Efficiency of some plant extracts against Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) under laboratory conditions

WOS: 000300345400011Efficiency of some plant extracts against Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) under laboratory conditions Tomato leaf miner [Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae)], originating from South America, is one of the most serious pest of tomato around the world. Tomato leaf miner feeds on all upper parts of the plant grown in both greenhouse and open field and damages up to 100% if it is not controlled. This pest is effected large areas around the world and it is a loss recorded in Turkey where it caused a major epidemic in 2009 resulting in a drastic increase in tomato prices in the Turkish market. Although many precautions and control methods are suggested against the Tomato leaf miner in integrated pest management programs, it is mainly controlled with conventional insecticide treatment. However, this species is developed resistance against many active compounds in South American where the pest is a problem for a long time. In this study, effects of plant extracts were tested on this destructive pest in laboratory and greenhouses conditions. Results showed that Anonin, Azadirachtin, and their mixtures were very effective in controlling the pest and it could be used against this pest within integrated pest management program in greenhouses and fields
