“…To the best of our knowledge, no study on L. camara EO bioactivity against T. absoluta, together with their toxicity differences from oils sourced from the same plant but differing climatic zones, and their repellency activity has been recorded. However, previously, several researchers have tested the EOs from other plants against T. absoluta larvae for toxicity (Abdel-Baky and Al-Soqeer, 2017;Allam Tarik, 2015;Chegini et al, 2018;Javier et al, 2017;Khaoula, 2013;Moreno et al, 2012;Soares et al, 2019;Yarou et al, 2018) and their repellence activity (Allam Tarik, 2015). The EOs showed considerable toxicity and repellency activity on the T. absoluta larvae, comparable to the other plants EOs.…”

In recent years, essential oils (EOs) as alternatives to synthetic pesticides in managing pests have been assessed. The use of bioinsecticide in pest management is encouraged in agroecology for a sustainable agricultural system. Essential oils of Lantana camara L. leaves from different climatic zones of Kenya were extracted by steam distillation and analyzed through GC-MS to identify the compounds. The contact toxicity and repellent activity of EOs against the invasive tomato pest, Tuta absoluta, were tested. The toxicological assays were performed following the leaf-dip bioassay protocol, while the repellency activity was performed using the repellent response method for phytophagous pests and the data analyzed using the ANOVA test. It was found that L. camara EO has a good insecticidal activity with higher mortality (89%) on the 2 nd instar larvae with a higher dosage (0.01 µl/µl). The repellence test also showed a higher average repellence (93.44%) effect with a higher dosage (0.01 µl/µl) of the EOs. According to these results, the EO of L. camara may well be a sustainable, eco-friendly alternative for synthetic insecticide in the T. absoluta management program.

“…While spreading from one location to another, T. absoluta causes crops damage, with losses which can reach up to 100% in tomato production [10,23]. However, the complex physiology and ecology of T. absoluta may be in part responsible for the lack of successful management strategies [10], in spite of multiple activities and efforts undertaken both in laboratory and in the field during the last decade to control this invasive pest [24][25][26][27][28][29][30][31][32][33][34][35]. Tuta absoluta has a high reproduction rate, with about 12 generations per year in optimal conditions, which range between 21 to 30 • C, and higher than 50% relative humidity.…”

Exploring the Mechanisms of the Spatiotemporal Invasion of Tuta absoluta in Asia

et al. 2020

International crop exchange always brings the risk of introducing pests to countries where they are not yet present. The invasive pest Tuta absoluta (Meyrick 1917), after taking just a decade (2008–2017) to invade the entire Africa continent, is now continuing its expansion in Asia. From its first detection in Turkey (2009), the pest has extended its range of invasion at a very high speed of progression to the southeast part of Asia. This study adopted the cellular automata modelling method used to successfully predict the spatiotemporal invasion of T. absoluta in Africa to find out if the invasive pest is propagating with a similar pattern of spread in Asia. Using land cover vegetation, temperature, relative humidity and the natural flight ability of Tuta absoluta, we simulated the spread pattern considering Turkey as the initial point in Asia. The model revealed that it would take about 20 years for the pest to reach the southeast part of Asia, unlike real life where it took just about 10 years (2009–2018). This can be explained by international crop trade, especially in tomatoes, and movement of people, suggesting that recommendations and advice from the previous invasion in Europe and Africa were not implemented or not seriously taken into account. Moreover, some countries like Taiwan and the Philippines with suitable environmental condition for the establishment of T. absoluta are not at risk of natural invasion by flight, but quarantine measure must be put in place to avoid invasion by crop transportation or people movement. The results can assist policy makers to better understand the different mechanisms of invasion of T. absoluta in Asia, and therefore adjust or adapt control measures that fit well with the dynamic of the invasive pest observed.
