“…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.…”

“…Switzerland, the UK, Germany and the Netherlands), though this has been restricted to protected tomato cultivation (Potting et al, 2013). Some years later, Tuta absoluta is now established outdoors in all countries around the Mediterranean Sea and in the Middle East (Desneux et al, 2010;Biondi et al, 2018, Giorgini et al, 2019.…”

“…Figure 5 below shows the individual country status as regards Tuta absoluta presence (EPPO, 2018). 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).…”

“…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, ). Among the most promising biological control agents, the egg parasitoids Trichogrammatidae have received substantial research attention as a potential natural enemy to be deployed in the ABC of T. absoluta (Cabello et al, ; Cagnotti et al, ; Cherif, Mansour, Attia‐Barhoumi, Zappalà, & Grissa‐Lebdi, ; Gontijo et al, ; Parra & Zucchi, ).…”

Using life stage‐structured matrix models to determine natural enemy:pest release ratios for augmentative biological control

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.

BACKGROUND: Forecasting the spread of emerging pests is widely requested by pest management agencies in order to prioritise and target efforts. Two widely used approaches are statistical Species Distribution Models (SDMs) and CLIMEX, which uses ecophysiological parameters. Each have strengths and weaknesses. SDMs can incorporate almost any environmental condition and their accuracy can be formally evaluated to inform managers. However, accuracy is affected by data availability and can be limited for emerging pests, and SDMs usually predict year-round distributions, not seasonal outbreaks. CLIMEX can formally incorporate expert ecophysiological knowledge and predicts seasonal outbreaks. However, the methods for formal evaluation are limited and rarely applied. We argue that both approaches can be informative and complementary, but we need tools to integrate and evaluate their accuracy. Here we develop such an approach, and test it by forecasting the potential global range of the tomato pest Tuta absoluta. RESULTS:The accuracy of previously developed CLIMEX and new statistical SDMs were comparable on average, but the best statistical SDM techniques and environmental data substantially outperformed CLIMEX. The ensembled approach changes expectations of T. absoluta's spread. The pest's environmental tolerances and potential range in Africa, the Arabian Peninsula, Central Asia and Australia will be larger than previous estimates.CONCLUSION: We recommend that CLIMEX be considered one of a suite of SDM techniques and thus evaluated formally. CLI-MEX and statistical SDMs should be compared and ensembled if possible. We provide code that can be used to do so when employing the biomod suite of SDM techniques.
