Tomato plants are highly susceptible to pests. Among the control methods, genetic improvement with introgression of resistance genes from wild accessions into commercial tomato lines is the best alternative for an integrated pest management (IPM). Thus, the objective of this study was to select tomato genotypes in advanced populations (F2BC3), with higher levels of acylsugar content, greater recurrent parent genome recovery, and resistance to Tetranychus urticae and Bemisia tabaci inherited from Solanum pennellii. For pest resistance, bioassays were assessed: nine high-acylsugar genotypes, four low-acylsugar genotypes, and the parents, Solanum lycopersicum or ‘Redenção’, and Solanum pennellii LA-716. Glandular and non-glandular trichomes were quantified. A negative correlation was measured between acylsugar content in the leaflets and pest behavior. Pest resistance was found in the selected F2BC3 genotypes with high-acylsugar content, indicating that this allelochemical was efficient in controlling the arthropod pests.

“…S. pennellii was obtained from the University of California in 1997, and plants have been maintained by the coordinator of the research group of this breeding program. After obtaining the F 1 hybrids, successive backcrosses and selections were conducted until obtaining the F 2 BC 2 genotypes [ 15 ].…”

“…This indicates an interweaving of plants' mechanisms of defence, as the trichomes not only provide a physical barrier against herbivory attack, but they also produce chemicals that are deterrents to insect oviposition and feeding.

“…Therefore, resistant cultivars and plant-derived products depicting pest control potential should be further investigated for a fast introduction in the agricultural production daily routine. All current tomato varieties are attacked by the pest, but some cultivars tend to be less attractive (Proffit et al, 2011;Cherif and Verheggen, 2019) and some new hybrids under testing demonstrate potential to advance in the tomato breeding with resistance to tomato leafminer (Gharekhani and Salek-Ebrahimi, 2014;Ghaderi et al, 2017;Ataide et al, 2017;Sohrabi et al, 2017;Dias et al, 2019). The present paper summarizes the current knowledge regarding the efforts to obtain tomato and other solanaceous resistant lines based on characteristics found in different wild relatives of tomatoes and compiles references regarding other effective phytochemicals that could be alternatively used for T. absoluta control.…”

For integrated pest management (IPM) and organic farming, breeding resistant varieties is one of the most eco-friendly approaches, that goes along botanicals and other different cultural practices, as the use of companion plants. Among the many pest species that invaded the whole world in the last decades, one of the most frightening is the tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), a devastating pest of cultivated tomato worldwide. Tomato is one of the most important agricultural commodities, including the main mean of subsistence in many countries from Africa and middle East. As chemical pesticides failed to control de pest spread and led to many reports of resistant populations, alternative methods for tomato leafminer management must be quickly developed. Many of such alternatives count on a wide range of chemical compounds. The chemical compounds most often responsible for “constitutive resistance”, synthetized by tomato are methyl-ketones (2-tridecanone), sesquiterpenes (zingiberene), and acyl sugars (acylglucose and acylsucrose) while the chemical compounds produced by other plants, used as isolated substances or mixtures, which have antifeedant, growth inhibiting, repellent, and insecticide effects, are azadirachtin, carvacrol, cinnamaldehyde, citronellal, eugenol, linalool, nicotine, pyrethrin, rotenone, thujone, thymol, α-terpineol, 1.8-cineol, etc. Many of them are already commercially available but their efficacy and use differ widely. Therefore, a deeper understanding of the resistance mechanism of solanaceous species related to chemical compounds and substances important for IPM plans developed against T. absoluta is required by the breeding programs.

Among the newly introduced pests of tomato is tomato leaf miner (Tuta absoluta), a ruthless and highly resilient pest with innate destructive capacity [28].Tomato Fruit Borer (Helicoverpa armigera) is the most damaging insect, especially at tomato fruit formation [8,9]. The larval stage is the infective age and it bores and feeds on tomato fruits causing injury.…”

Background: Tomato is an essential and remunerative staple food widely grown and consumed in all parts of Nigeria. The northern parts of the country produce ninety-eighth percent of the tomatoes consumed annually. However, higher percentages of tomatoes produced in these regions are lost due to gaps recorded in its value chain. Principal Findings: Tomato value chain needs to be strengthened from production to processing, preservation and good marketing structure. Challenges bedevilling tomato value chain in Nigeria include poor accessibility to production inputs such as seeds, nurseries, fertilizers; poor packing systems and transportation problems; marketing challenges and yield reduction caused by a complex of arthropod pests attacking the crop. The major arthropod pests inflicting economic damage on tomato include fruit borer, whitefly, aphid, thrips and leaf miners. Interventions: Considering the Nigerian Government’s recent interventions: “close border”, increased tariffs on the importation, and different incentives such as “tax holiday” and introduction of zero percent import duty on greenhouse equipment, soft loans through Bank of Agriculture as well as a national collaborative effort against the menace of tomato leaf miner (Tuta absoluta) invasion; How much of these interjectory efforts have translated to the realization of national self-sufficiency in the tomato value chain? Conclusion: This paper highlights the general introduction of tomato, its botany, nutritional benefits, tomato value chain in Nigeria, Nigerian government interventions towards its sustainability with particular focus on research cocktails at combating the problems of arthropod pests on the tomato to identify the probable critical solutions to these harmful pests.
