Diversity of orthoptera of Bukit Bauk Forest Reserve, Terengganu

Abstract

Bukit Bauk Forest Reserve, Terengganu noted for its richness in the flora and fauna with high degree of endemicity for some species. The study was conducted at Bukit Bauk Forest Reserve, Terengganu to examine and compare the diversity of Orthoptera. From this study, a total of 106 specimens of Orthoptera have been documented and identified, representing 9 species from 5 families of Orthoptera. Suborder Caelifera found out to be more abundant than Ensifera, with Tettigidea lateralis (Tetrigidae) and Gryllus bimaculata (Gryllidae) being most abundant species recorded. Physicals factors measured (light intensity, temperature and relative humidity) were not differed between elevations. The abundance of Orthopterans was not associated with elevations within the study site. More extensive study should be conducted to provide clearer evidence of taxonomical status of Orthopteran in the study site. Factors that may contribute to Orthoptera diversity and abundance are also discussed.
