“…This significance indicates the existence of genetic variability among the tested genitors, a fact of importance in determining the estimates of the genetic control of these traits. Considering this, there are many studies reporting the effect of zingiberene on oviposition, preference and even the survival of arthropod pests (Ecole, Picanço, Moreira, & Magalhães, 2000;Maluf et al, 2001;Azevedo, Faria, Maluf, Oliveira, & Freitas, 2003;Gonçalves et al, 2006;Silva et al, 2009). …”

“…After collecting the material was added 2 mL of hexane to each tube, then homogenizing it in a tube shaker (model AP56 Phoenix® vortex-type) for 40 seconds, to promote the extraction of zingiberene. After stirring, the leaf disks were removed and the extracts were subjected to reading absorbance at UV-visible spectrophotometer device (Evolution 300, Thermo Scientific) at a wavelength of 270 nm (Silverstein, Bassler, & Morrill, 1994;Maluf, Campos, & Cardoso, 2001). …”

The zingiberene is a sesquiterpene that is present in tomato leaves. This compound is known to promote resistance to pests and diseases. The Brazil has a germplasm bank of vegetable at Universidade Federal de Viçosa (HGB-UFV) crops with over 8 million accesses. One technique that helps in the choice of progenitors with favorable concentrations of zingiberene is the diallel crosses. The diallel crosses allow the estimation of general combining ability (GCA) and specific combining ability (SCA). Thus, the aim of this study was to find out tomato hybrids with high zingiberene concentrations. The genitors were divided into two contrasting groups for resistance to pests. The characterization and quantification spectrophotometric of zingiberene was performed, obtaining absorbance values at 270 nm. To determine the content of zingiberene in hybrids those were coming from the diallel cross. The analysis from the spectrophotometric method was performed. The estimates of GCA and SCA of these hybrids at combinations HGB 2119 x LA716, HGB 2119 x PI 12786, HGB 2214 x HGB 674, HGB 2064 x HGB 674, HGB 2214 x PI 127826, HGB 985 x LA 716 and Santa Clara x HGB 674 have high potential in tomato plant breeding aiming of resistance to pests and diseases.

O objetivo deste trabalho foi avaliar a resistência ao pulgão Myzus persicae em genótipos de tomateiro com altos teores foliares de aleloquímicos. Para tanto, foi realizado um teste de antibiose e dois testes de não preferência, um com pulgões alados e o outro com pulgões ápteros. Os genótipos utilizados foram as linhagens TOM-687 e TOM-688, ricas em acilaçúcares; ZGB-703 e ZGB-704, ricas em zingibereno; BPX-365G-899-07-04-02 e BPX-367E-238-02, ricas em 2-tridecanona; e dois híbridos comerciais usados como testemunhas, Débora Max e Bravo F1 que apresentam baixos teores dessas substâncias. Observou-se aumento do período ninfal dos insetos mantidos sobre os genótipos com altos teores de acilaçúcares, e diminuição do período reprodutivo, da longevidade e da produção de ninfas para pulgões mantidos sobre os genótipos com altos teores de acilaçúcares ou 2-tridecanona. Nos testes de não preferência não ocorreram diferenças significativas entre os genótipos. Conclui-se que os genótipos com altos teores de acilaçúcares ou 2-tridecanona possuem resistência do tipo antibiose a M. persicae.

“…Acylsugar is the main allelochemical produced by S. pennellii, whereas S. habrochaites produces two allelochemicals, 2-tridecanone and zingiberene (Maluf et al, 2001;Azevedo et al, 2003;Simmons and Gurr, 2005;Lucini et al, 2015). However, other tomato genotypes may also be resistant to pests, such as the cultivated variety Solanum lycopersicon var.…”

ABSTRACT. Several studies have been conducted on resistance sources to improve the genetic resistance of farm-grown tomatoes to arthropod pests, including phytophagous mites. In the present study, we evaluate the behavior of the two-spotted spider mite on different cherry tomato accessions to identify possible sources of resistance (repellent effect) to this pest. Sixty-four accessions of cherry tomatoes, Solanum lycopersicum var. cerasiforme (Dunal), were tested. In addition, a commercial cultivar of cherry tomato cv. Sweet Grape (susceptible pattern) and the wild tomato accession Solanum pennellii Correll LA-716 (multiple pest resistance) were evaluated as well. The distance traveled by mites on the leaflet surface over time varied largely among cherry tomato accessions. The wild genotype, S. pennellii LA-716, showed the smallest traveled distance on the leaflet surface (0.8 to 1.1 mm over time), and the variety cv. Sweet Grape was one of the genotypes with highest traveled distance (16.2 to 16.4 mm over time). The cherry tomato accessions 2298-42, RVTC-03, and 6889-53 showed a decrease in the traveled distance by mites over time, similar to that as observed in the wild tomato accession LA716. These accessions showed mite repellence levels similar to those of the wild genotype and may, therefore, be good candidates for breeding programs dealing with resistance to mites.
