Review on Integrated Management of Tomato Leaf Miner, Tuta Absoluta (Mayrick ) (Lepidoptera: Gelechiidae) on Tomato Under Field and Glass House Conditions

Abstract

Tomato (Lycopersicon esculentum Mill.) belongs to the family Solanaciace, is one of the most widely grown vegetable in the world as well as in Ethiopia. Tomato leaf miner, T. absoluta (Meyrick) (Lepidoptera: Gelechiidae) is a key pest of tomato and its control is very important to the production and profitability of this crop. Therefore, this review showed that the experiment was worked in glass house of Ambo University and under field conditions in Guder, Western Showa Zone of Oromia Regional state, Ethiopia. A factorial experiment was laid out in randomized complete block design with three replications to evaluate the effect of insecticides and botanicals (Azadirachta indica L.) on tomato leaf miner under glass house and on farmers cultivated field. The results of the study revealed that the newly introduced two insecticides gave promising mortality rate and not significantly different compared with the standard check and highly significantly different from the untreated check. The botanicals, A. indica fresh leaf and seed extracts with foliar application gave promising mortality rate when used as alternative control measures for tomato leaf miner, while the two botanicals part were found lesser effective as compared with other treatments, but significantly different from untreated check. From this study, it could be concluded that the two insecticides Cutter 112 E.C TM and Trigger 5% E.C TM were effective recommended as alternative insecticides. The botanical (A. indica) both fresh leaf extract and seed extract (bio-pesticide), which are easily available locally, are better option and eco-friendly for controlling tomato leaf miner in the study areas.
