Abstract: RESUMOUma das estratégias do melhoramento do tomateiro, no Brasil, visando à resistência a pragas, tem sido a utilização de aleloquímicos presentes nos folíolos. Objetivou-se no presente trabalho, estudar os níveis de resistência a dois artrópodos-pragas [traça do tomateiro (Tuta absoluta) e ácaros (Tetranychus evansi)], em genótipos previamente selecionados com base apenas no seu teor foliar de acilaçúcares. Foram selecionadas 11 plantas contrastantes quanto aos níveis de acilaçúcares nos folíolos, de uma pop… Show more

“…The distance covered by the spider mites, on the leaflets of the wild accession, S. pennellii, during the evaluation time (5, 10, 15, and 20 min), was shorter (<0.2 cm) than in all other treatments, indicating repellence. These results corroborate with many studies that evaluated the mite repellence on tomato genotypes of Santa Cruz type (Pereira et al, 2008;Maluf et al, 2007Maluf et al, , 2010. On the other hand, the higher distances covered were obtained on the check treatments, cv.…”

“…Many authors have studied the mite behavior and have done associations between the acylsugar content and the repellence to the two-spotted spider mites. The possibility of obtaining tomato lines and hybrids of Santa Cruz type rich in acylsugar on the leaflets and resistant to the mite has already been verified (Pereira et al, 2008;Maluf et al, 2007Maluf et al, , 2010. In this study, the mini tomato genotypes, UFU-22-F 2 BC 1 #4, UFU-22-F 2 BC 1 #5, UFU-22-F 2 BC 1 #6, UFU-22-F 2 BC 1 #7, UFU-22-F 2 BC 1 #9, UFU-22-F 2 BC 1 #10, UFU-73-F 2 BC 1 #11, and UFU-73-F 2 BC 1 #12 stood out for having lower distance covered by the mites on the leaflets (Figure 1).…”

“…Accessions of S. pennellii have high levels of resistance to a large number of arthropod pests, including the tomato pinworm (Gonçalves et al, 2006;Saeidi et al, 2007;Pereira et al, 2008;Resende et al, 2006Resende et al, , 2008Resende et al, , 2009Gonçalves Neto et al, 2010). The resistance of S. pennellii has been associated with the presence of allelochemicals called acyl sugars, which are esters of fatty acids.…”

“…Insect resistant cultivar development is considered as Aynalem 19 one of alternative approach than chemical pesticides for obtaining cost-benefit ratio for pest control (Pereira et al, 2008;Gonçalves et al, 2010;Maluf et al, 2010). In Brazil, tomato improvement was practiced to obtain pestresistant cultivars by incorporating the alleles for resistance present in wild plants for commercialization and produce the allele-chemicals associated with resistance (Silva et al, 2009;Gonçalves et al, 2010;Maluf et al, 2010).…”

Three types of allele-chemicals (acylsugars, zingiberene, and 2-tridecanone) have been associated as resistant to T. absoluta (Pereira et al, 2008;Silva et al, 2009;Maluf et al, 2010). However, studies comparing levels of pest resistance among strains rich in different allele-chemicals are few (De Oliveira et al, 2012).…”
