Heterobostrychus aequalis  Wat is very  important   wood  destroying   insect  other  than  termites.  In  this experiment pulai  wood  samples  (Alstonia  scholaris  R.Br)  taken  from  above  and  under  a girdle  of  cut  around  tree stem  were dried at temperature   40˚C,  60˚C,  90°C,   100°c,    120°c,    150°C, 200°c    and  air  temperature.   On  each  side  of  the  samples  of 1,5  cm  x  5  cm  x  7 cm.  Into   in  dimension   ten  holes  were  made  the  hole  larvaes of  1,5  month   old  were  placed.   The observations  were  made after  six  week  period. Wood dried at  temperature  40°C  had the lowest starch content  i.e 13,40  % for wood  samples  the girdle and 11,15  % for  wood  samples  under  the  girdle,  white   the  intensity   of  insect's  attack   can  be  rated  os moderate   (with  score  67,25 and  65,75).
