“…Similar results as indirect selection were found by Oliveira et al (2012), selected genotypes with the highest trichome density and found levels of resistance to the moth Tuta absoluta that were much higher than those exhibited by susceptible controls, and treatment BPX-367D-238-02 was particularly effective. Maluf et al (2007) found similar results of indirect selection for resistance to the red spider mite T. urticae.…”

In Brazil, the tomato is cultivated in almost all geographic regions even though its yield is significantly reduced by pests and diseases. Among these pests and diseases, whitefly is a major problem that causes direct and indirect damage due to its role in transmission of geminiviruses. The aim of the present study was to compare the degree of resistance to the silverleaf whitefly of tomato plant lines rich in acyl sugars (AS), zingiberene (ZGB), and 2-tridecanone (2-TD) and to establish whether selection for strains with higher densities of glandular trichomes promotes sufficient resistance to this insect pest. The investigated lines were developed by performing back-crossings in tomato (Solanum lycopersicum) from the interspecific crossing of S. lycopersicum x S. habrochaites var. glabratum 'PI 134417'. Lines rich in AS, ZGB, and 2-TD were tested for their levels of resistance to B. tabaci biotype B. Two tomato plant lines (TOM-584 and TOM-679) with normal AS levels and one wild specimen (PI 134417) with high 2-TD content were used as controls. TOM-687, ZGB-703, and TOM-622 were less preferred by B. tabaci for oviposition, and nymphs exhibited a poorer survival rate on those plant lines than on the susceptible controls, TOM-584 and TOM-679. Allelochemicalrich lines exhibited pest resistance, whereas the controls did not, and the allelochemical-rich lines did not differ significantly from each other in the level of resistance. The results show that the development of tomato plant lines rich in 2-TD, ZGB and AS is an effective option for indirect selection for resistance to B. tabaci biotype B. All lines selected based on high trichome density except for BPX-365F-751-05-01-03 exhibited fewer nymphs than the susceptible controls, indicating that selection for more glandular trichomes was generally effective in promoting increased resistance to the silverleaf white flay.Index terms: Solanum lycopersicum, 2-tridecanone, zingiberene, acyl sugars, indirect selection. RESUMONo Brasil, o tomate é cultivado em praticamente todas as regiões, embora seu rendimento seja reduzido por pragas e doenças. A mosca-branca, comumente presente, causa danos diretos e indiretos, devido à transmissão de geminiviros. O objetivo do presente trabalho foi comparar o grau de resistência à mosca branca de linhagens de tomateiro ricas em acilaçúcares (AA), zingibereno (ZGB) e 2-tridecanona (2-TD) e verificar se a seleção de linhagens com base em tricomas glandulares é efetiva no sentido de promover níveis satisfatórios de resistência. Essas linhagens foram obtidas através de retrocruzamentos em tomateiro Solanum lycopersicum, a partir do cruzamento interespecífico S. lycopersicum x S. habrochaites var. glabratum 'PI 1344171'. Linhagens ricas em AA , ZGB e 2-TD foram testadas para níveis de resistência. Duas linhagens de tomateiro (TOM-584 e TOM-679), com nível normal de AA, e o acesso selvagem (PI 134417), alto teor de 2-TD, foram utilizados como testemunhas. TOM-687, ZGB-703 e TOM-622 mostraram diminuições na ovoposição e na contage...

“…Tomato leaf has volatile compounds such as terpenoid that attracts mated females for oviposition. Plant cultivars, rich in 2-tridecane or zingiberene that are chemicals used to give tomato resistance against beet armyworm are not preferred for oviposition by T. absoluta (De Oliveira et al, 2012). However, plants with the absence or less content of terpenes that is herbivores repellent compound are preferable to T. absoluta oviposition (Proffit et al, 2011;Shehata et al, 2016).…”

“…This includes, cultural control measures (crop rotation, selective removal and destruction of infested plant material) (Korycinska et al, 2009), using natural enemies (parasitoids, predators, entomopathogens and nematodes) (Desneux et al, 2010;Urbaneja et al, 2012), botanicals and production of resistant tomato cultivar varieties (De Oliveira et al, 2012). The integration of these methods with each other and if possible with less environmental hazardous insecticides are important to control T. absoluta without disturbing ecological world.…”

“…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). The resistance of tomato strains rich in 2-tridecanone (2-TD), zingiberene (ZGB), and acyl sugars (AA) to the tomato moth, T. absoluta showed significant reduction on evaluated characteristics, such as oviposition rate, severity of damage to the plants, injuries to the leaflets, and the percentage of leaflets attacked (De Oliveira et al, 2012).…”

Continue climatic changes in the world enhance the emergence of invasive agricultural insect pests.Tuta absoluta is one of the most devastating tomato leafminer and it spreads extensively in almost all parts of the world. It is a serious threat for tomato production and it results in highest damage. T. absoluta has fast growth rate with developmental stages of egg, larvae, pupa, and adult and it adapts to different environmental conditions. A larva is the most destructive one that consumes preferably leaves, stems and fruits of the tomato plant by hiding within mesophyll of the plant tissues. Although different environmentally hazardous pesticides are used against T. absoluta, none of the insecticides give full control due to the resistance development. This problem calls an urgent search for eco-friendly alternatives to control this invasive insect. Recent investigations are focused on different environmental friendly approaches that inclusively termed as IPM strategies. These are cultural practices, biopesticides, and biological using parasitoids, predators, microbial cells, microbial products, RNAi, inheritance sterility development in insect and pest resistant plant cultivar production are considered as promising alternatives to control T. absoluta. Therefore, this review briefly describes the current status of these methods used to design suitable and sustainable management strategies against T. absoluta.

BACKGROUND: Host plant resistance plays an important role in integrated pest management programs. Crop resistance assessments commonly focus on only a single dependent variable, such as larval survival/plant damage, which limits the ability to appreciate the impact of host plants on pest populations in the full sense. Therefore, we performed life-table analyses for tomato leaf miner Tuta absoluta, on 19 Solanum lycopersicum genotypes and a wild Solanum habrochaites accession. These analyses assess the ability of the pest to attain a high population density on different tomato genotypes. Based on the resulting ranking of tomato resistance at the vegetative stage (45-day-old plants), we tested the resistance of six selected genotypes at the reproductive stage (4-month-old plants). RESULTS: T. absoluta performance was significantly inferior on vegetative-stage S. habrochaites plants (LA 1777); time taken for the first instars to mine the leaves (5 ± 0.14 days), development time of early-and late-stage larvae (8.8 ± 0.2 and 4.2 ± 0.2 days, respectively), pupal period (11.2 ± 0.58 days), and total developmental time (29.4 ± 0.83 days) were significantly longer, fecundity was significantly lower (18.66 ± 7.24 days), and the highest total mortality (63.33%) also recorded compared with other genotypes, resulting in the lowest net reproductive rate (R 0 ) (11.20 ± 2.51). For the six selected genotypes, the ranking of plant resistance did not change between plants at the vegetative and reproductive stages.CONCLUSION: This study suggested that of 20 screened tomato genotypes, LA 1777 and EC-620343 are the least suitable hosts for T. absoluta to establish fast-growing populations, and thus can be employed in integrated T. absoluta management.
