“…In spite of the many attempts to valorize natural enemies and apply efficient and ecological friendly biological control (Desneux et al 2010;Zappala et al 2012;Luna et al 2015;Shaltiel et al 2015), chemical insecticides are the main control strategy used against T. absoluta (Picanc ßo et al 1995). These are applied as direct sprays on the canopy, as soil applications (Larra ın et al 2014) or as impregnated nets or screens (Biondi et al 2015).…”

The tomato leaf miner, Tuta absoluta (Lepidoptera: Gelechiidae), is a major invasive pest that has spread throughout many countries in the Mediterranean basin and parts of Asia over the last decade. The control of T. absoluta has relied heavily on the use of chemical insecticides, a strategy that has led to the evolution of resistance. In this study, biological and molecular methods were used to determine the susceptibility of five strains of T. absoluta to the organophosphate chlorpyrifos and to investigate the molecular mechanisms underlying resistance to this class of insecticides. High levels of resistance to chlorpyrifos were observed in all five strains tested. Cloning and sequencing of the gene encoding the organophosphate target site, ace‐1, of T. absoluta revealed the presence of an alanine to serine substitution at a position that has been previously linked with organophosphate resistance across a range of different insect and mite species. The presence of this mutation at high frequency in T. absoluta populations originating from various countries further supports the suggestion that the rapid expansion of this species is, in part, mediated by the resistance of this pest to chemical insecticides.

“…Soon after its establishment in the Mediterranean countries T. absoluta has become a major threat for the tomato crops (Desneux et al 2010). Control of T. absoluta under IPM strategies should include an array of measures such as sanitation, the use of insect exclusion nets on the greenhouse openings, monitoring by sexual pheromone traps (Benvenga et al 2007), mass trapping (Witzgall et al 2010), biological control (Desneux et al 2010, Trottin-Caudal et al 2012, Terzidis et al 2014, Luna et al 2015, Cabello et al 2015 and application of insecticides (Roditakis et al 2012, Biondi et al 2013. The wide application of insecticides may cause adverse health effects to consumers and the environment but also may lead to inconsistent results and failures in control as resistance development in T. absoluta has been reported for abamectin, certain pyrethroids and chitin synthesis inhibitors (Siqueira et al 2001, Lietti et al 2005, Silva et al 2011, Campos et al 2015.…”

“…Biological control is a valuable strategy against T. absoluta populations since several natural enemies of this pest have been reported (Desneux et al 2010, Garcia del Pino et al 2013, Gabarra et al 2014, Luna et al 2015. The native of the Mediterranean region polyphagous predator Macrolophus pygmaeus (Rambur) and the cosmopolitan predator Nesidiocoris tenuis (Reuter) (Heteroptera: Miridae) may highly contribute to the control of whiteflies and other greenhouse pests on tomatoes (Albajes and Alomar 1999, Perdikis et al 2011, Itou et al 2012.…”

The invasive pest of the tomato crops, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), soon after its establishment became a major problem of outdoor and greenhouse tomato crops across the Mediterranean countries. The pre-plant release of the predator Nesidiocoris tenuis (Reuter) (Heteroptera: Miridae) has been found to substantially contribute to its establishment on the crop and efficient control of T. absoluta in greenhouses. The aim of the current study was to assess whether the pre-plant release of N. tenuis could contribute to its earlier establishment. It was concluded that the release of N. tenuis in the nursery contributed substantially in the earlier increase of its numbers in the field in comparison to the control plots. The native populations of M. pygmaeus appeared on the tomato plants before the native populations of N. tenuis. Thus, the conservation of both predators should be taken into consideration in the integrated management strategies against T. absoluta. Therefore, the application of this method in open field tomato crop enhances the earlier establishment of N. tenuis and should be further evaluated in the control of T. absoluta.

“…In its region of origin, T. absoluta is associated with many indigenous parasitoids on tomato plants (Vargas, ; Colomo et al , ; Luna et al , ). Among them, the native larval endoparasitoid Pseudapanteles dignus (Muesebeck) (Hymenoptera, Braconidae) is a promising candidate for use in augmentative releases for T. absoluta control.…”

1 The South American tomato moth Tuta absoluta is a major pest targeted for biological control by entomophagous insects. Trophic interactions among parasitoids of T. absoluta and other gelechiids feeding on crop and spontaneous wild solanaceous were investigated in north-eastern Buenos Aires (Argentina), with the aim of assisting in the design of conservation biological control strategies. 2 A quantitative parasitoid trophic web was constructed that included five gelechiid leafminers, five solanaceous species and a complex of 18 parasitoid species. 3 The relative abundance of T. absoluta was highest in the Solanum melongena crop, followed by the wild plants Nicotiana glauca, Solanum americanum, Solanum sisymbriifolium and Salpichroa origanifolia. Greater parasitoid species richness associated with T. absoluta was found in the wild plants N. glauca and S. americanum. 4 Pseudapanteles dignus was the main parasitoid of T. absoluta and co-occurred with this pest in four plant species. 5 Parasitism of T. absoluta by P. dignus was observed throughout the year in S. melongena, reaching values up to 33%, whereas it was sporadic and exhibited lower parasitism rates in the noncrop S. sisymbriifolium, N. glauca and S. americanum. 6 The presence of some wild solanaceous plants should be promoted to maintain the T. absoluta-P. dignus interaction in horticultural farms.
