“…The genitors were divided into two contrasting groups for resistance to pests. The first group was composed of five tomato accessions with desirable agronomic traits and the second group with six tomato accessions with traits of resistance to pests (Leite, Picanço, Guedes, & Gusmão, 1998;Marim et al, 2004;Resende et al, 2008;Oliveira et al, 2009;Antônio, Silva, Picanço, Santos, & Fernandes, 2011).…”

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.

“…Tomato plants ( Solanum lycopersicum ) possess morphological structures and phytochemicals that act as natural defenses against herbivorous insects. In tomatoes, the plant defenses consist of trichomes, toxins, anti-nutritive defensive proteins, protease inhibitors and cellular structures [ 12 ], [ 13 ]. The quantities in which these defenses are present vary among the different plant parts in tomatoes [ 13 – 15 ].…”

Is the Performance of a Specialist Herbivore Affected by Female Choices and the Adaptability of the Offspring?

The performance of herbivorous insects is related to the locations of defenses and nutrients found in the different plant organs on which they feed. In this context, the females of herbivorous insect species select certain parts of the plant where their offspring can develop well. In addition, their offspring can adapt to plant defenses. A system where these ecological relationships can be studied occurs in the specialist herbivore, Tuta absoluta, on tomato plants. In our experiments we evaluated: (i) the performance of the herbivore T. absoluta in relation to the tomato plant parts on which their offspring had fed, (ii) the spatial distribution of the insect stages on the plant canopy and (iii) the larval resistance to starvation and their walking speed at different instar stages. We found that the T. absoluta females preferred to lay their eggs in the tomato plant parts where their offspring had greater chances of success. We verified that the T. absoluta females laid their eggs on both sides of the leaves to better exploit resources. We also observed that the older larvae (3rd and 4th instars) moved to the most nutritious parts of the plant, thus increasing their performance. The T. absoluta females and offspring (larvae) were capable of identifying plant sites where their chances of better performance were higher. Additionally, their offspring (larvae) spread across the plant to better exploit the available plant nutrients. These behavioral strategies of T. absoluta facilitate improvement in their performance after acquiring better resources, which help reduce their mortality by preventing the stimulation of plant defense compounds and the action of natural enemies.

“…Interestingly, the survival rate of the immature stages was higher on potato than on tomato plants. Tomato plants are rich in trichomes, anti-feedant proteins, toxins and protease inhibitors that protect them against pest attack 20 , 34 , 35 . The movement of early larval instar T. absoluta on the surface of tomato plants is made more difficult because of their small size and the presence of protective barriers (trichomes and hairs) on the leaf surface 36 , 37 .…”

The tomato pinworm Tuta absoluta (Lepidoptera: Gelechuidae) is native to South America and has now become the main tomato pest in Europe, Africa and Asia. The wide range of host plants attacked by this pest has been reported as one of the main reasons for the success of this important insect species. However, the information currently available on the biological performance of T. absoluta on Solanaceae has been obtained from a limited number of host species. The Solanaceae family is composed of thousands of species, many of which are potential hosts for T. absoluta. Our results showed that the highest oviposition rates occurred on cultivated tomato plants, potato and wild tomato. The lowest rates occurred on “gilo”, “jurubeba”, green pepper and pepper. The highest survival rates of the immature stages occurred on potato and the lowest on pepper, green pepper and “jurubeba”. Female fertility, following infestation of the different plant species, was highest for insects that developed on tomato or potato and the lowest rates were seen on American black nightshade. The net reproductive rate and the intrinsic growth rate were highest on potato and tomato. Cluster analysis grouped tomato and potato as highly susceptible to attack, American black nightshade, juá, eggplant, gilo and wild tomato as moderately susceptible, whilst pepper, green pepper and jurubeba were categorized as resistant to T. absoluta. These results clearly demonstrate that the choice of solanaceous host plant species has a direct impact on the fitness parameters of the tomato pinworm as well as survival potential, dispersion and establishment at new sites. These results are important for the planning of integrated pest management strategies.
