Abstract

Studies on the insect fauna of peat swamp forest ecosystems in Sabah are lacking. With looming threats of habitat destruction and biodiversity losses as a result of expanding agricultural conversion and the incipient drainage and fire hazards in the surrounding peatlands it is vital that as much biological information is obtained to enable holistic formulation of conservation plan for Klias Forest Reserve KFR. Knowledge of the insect diversity and abundance will provide important link to an understanding of the ecological functions of insects as decomposers pollinators food sources population regulators and soil engineers. The insect survey of KFR and its adjacent areas could generate requisite information on the conservation significance of the insect groups their relation to human as pests their medicinal uses and potentials for ecotourism as well as present scientific evidence to the planning authorities of the pivotal link to maintaining environmental balance. The survey grouped the insect into six main taxa namely Coleoptera beetles Odonata dragonflies Lipidoptera butterflies homoptera cicadas and bugs Hymenoptera ants and Orthoptera grasshopers katydids and crickets. Being a pioneering efforts the overall results constitute the only known record of insects for KFR. Comparison to other earlier documented works was also attempted. In the peat swamp environment insects do not play a major role in decomposition. Insects that favour succulent vegetation and are normally associated with human food crops such as Orthoptera were encountered more in the open areas rather than forested environment. In the village due to presence of food crops more ladybird and leaf beetles were present. The results indicate that despite the poorer plant diversity the peat swamp forest harboured a fairly high number of butterfly species. Butterflies are known as good pollinators.
