Foliage feeding preference of fruit worm larvae towards tomato accessions as influenced by phyto and growth hormones

Abstract

A study was undertaken to analyse the foliage feeding preference of Helicoverpa armigera (Hubner) larvae towards tomato accessions as influenced by phyto and growth hormones. The influence of phyto and growth hormones on the feeding preference of fruit worm H. armigera in an already identified insect tolerant, tomato accession Varushanadu Local in comparison with a susceptible check, 1979 was studied under glasshouse conditions at Department of Entomology, Annamalai University, Tamil Nadu, India. The foliage feeding was the minimum in the plants that received foliar application of SA, irrespective of the accessions followed by NAA applied plants.
