- 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).
