During the months of June and July, 1970, severe defoliations of
young teak plantations were observed in several localities of Chittagong,
Chittagong Hill Tracts North and Cox’s Bazar Divisions ( see Table I ) •
Especially leaves in the upper part of the crowns were eaten causing the
teak look rather naked as during winter time. The leaves were eaten up
except the major veins, as showns in Figure 1 •
