“…Outside its native home, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) was detected for the first time in Spain in 2006 (Urbaneja et al 2008), and since then, it has invaded many countries including India (CABI 2018). At present, the pest has spread to almost all the tomato growing parts of India (Sridhar et al 2014;Ballal et al 2016 andSharma andGavkare 2017). The larvae cause damage by mining into the leaves, shoots, flowers, buds, and fruits (Sharma and Gavkare 2017).…”

Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), one of the most destructive pests of tomato, has recently invaded India. Before recommending any bio-control agent for its control, it is important to study the demographic parameters of the bio-agent on the pest. The present study evaluates the demographic parameters of indigenous trichogrammatids namely Trichogramma achaeae Nagaraja and Nagarkatti, T. pretiosum Riley, T. chilonis (Ishii), and T. pieridis Nagaraja and Prashanth against this pest, aiming to select the most effective egg parasitoid species. Significant differences were observed among the demographic parameters of different Trichogramma spp. Parasitization potential of a thelytokous strain of T. pretiosum was the highest, followed by T. achaeae, T. chilonis, and T. pieridis. Population growth parameters net reproductive rate, intrinsic rate of natural increase, finite rate of increase, and weekly multiplication rate were highest, and generation time and doubling period were shortest for T. pretiosum, followed by T. achaeae, T. chilonis, and T. pieridis. The study concluded that T. pretiosum could be considered a potential candidate for biological control of T. absoluta; however, field evaluation is required before final recommendation.

“…The temperature dataset was obtained from the WorldClim database (http://www.worldclim.org/current) (Hijmans et al, 2005); relative humidity data were downloaded on the Surface meteorology and Solar Energy (SSE) website (http://eosweb.larc.nasa.gov/sse/). However, T. absoluta occurrence data in Asia were collected from different scientific publications [16][17][18][19][20][21]. The temperature datasets were organized into monthly mean values using a grid of 30 arcseconds that correspond to about 1-km resolution.…”

“…Later, T. absoluta also invaded Africa through Morocco (2007Morocco ( /2008, Algeria (2008), Tunisia, Libya, (2009), Senegal (2011), Sudan (2011), Ethiopia (2013), Kenya (2013), and South Africa in 2017 [7][8][9][10][11][12][13], as well as Benin in 2018 [14]. Turkey was the first country in Asia to detect the presence of T. absoluta in 2009 [15], and from there it has spread and reached many countries in South and Central Asia including India (2015), the northwestern Himalayan region of India, Bangladesh (2016), Nepal (2016), Kyrgyzstan (2017), Tajikistan (2018) [16][17][18][19][20][21][22], and possibly in Myanmar (2018) in both greenhouse and open field conditions. However, despite the wide spread of T. absoluta in South Asia, the invasive pest has not yet been officially reported in many countries in Southeast or East Asia, including Laos, Thailand, Cambodia, Vietnam, Malaysia, Indonesia, Philippines, Taiwan, Koreas and Japan.…”

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.

“…The pest feeds on leaves, fruits, buds and apical shoots of tomato and is capable of causing 100 per cent crop damage in the absence of control measures (Urbaneja et al, 2012;Ballal et al, 2016). In India, the occurrence of this pest was recorded for the first time on tomato in Pune and Bengaluru during 2014 (Sridhar et al, 2014;Shashank et al, 2015), and since then it has spread to almost all parts of the country where tomato is grown (Sridhar et al, 2014;Kalleshwaraswamy et al, 2015;Kumari et al, 2015;Shashank et al, 2015;Ballal et al, 2016;Sharma and Gavkare 2017). In Himachal Pradesh, T. absoluta was detected for the first time in 2015 on tomato at Nauni, Solan (Sharma and Gavkare, 2017).…”

The present study deals with the impact of temperature on development, survival, reproduction and population growth of a recently invaded and the most destructive pest of tomato, Tuta absoluta (Meyrick) with the aim to understand its possible expansion in different agro-climatic zones. Though T. absoluta was able to develop between 15° and 35°C, temperature around 25°-30°C was more suitable. Survival and fecundity were highest at 25°C and lowest at 35°C. Developmental threshold for different developmental stages of the pest varied from 6.2 to 9.5°C, while the thermal constant required by the insect to complete the development from egg to adult emergence was 500 degree-days. Population growth parameters were also influenced significantly by the rearing temperature. Intrinsic rate of increase, net reproductive rate and finite rate of increase was higher at 25° and 30°C as compared to other temperature regimes. The study concludes that T. absoluta can be a serious pest of tomato in mid-hills of northwestern Himalayan region and the southern plains of India where temperatures varies between 15-35°C. Furthermore, the developmental threshold values indicate that the pest can develop and survive at temperatures as low as 6-9°C without entering the diapause as long as the food is available.
