Abstract

Background: Pest invasion has been a disruptive phenomenon in nature, the consequence being ecological and economical negative effect in natural ecosystem of the area. In agriculture, introduced insect pest has a devastating effect on food production. Such a phenomenon occurred in Ngabobo village, Ngarenanyuki, King'ori, in the Arumeru District of Tanzania, a key tomato production area, when boring Lepidoptera larvae were found on aerial parts of tomato (Solanum lycopersicum L.) plants between 2014 and 2015. Larvae created blotched leaf galleries and superficial mines on fruits. Results: The pest was identified as Tuta absoluta (Meyrick 1917) (Lepidoptera: Gelechiidae) by the leaf and fruit damage symptoms inflicted, the adult morphology as well as using specific pheromone traps (TUA optima lure) against adult male Tuta absoluta. Conclusion: This is the first record of tomato leaf miner Tuta absoluta (Meyrick 1917) (Lepidoptera: Gelechiidae) in Tanzania worth to report. This information will help to design sustainable management tactics against this notorious pest of tomato in the country and the neighbouring countries of sub-Saharan Africa.
