Efficacy of integrated pest management tools evaluated against Tuta absoluta (Meyrick) on tomato in India

摘要: South American tomato moth, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is an invasive pest on and other solanaceous crops. In general, 20 to 30 % yield loss caused by this sometimes it may result in 100% damage, if timely management interventions are not followed. Though the was reported India during 2014, presently has spread several growing states. present study various IPM tools have been evaluated against pest. As a long-term strategy of resistance breeding, genotype screening carried out for identification sources from wild cultivated genotypes showing resistance/tolerance T. . Among genotypes, Solanum pennellii (Accession, LA 1940) identified as resistant source both under choice no-choice bioassays being used breeding. Various entomopathogens ( Bacillus thuringiensis , Metarhizium anisopliae Beauveria bassiana M. rileyi ), egg parasitoids Trichogramma chilonis pretiosum Trichogrammatoidea bactrae light traps, pheromone synthetic insecticides, botanical origin insecticides were also their relative efficacy. among chemicals, spinetoram 12 SC@ 1.25ml/l found very effective Yellow traps component integrated Azadirachtin 5% EC at tested concentrations showed highest mean radial growth (24.67 mm) with relatively less inhibition (16.51%) indicating these combinations can be effectively utilised eco-friendly We natural incidence larvae, causing up 35 per cent mortality 2016-17.
