A study was undertaken to analyse the fruit feeding preference of Helicoverpa armigera (Hubner) larvae towards tomato accessions as influenced by growth hormones. The influence of growth hormones on the fruit feeding preference of fruit worm H. armigera 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, Annamalai University, Tamil Nadu. The fruit feeding was the minimum in the plants that received foliar application of Salicylic Acid (SA), irrespective of the accessions followed by NAA applied plants.
