Abstract: The influence of organic and inorganic sources of nutrients and the external elicitor, salicylic acid on the entrapment and impedance of fruit worm, Helicoverpa armigera (Hubner) in an already identified insect tolerant, tomato accession Varushanadu Local in comparison with a susceptible check, I 979 was studied under glasshouse conditions at Department of Entomology, Faculty of Agriculture, Annamalai University. Among the organic and inorganic sources of nutrients applied plants, salicylic acid treated plants of Varushanadu Local entrapped the neonates caused the maximum mortality.
