In this study, the effects of five wild tomato species (Solanum chilense, Solanum corneliomulleri, Solanum neorickii, Solanum huaylesense and Solanum pennellii) on the life table parameters of Tuta absoluta were determined for the first time, and the larval development time, lifespan, pupal period, fecundity, and female/male longevity were also estimated. According to the data obtained from the study, S. chilense was determined as the most suitable species for the development of T. absoluta. Among the wild tomato species, S. corneliomulleri and S. neorickii were determined as the most effective hosts against T. absoluta in terms of the intrinsic rate of increase, net reproductive rate, mean generation time, gross reproduction rate, population doubling time, and finite rate of increase than the other species. These two species were also effective against the pest on the egg, larval development, total longevity, and fecundity. According to these results, S. corneliomulleri and S. neorickii are viable candidates for the development of new resistant tomato genotypes to T. absoluta.

“…Another study determined the level of resistance among tomato cultivars based on the antibiosis (by observing larval survival and weight of male, females pupae) and antixenosis (by observing oviposition) criteria (Vitta et al, 2016). Among the wild varieties evaluated, S. habrochaites (RCAT030597) genotype was found resistant based on the antibiosis with lower larval survival.…”

D uring the recent years, tomato leafminer Tuta absoluta has been considered as one of the key pest of tomato outside its native range of South American countries. It has been reported to be available in tomato growing areas (either cultivated or greenhouse) of European, South American and Asian Abstract | Tomato leafminer, Tuta absoluta has emerged as a serious oligophagous pest of tomatoes and other allied vegetables. It has recently been reported from Sindh, Pakistan, where studies on its biology and management are lacking. Therefore, studies were conducted to determine the relative resistance of widely grown hybrid (Rota F1, Early King, G1612, NAGA F1 and T-1057) and local tomato varieties (Desi Local and Shimlo) of Sindh, Pakistan against T. absoluta. All the varieties grown with standard agronomic practices as data on infestation of T. absoluta was taken weekly since the fifteen days of tomato transplanting depending on its characteristic damage symptoms. Both local tomato varieties were found significantly more susceptible than hybrid varieties that also differ in their relative resistance against T. absoluta. Overall, significantly the highest T. absoluta infestation on tomato leaves and fruits was recorded on Desi local (27.19±9.10 and 9.10±0.44%) and Shimlo (26.47±8.76 and 8.76±0.43%) varieties, whereas T1057 (9.70±3.54 and 3.54±0.19%) suffered the lowest infestation. Among hybrid varieties, the highest T. absoluta infestation on leaves and fruits was recorded on Rota F1 (21.22±7.07 and 7.07±0.33%) variety. A significant effect of T. absoluta infestation was also recorded on tomato yield of various varieties as the highest yield (735.20±9.49 maunds/acre) was recorded for T1057 variety, followed by Early King (676.40±8.21 maunds/acre). The lowest yield was observed in Desi Local (407.60±7.03 maunds/acre) and Shimlo (412.60±8.60 maunds/acre). Therefore, further studies should be planned to evaluate the mechanism of resistance among different tomato varieties against T. absoluta so that better breeding strategies could be employed to develop more resilient varieties with good yield potential.

“…This higher preference for oviposition on tomato and potato has been explained in terms of the volatile organic compounds that deter oviposition on eggplant and the presence of higher amounts of terpenes in those plant species compared to eggplant that serve as oviposition stimulants [ 46 ]. In addition, the lower suitability of eggplant for infestation by T. absoluta has been explained in terms of the presence of 77 secondary metabolites that increase in abundance following infestations that are believed to deter feeding by T. absoluta [ 47 ]. Thus, the lower feeding damage by T. absoluta on eggplant is due to antixenosis (defined as the non-preference of insect pests for plants that lack stimuli for feeding or oviposition) and antibiosis (defined as adverse physiological responses experienced by the insect pest following the ingestion of plant material) resistance.…”

Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) is a destructive insect pest toward crops and belongs to the Solanaceae family. Since it was first recorded in South Africa in 2016, the pest has spread extensively and caused tremendous damage to field and tunnel-grown tomato crops. This study aimed to investigate how T. absoluta affects the growth and physiology of three Solanaceae plant species: tomato, potato, and eggplant. These three crops were infested with L1 instar larvae, and their growth and physiology were assessed during insect feeding. The damage to the infested tomato host plant was severe, with T. absoluta destroying 100% of the plants. The tomato plants were distorted 15 days after infestation, that is, before the fruit set. For potato, the defoliation was moderate, but the infested plants produced fewer tubers compared to the uninfested host plants. Eggplant had fewer visible signs of feeding, resulting in no significant difference between the infested and uninfested host plants in terms of growth and physiological functions. Infested tomato and potato plants had stagnant growth, fewer and damaged leaves, a reduced chlorophyll content, a reduced photosynthesis rate, a poor transpiration rate, poor water conductance, and poor intercellular carbon dioxide concentrations. This study closes the knowledge gap on the morphological (growth) and physiological responses of different Solanaceae species to T. absoluta infestation, and it also demonstrates the differential risk of T. absoluta infestations in the production of tomato, potato, and eggplant.
