“…The COI sequence and phylogenetic tree matched the T. absoluta (100% identity) sequences KJ657881, KJ657680, KC852871, KT452897, KP793742, KC852872 (see Fig. 9), as well as KX443111 and KX443108 [42], KP793741 (first report from India, Asokan et al 2015, unpublished data), KP814057 [43] and JQ749676 [44]. Phylogenetic analysis showed genetic distances between 0.00 and 0.59 between the Botswana T. absoluta sample and other samples deposited in the GeneBank, and between 12.67 and 12.84 between T. absoluta samples and the outgroup Ephysteris promptella.…”

Background:The tomato leaf miner Tuta absoluta (Lepidoptera: Gelechiidae) is an invasive insect pest of tomato and other solanaceous plants which is rapidly expanding its geographic range. It has a highly damaging effect on tomatoes and potential of threatening food production and consequently national food security. Here, we report on the first detection of T. absoluta in Botswana, its consequences on agriculture and food security, and recommend on management strategies. The pest was observed feeding on Solanum lycopersicum L. plants at Genesis farm, Matshelagabedi village in northern Botswana. Following detection, we incubated infected tomato fruits until adult eclosion. External morphology was conducted and confirmed at Botswana International University of Science and Technology (Botswana). Molecular identification and morphological male genitalia were confirmed at Stellenbosch University (South Africa). In addition, we set up some sex-specific pheromone (Tuta optima PH-937-OPTI) at the core detection site and surrounding areas.Results: Morphological genitalia features of pheromone-baited trap catches confirmed the insect pest was indeed T. absoluta. Molecular analysis also confirmed the morphological identification and thus confirming this first report of T. absoluta in Botswana. Conclusion:This first record of T. absoluta in Botswana is worth reporting to promote coordinated efforts amongst stakeholders, research specialists and extension officers in Botswana and across the southern African region in monitoring and managing the pest.

“…Although it has preference for tomato as host (Sridhar, Nitin, Onkara, & Nagaraja, 2015), other solanaceous crops are also important food source for the pest (Notz, 1992), for instance, Pereyra and Sánchez (2006) stated that T. absoluta is confined to tomato but could be a potential pest for potato crops in Argentina, as it is already a devastating pest of potato crop in Peru (Cisneros & Mujica, 1998). In India, it occurs on other solanaceous crops besides tomato and potato (Shashank, Chandrashekar, Meshram, & Sreedevi, 2015;Sridhar et al, 2014).…”

The influence of host plant on population dynamics of an invasive pest, Tuta absoluta was studied on three economically important solanaceous crops. Experiments were conducted in laboratory (29 ± 0.5°C, 75 ± 5% RH and a photoperiod of 14:10 hr [L:D]) using tomato (Solanum lycopersicum L.), potato (Solanum tuberosum L.) and eggplant (Solanum melongena L.). Results indicated that intrinsic rate of increase (r), finite rate of increase (λ) and net reproductive rate (R0) were higher, and mean generation time (T) was the shortest on tomato. Results suggested that T. absoluta developed on all the three plants, and tomato plant was most preferred one. Results suggested that T. absoluta has a potential to become a serious pest on potato and even on eggplant under favourable conditions. We used the life tables of 0.025th and 0.975th percentiles of bootstraps to project the uncertainty of population growth, a new concept.

“…Tuta absoluta attained global prominence as an invasive pest in 2006 when it was introduced into Spain (Tropea Garzia et al 2012). It has since invaded other countries in Europe, the Mediterranean, northern Africa (Desneux et al 2011;Mohamed et al 2012), and South Asia (Kalleshwaraswamy et al 2015;Shashank et al 2015;Bajracharya et al 2016;Hossain et al 2016). Tuta absoluta also crossed the Sahara Desert and is now seen as a serious threat to tomato production in sub-saharan Africa (Brévault et al 2014), where preliminary reports suggest it has already reached South Africa, invading Tanzania and several other countries on the way (Chidege et al 2016;Campos et al 2017).…”
