Abstract

Coptotermes genus a subterranean tennite from the family Rhinotennitidae, is one of the the important pests in Malaysia because it causes 90% damages in buildings and structure and gives economically impact annually. The problem raised when there are difficulties for Coptotermes identification that essential for proper pest management as the Coptotermes itself showed the continuous variation within the single species populations. Thus, the phylogenetic analysis using mitochondrial DNA sequences (COIl mtDNA) was used to construct the phylogenetic relationship tree of Coptotermes species and to evaluate the phylogenetic relationship between the Coptotermes species. The maximum likelihood, maximum parsimony and neighbour joining trees of these species were also included. The available sequences for these species from GenBank were included.C.gestroi seems to be very close to C.travians morphologically and the genetic distances are between 1.1 % to 1.3%. However, this current study required more samples of Coptotermes spp. from various locations to confirm the phylogenetic relationship. The molecular approach for Coptotermes identification believes to resolve the taxonomy identification problems among the researchers worldwide that help to improve the tennite management strategies.
