“…Alien species are responsible for reducing yields, increasing the use of pesticides and subsequently increasing production costs (Ragsdale et al 2011;Wan and Yang 2016). The South American tomato pinworm Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) has been considered a worldwide invasive pest, which invaded Europe in 2006 and spread throughout the Afro-Eurasian supercontinent (Campos et al 2017;Sankarganesh et al 2017;Sylla et al 2017;Biondi et al 2018;Han et al 2018;Mansour et al 2018). This South American native moth has a life cycle of about 26-75 days, according to the upper and lower developmental thresholds (34.6 and 14 °C), and generational overlap has been observed in the field (Guedes and Picanço 2012;Martins et al 2016).…”

The development of new strategies to control pest insects is required, in combination with conventional pesticides or replacing them. Essential oils produced from botanical extracts used in management programs should be effective against pests and selective to natural enemies. Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is one of the most destructive pests of solanaceous crops in the world, and a possible management strategy consists of releases of the predator Nesidiocoris tenuis (Hemiptera: Miridae), along with botanical applications. The objective of this study was to evaluate the effects of Prev-am ® oil on T. absoluta offspring, either with or without the predator N. tenuis, as well as the oil's effects on N. tenuis predatory behavior and longevity. The oil's effects were compared with distilled water (control) and a synthetic pesticide (lambdacyhalothrin). The response of populations to lambda-cyhalothrin was similar to that with Prev-am ® , compared to the control, showing that N. tenuis had higher capacity to reduce T. absoluta populations. The survival analysis of predators exposed to Prev-am ® indicates that none of the concentrations differed significantly from the control. In addition, the canonical variate analysis indicated significant overall differences in the predator behavior submitted to different treatments, suggesting that synthetic pesticide treatment affected predator behavior when compared to control and Prev-am ® . Reduction in predatory voracity of N. tenuis adults exposed to leaves treated with pesticide and biopesticide was significant compared to the control treatment. The results obtained could improve IPM programs against T. absoluta through the Prev-am ® applications and N. tenuis releases.Keywords Natural product · Predatory mirid · South American tomato pinworm · Ecotoxicology · Biological control Key message• New strategies based on the use of natural enemies and biopesticides to control Tuta absoluta are desirable for integrated pest management (IPM). • The combination of Nesidiocoris tenuis with Prev-am ® (at half of the recommended concentration) showed enhanced efficacy against T. absoluta. • Presence of N. tenuis significantly reduced T. absoluta population growth. • Lambda-cyhalothrin and Prev-am ® could disturb behavioral response of N. tenuis.

“…Three recent reviews on this pest for the Afro-Eurasian region , Mediterranean Basin (Giorgini et al, 2019) and Africa (Mansour et al, 2018) have provided extensive information on the biology and ecology of Tuta absoluta and its worldwide spread. Tuta absoluta's primary host is tomato, though it can feed and develop on other members of the Solanaceae.…”

“…Since the first detection in North Africa -Tunisia and Morocco -in 2008, Tuta absoluta has spread at an average speed of 800 km per year, both eastward and southward , Giorgini et al, 2019 to other sub-Saharan countries, where it has become a major pest. Currently, Tuta absoluta is reported in 41 of the 54 African countries (Mansour et al, 2018). It was reported in West Africa -Niger and Nigeria in 2010, and Senegal in 2011; East Africa -Kenya in 2014, Tanzania in 2014 and Uganda in 2015; and southern Africa -Botswana, Zambia and South Africa in 2016 (Mohamed et al, 2012;Pfeiffer et al, 2013;Brévault et al, 2014;Retta and Berhe, 2015;Tonnang et al, 2015;Chidege et al, 2016Chidege et al, , 2017Tumuhaise et al, 2016;Mutamiswa et al, 2017;Visser et al, 2017;Zekeya et al, 2017, Mansour et al, 2018.…”

“…One of the most serious pests of tomatoes is the South American tomato pinworm Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), which has invaded various regions around the globe including Europe (Desneux et al, ; Giorgini, Guerrieri, Cascone, & Gontijo, ), Asia (Campos, Biondi, Adiga, Guedes, & Desneux, ; Han et al, ) and Africa (Mansour et al, ). Tuta absoluta is a key pest of both field and greenhouse tomatoes (Giorgini et al, ) and can cause losses of as much as 100% if control measures are not implemented in time (Lopez, ; Picanço, Leite, Guedes, & Silva, ; Tropea, Siscaro, Biondi, & Zappalà, ).…”

Augmentative biological control (ABC) is crucial for the integrated pest management (IPM) of greenhouse pests. The proper calculation of natural enemy:pest release ratio (NEPRR) stands out among the various challenges of ABC. Often, most NEPRR calculations only take into account the predation/parasitism efficiency of natural enemies, while disregarding pest population growth capacity, population structure and/or economic thresholds. In a model system consisting of Trichogramma pretiosum Riley parasitizing eggs of Tuta absoluta (Meyrick) on greenhouse tomatoes, we investigated whether a stage‐structured Lefkovitch matrix could be used to determine suitable NEPRRs. The results suggested that these matrix models can potentially provide more precise and realistic predictions of NEPRRs since they account for differential pest population growth over time as a response to natural enemy action. The matrix models could also allow us to choose an adaptable NEPRR based on parameters such as the period the grower wishes to keep the pest population below economic threshold.
