Abstract
Ten different national provenances and four different seedling (RT, PB, PT & RS) raised plantations of Gmelina arborea were screened against bark eating caterpillar Indarbela quadrinotata. Ghotil, Maharashtra provenance and root shoot seedling raised plantations were found to be more resistant showing 6.66% and 5% infested plants with least number of holes and less penetration. Other bio-physical test parameters like diameter of the tree trunk, height or age of the plants and the moisture content of the bark play an important role in imparting resistance of G. arborea to I. quadrinotata.
