“…Similar threats to food security and estimates of high economic losses occur in developing Asian countries (Biondi et al 2018;Bahadur and Bikram 2019;Biondi and Desneux 2019;Han et al 2019). The majority of farmers in Africa and Asia are smallholders (Hruska 2019), most of whom before recent major biological invasions such as T. absoluta and Spodoptera frugiperda, used no pesticides (Rwomushana et al 2019;Hruska 2019).…”

Biological invasion risk assessment of Tuta absoluta: mechanistic versus correlative methods

The capacity to assess invasion risk from potential crop pests before invasion of new regions globally would be invaluable, but this requires the ability to predict accurately their potential geographic range and relative abundance in novel areas. This may be unachievable using de facto standard correlative methods as shown for the South American tomato pinworm Tuta absoluta, a serious insect pest of tomato native to South America. Its global invasive potential was not identified until after rapid invasion of Europe, followed by Africa and parts of Asia where it has become a major food security problem on solanaceous crops. Early prospective assessment of its potential range is possible using physiologically based demographic modeling that would have identified knowledge gaps in T. absoluta biology at low temperatures. Physiologically based demographic models (PBDMs) realistically capture the weather-driven biology in a mechanistic way allowing evaluation of invasive risk in novel areas and climes including climate change. PBDMs explain the biological bases for the geographic distribution, are generally applicable to species of any taxa, are not limited to terrestrial ecosystems, and hence can be extended to support ecological risk modeling in aquatic ecosystems. PBDMs address a lack of unified general methods for assessing and managing invasive species that has limited invasion biology from becoming a more predictive science.

“…After hatching, young larvae penetrate tomato fruits (Fig. 1c) [46] and feeding damage is caused when the larvae enter into the leaf and feed on the mesophyll tissue of leaves, as a result, developed irregular mines on the leaf surface and reduce the photosynthetic capacity of the plant [14,49].…”

Worldwide, tomato leaf miner Tuta absoluta (Lepidoptera: Gelechiidae) is one of the most devastating invasive pests of tomato crops. It is one of the most important biotic constraints for tomato production which may lead to the production loss up to 100% if it cannot be controlled. T. absoluta comprises four developmental stages: egg, larvae, pupa, and adult with a rapid growth rate. Among these larvae is the most devastating stage which affects the fruit, leaves, and stem. Recently, T. absoluta is turned into a key pest of tomato in Bangladesh. This pest was first detected by IPM lab, Horticulture Research Centre, Bangladesh Agricultural Research Institute, Gazipur, Bangladesh from a commercial tomato grower in the village of Chaklarhat (26019’N, 88043’E) under the Tunirhat union of Panchagarh Sadar Upazila, Panchagarh district of Bangladesh in May 2016. Since its introduction in 2016, there was no sound action plan implemented. Therefore, this paper focused on relevant scientific knowledge regarding its biology, potential damage and different control measures which will open the windows for future researches for efficient and sustainable management strategies against T. absoluta in Bangladesh.

“…In Egypt, it was reported that summer plantation that is harvested from the end of August to early September had the highest levels of infestation of T. absoluta (Saad et al 2014) and the yield losses were reported to range from 11% to 100% (Moussa et al 2013;. Therefore, the harmful effects of T. absoluta are extended to consumers as the increased price of the commodity and the potential presence of elevated levels of pesticide residues due to the application of large quantities during the management of this insect pest (Desneux et al 2007;Birhan 2018;Rwomushana et al 2019).…”

“…The T. absoluta insect attacks, not only the green foliage but also the flowers and fruits which lead to partial or complete yield destruction. To manage this devastating insect, farmers apply various strategies of detection, monitoring, pheromone traps, pesticides (chemical, microbial, botanicals, and organic), destruction of infected plants, and biocontrol agents (Rwomushana et al 2019). Due to the high infestation rates, growers apply large quantities of broad-spectrum insecticides, which might lead to widespread development of resistance, contamination of the fruits with pesticide residues, and human and environmental health hazards (Khalid 2011;Roditakis et al 2018;Silva et al 2011).…”

Tomato pinworm (leafminers), Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), is a difficult to control and an invasive insect pest that causes devastating damage to tomatoes. It was introduced in Egypt in 2009 from the North African Countries. Therefore, the availability of various management strategies is essential for tomato production in Egypt. The current study aimed to evaluate the insecticidal activity of different formulations of Emamectin Benzoate, Esfenvalerate, and Indoxacarb against T. absoluta under field conditions. All tested insecticides revealed elevated degrees of control of this insect in El-Behera Governorate. The management levels were > 74% and there were significant differences among the Emamectin Benzoate insecticidal formulations against T. absoluta compared to both Indoxacarb and Esfenvalerate after 10 days of spray in both seasons 2019 and 2020. The tested insecticides were found to be effective in controlling this insect for about 10 days after the spraying and could be recommended to be among the integrated management strategies.
