“…However, due to successful biological control, the pest can be very well managed in Europe (Urbaneja et al 2012). Without control methods, this pest causes yield losses up to 100% and decreases fruit quality in both field and in greenhouse tomato crops (Guilardó n et al 2001;Desneux et al 2010). In Brazil, two other important lepidopteran pests occur in tomato: the tomato fruit borer, Neoleucinodes elegantalis (Guenee) (Lepidoptera: Crambidae) and tomato fruitworm Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae).…”

The tomato borer Tuta absoluta, native to western South America, is an extremely devastating pest in tomato crops in most of South America, Europe and Africa North of the Sahel, causes yield losses up to 100% and decreases fruit quality in open field and greenhouse crops if control methods are not applied. In Brazil two other important lepidopteran pests -Neoleucinodes elegantalis and Helicoverpa zeaoccur in tomato, as well as thrips, whiteflies and aphids. For control of these pests, frequent applications of pesticides of up to 5 times per week are needed, and these resulted in the appearance of resistant populations to a number of active ingredients and decimation of natural enemies. Biological control may offer a better, safer and more sustainable opportunity for pest management. Mirid predatory bugs are currently used with success in southern Europe to control T. absoluta and other pests. In Brazil, four Hemipteran predatory bugs, not yet known to attack T. absoluta, were found to successfully prey on eggs and larvae of this pest. The first results on their predation capacity, development, survival and reproduction on T. absoluta on tomato plants are presented.

“…In S. pennellii accession 'LA 716', the main AA is 2,3,4-tri-O-acyl-glucose. Its resistance character is presumably due to the fact that it confers a sticky appearance to leaf surfaces, which acts as a natural trap, avoiding pest insect oviposition, feeding or even causing deleterious effects on their development [13,46,47].…”

Recent Advances in Tomato Breeding and Production

The tomato is susceptible to pest attacks that can lead to damages throughout the crop cycle. Pest control is carried out, mainly, by insecticide and chemical acaricide spraying. However, the use of chemical pest control can cause severe damage to the environment, biological imbalances and deleterious effects on farmers and consumer health, as well as increased production costs. An interesting alternative to minimizing the problems arising from the agrochemical application and maintaining pest populations below the economic damage level is the development of tomato plants displaying resistance to insect and arachnid pests. In this context, the main purpose of this chapter is to provide a review of the techniques applied in this regard, major progresses to date and future prospects for tomato pest-resistance breeding. This chapter is divided into five sections: (1) wild pestresistant tomato species, (2) allelochemicals that confer pest resistance, (3) techniques used for the introgression of pest resistance genes (4) overview, challenges and prospects for pest-resistant tomato breeding and (5) final considerations.

“…Environmental safety of insecticides is the first and foremost criterion for TLM control programs (Tropea Garzia et al, 2012). In most countries where T. absoluta occurs, the main control strategy includes frequent sprays with chemical insecticides because without control, T. absoluta causes about 100% yield losses and dramatically decreases the fruit quality in both field and greenhouse tomato crops (Gilardón et al, 2001;Tropea Garzia et al, 2012). Nevertheless, because of the development of resistance, chemical control has demonstrated limited efficacy even after the use of different types of pesticides and increasing the application frequencies (Lietti et al, 2005;Siqueira et al, 2000).…”

“…Nevertheless, because of the development of resistance, chemical control has demonstrated limited efficacy even after the use of different types of pesticides and increasing the application frequencies (Lietti et al, 2005;Siqueira et al, 2000). This has led to the use of nonchemical control strategies, such as exploitation of the biocontrol provided by indigenous natural enemies (Zappalà et al, 2013) or the use of plant resistance with less environmental impact (Gilardón et al, 2001). The utilization of eco-friendly and easily biodegradable plant products with natural insecticidal activity has increased in recent years.…”

Tuta absoluta is one of the key pests of Solanaceae family in the world. This insect is an oligophagous pest and its larva causes damage on the host plants by feeding on leaf, stem and fruit of them. In the current study, chemical composition and insecticidal activities of the essential oil from cardamom, Elettaria cardamomum on egg, the 2nd larval instars and adults of T. absoluta were evaluated. Results indicated that oil is toxic to the T. absoluta. The major components in the oil were as follow: terpinenyl acetate (36.61%), 1,8-cineole (30.42%), linalyl acetate (5.79%) and sabinene (4.85%). LC50 values for eggs, larvae and adults were 351.19, 7.88, 1.55 and 1.88 ml L À1 air, respectively. The tomato leaf miner (TLM), T. absoluta (Meyrick) (Lepidoptera: Gelechiidae), is a important pest on tomato, potato and other Solanaceous with a huge economic importance. TLM can be regarded as a serious threat to tomato production in Iran. TLM larvae cause about 100% losses by attacking tomato leaves, flowers, stems and especially fruits. The discovery of active compounds that are less persistent will be beneficial to both the environment and agricultural product consumers. Management of the pest can be problematic, especially when the infestation pressure is high. The utilization of natural compounds such as plant essential oils is considered as a alternatives to chemical pesticides because of their lower toxicity on the non-target and low persistence in the environment. In the present study, the chemical composition and insecticidal activities of the essential oil from cardamom, E. cardamomum (Maton) (Zingiberales: Zingiberaceae) on egg, the 2nd larval instars and adults of T. absoluta were evaluated. The essential oil was obtained by hydrodistillation method, using a modified clevenger-type apparatus. Experiments were performed at 27 ± 2 C, 65 ± 5% RH and 16 L:8D h photoperiods. Results showed that the essential oil of E. cardamomum is toxic to T. absoluta. The major components in the oil were a-terpinyl acetate (36.61%), 1,8-cineole (30.42%), linalyl acetate (5.79%) and sabinene (4.85%). Probit analysis showed that the LC 50 values for eggs, 2nd larval instar (inside leaf, outside leaf) and adults were 351.19, 7.88, 1.55 and 1.88 ml L À1 air, respectively. The overall results showed that cardamom essential oil has high potential in controlling TLM, especially in protected areas.
