Major insect pests on the sawtooth oak Quercus acutissima Carruth grown in Manipur included Phalea raya Moore, Apoderus notatus Fabricius, Hyblaea puera Cramer, Cleoporus lefevrei Duvivier and Batocera lineolata Chevrolat. The population dynamics and incidence of A. notatus and P. raya are positively correlated with maximum and minimum temperatures. H. puera showed positive correlation with maximum temperature while B. lineolata was negatively correlated. Relative humidity had no significant effect on P. raya, A. notatus and C. lefevrei, but was insignificantly but negatively correlated with H. puera, A. densatus and B. lineolata. Population dynamics showed that P. raya was independent while the population build up of A.notatus was dependant of H. puera and C. lefevrei.
