Effects of defoliation from an outbreak of the teak skeletoniser, Paliga damastesalis walker (Lepidoptera: Crambidae), on the growth of teak, Tectona grandis L.

The effects of defoliation by the teak skeletoniser Paliga damastesalis Walker (Lepidoptera: Crambidae) on a six-month old stand of teak Tectona grandis L. was evaluated on the subsequent year-long growth in the field. Defoliation did not exceed 10%. It had a transient negative effect on post-defoli...

As for the remaining period of the dry season after July, new leaf production remained at a constant low level, while increments for both the height and collar diameter were found to decrease.
