PATTERNS OF <i>Coptotermes</i> sp. TERMITE ATTACK ON <i>Shorea leprosula</i> Miq IN KHDTK SEBULU, EAST KALIMANTAN
Abstract
Red meranti (Shorea leprosula Miq) as a major commercial timber has been widely planted in Dipterocarp forests. Coptotermes sp. termite often attacks S. leprosula Miq to its death, but the attack patterns are unknown. This research aims to get data on the frequency, intensity, and patterns of Coptotermes sp. attack in KHDTK Sebulu, East Kalimantan. Methods used were observation, recording, and mapping on S. leprosula Miq trees attacked by termites in KHDTK Sebulu. The results showed that the frequency of termite attacks on S. leprosula Miq in KHDTK Sebulu was 6.4-30.5% and termite attacks intensity was 4.7-22.1%. Termite attack patterns tended to spread and were followed by the formation of the nest to produce colonies.
Keywords : S. Leprosula Miq plant, Coptotermes sp.,attack frequency, attack intensity, attack pattern.
