Tuta absoluta (Tomato leaf miner): New host records, controls, and distribution


Name: Tuta absoluta Meyrick

Taxonomic Position:

Animalia : Arthopoda : Insecta : Lepidoptera : Gelechiidae

Common Names:

Tomato leaf miner


Tuta absoluta has been highlighted in previous NAPPO-PAS Pest Alerts (, It is a significant pest of Solanum lycopersicum (tomato) and other economically important solanaceous plants, such as Solanum tuberosum (potato) and Capsicum annuum (pepper), and has also been found on Phaseolus vulgaris (bean).

Issues of Concern:

A recent publication reports that, during a 2009 to 2011 survey, Tuta absoluta was found infesting Beta vulgaris (beet), Chenopodium bonus-henricus (good King Henry), C. rubrum (red goosefoot), and Spinacia oleracea (spinach) plants in Algeria (Drouai et al., 2016). This is the first report of these plant species as hosts of T. absoluta.

Control of Tuta absoluta is mainly through chemical means, but the larvae feed internally and quickly can develop resistance. During a 2010 to 2014 study in Italy and Greece, Tuta absoluta exhibited resistance to the diamide insecticides chlorantraniliprole and flubendiamide, which is the first report of T. absoluta resistance to this type of insecticide. High resistance levels (>1,000-fold) were detected in Italy, and low but increasing resistance levels (>10-fold) were detected in Greece (Roditakis et al., 2015). Some biological controls are available, such as the mirid bugs Nesidiocoris tenuis and Macrolophus pygmaeus (De Backer et al., 2014), and another publication reported that the assassin bug Zelus obscuridorsis (Hemiptera: Reduviidae) was observed on tomato plants infested with T. absoluta in household gardens in Argentina during 2012 surveys. Laboratory tests indicated that Z. obscuridorsis feeds on mobile larvae and adults of T. absoluta, but not on larvae within leaf mines, eggs, or pupae, which is the first report of a Zelus species feeding on T. absoluta (Speranza et al., 2015).


Tuta absoluta is native to South America and has been widely reported from parts of Central America, Europe, Africa, and the Middle East (CABI, 2016). Most recently, T. absoluta has been collected from pheromone traps in Zambia (IPPC, 2016a), South Africa (IPPC, 2016b) and Mozambique (IPPC, 2017), and there has been first reports from Nigeria (Aishat, 2016), Uganda (Tumuhaise et al., 2016), India (ICAR, 2015), Nepal (Bajracharya et al., 2016), Bangladesh (Hossain et al., 2016), and Botswana (Tebele, 2017). It is not known to occur in the United States, Canada, or Mexico.
