IntroductionTomato (Lycopersicon esculentum Miller) is one of the most widely grown vegetables in the world 1 . Tomato leaf miner, Tuta absoluta (Lepidoptera: Gelechiidae) is an aggressive pest that causes serious damage in tomato production, resulting in up to 100% yield losses during serious outbreaks (Flores et al, 2003;Saidov et al, 2018). Among the lepidopteran pests of tomato crop, T. absoluta is considered as a highly invasive agricultural pest, which is native to Latin America and has spread through most of Europe, Mediterranean regions, and many other regions worldwide (Hassan and Alzaidi, 2009;Mansour et al, 2018).

Tomato leaf miner is an aggressive and invasive pest that causes serious damage in tomato production resulting in up to 100% yield losses during serious outbreaks. The management of tomato leaf miner with synthetic pesticides is difficult due to its leaf mining habit, short life span, high reproductive rates and inseciticide resistance problem. In this study, sequences of the mitochondrial cytochrome oxidase I (mtCOI) gene of Tuta absoluta 2 specimens were analyzed and compared with the available COI sequence data members from GenBank. All specimens of tomato leaf miner were clustered together in a single group with a high support value, suggesting the presence of a homogeneity in the T. absoluta specimens. Furthermore, 164 samples were analyzed in order to detect the prevalence of Arsenophonus, Cardinium, Hamiltonella, Pantoea, Spiroplasma and Wolbachia infection in T. absoluta populations. PCR analysis revealed 100% prevalence Wolbachia and Pantoea however, no other symbiotic bacterial infections were observed in T. absoluta populations. Finally, Wolbachia wsp, Pantoea 16S ribosomal RNA genes and mtDNA COI haplotypes were analyzed in order to estimate the mitochondrial effects of these endosymbionts on the population structure of tomato leaf miner. The findings of high genetic homogeneity among T. absoluta populations with high prevalence of Wolbachia and Pantoea infections seems to imply that both bacterial infections has less impact on the mtDNA variations.

“…Subsequently, Bangladesh, Nepal, and several countries in Central Asia had also reported the presence of this pest. In contrast, detections of this insect have not been announced in North America and some parts of Asia such as Cambodia, Japan, Laos, Indonesia and Thailand [5][6][7][8][9]. To the best of our knowledge, there are no official reports of T. absoluta presence in most Southeast Asian countries [9,10].…”

The South American tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), one of the most important invasive insect pests affecting tomato production worldwide, was for the first time detected in Myanmar. Preliminary surveys on pest occurrence on tomato crops in Myanmar suggested the presence of T. absoluta in Southern Shan State, but there was no official survey conducted until the end of 2019. Therefore, this study aimed to confirm the presence of T. absoluta in Myanmar. The presence of T. absoluta was specifically observed in the Southern Shan State, which is the largest tomato production area in Myanmar, where tomato is grown under two cultivation methods, floating and land cultivation. The highest T. absoluta infestation was recordedat Kalaw with (82%), followed by Inle Lake (i.e., floating cultivation) (20%) and Pin Ta Ya (10%). The amount of T. absoluta larvae was significantly higher in the lower third of the plants, followed by the middle section and upper section, respectively, in three fields surveyed. Potential and severe economic damage may be expected if management practices are not in place to reduce the presence of this invasive pest. It is of immediate importance that plant protection and quarantine offices of ASEAN member states coordinate their response to T. absoluta and build their capacity to monitor the pest and develop a strategy for when it arrives. In addition, a suitable management strategy is needed to reduce the occurrence of this invasive pest.

“…T. absoluta can cause high production losses of tomato (i.e. up to 100%) in open field and greenhouse cultivation if left uncontrolled [14][15][16][17]. Thus, this review paper aims at establishing the problems package and management strategies towards an available, eco-friendly, cost-effective, and sustainable management of the pest.…”

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.
