Abstract

Oak forests are dwindling in the Western Himalayan region. Curculio sikkimensis which is a pest of Oak acorns may be considered as one of the major causes which has resulted in decrease in natural regeneration. All the three instars of larvae were observed to feed on the endosperm tissue of the acorns. The third instar larvae usually ate away almost the whole endosperm and turned it into frass. The extent of damage was found to be higher in the pure forests (81.6%) than as compared to the scrub forests (48%). Infestation was found to be higher in case of the acorns collected from the tree crown than as compared to the acorns collected from the forest floor.
