest resistance; those most studied include glandular trichomes and allelochemicals, which that are natural chemical compounds produced and exudated by the trichomes themselves. These factors have been associated with obstruction to feeding, development, and reproduction of arthropod pests (Dias, Resende, Faria, Camargo, & Lima, 2013;Silva et al, 2016).…”

The aim of this study was to verify the resistance of tomato genotypes (crossed with Solanum galapagense) to the green peach aphid, Myzus persicae, and the association of this resistance with glandular trichomes. Leaf trichomes were quantified for seven F2 genotypes of the BPX-486 population derived from crossing S. lycopersicum ‘TOM-684’ and S. galapagense accession ‘LA-1401’, for the commercial controls ‘TOM-584’ and ‘Santa Clara’, and for the accession ‘LA-1401’. After this evaluation, the genotypes were subjected to two nonpreference resistance tests of the green peach aphid in the laboratory, one with choice and the other without choice. Five genotypes (BPX-486-17, BPX-486-62, BPX-486-10, BPX-486-46, and BPX-486-08) and the accession LA-1401 exhibited a high density of type IV glandular trichomes and a lower mean number of nymphs and adults of M. persicae than two genotypes (BPX-486-313 and BPX-486-383) and the controls with a low density of glandular trichomes, in all the evaluations of both tests. Significant negative correlations between the density of type IV glandular trichomes of the tomato genotypes and the preference of M. persicae were found, which confirms the association between this type of glandular trichome and resistance to M. persicae in tomato genotypes.

“…With increased demand for tomato based products by the consumer, as well as increased demand for high quality products with low agrochemical indexes, alternative methods of control have been used in an attempt to reduce the use of chemical products; this includes the use of resistant genotypes, which have shown promise in the fight against arthropod pests (Resende et al, 2009;Silva et al, 2009;Oliveira et al, 2012;Dias et al, 2013;Neiva et al, 2013;Lucini et al, 2015).…”

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.
