Abstract


Secondary peatlands located in Kuala Dua Village, Kubu Raya Regency have various types of insects, one of which dominates is ants. Ants are members of the Order of Hymenoptera which have high diversity and complexity as social animals. Ants play a role in spreading seeds, other insect predators, spore spreaders, decomposers, ecological controllers. Information about the diversity of ants in Kubu Raya Regency is still very limited, especially those on peat land in Kuala Dua Village, Kubu Raya District, therefore research on ant diversity needs to be done with the aim to record the diversity of ants on these peatlands. Laying down the observation path is done intentionally (Purposive sampling). The method used is hand collecting and leaf litter sifting. The results shows that seven genera and four subfamily were obtained. Subfamily found is Formicinae, Ponerinae, Myrmicinae, and Dolichoderinae. The Subfamily Formicinae consists of the genus Camponotus, Colobobsis, Polyrhachis, Anoplolepis. The Ponerinae subfamily consists of the genus Leptogenys. Subfamily Myrmicinae consists of the genus Pheidole. The Dolichoderinae subfamily consists of the genus Ecphorella. The diversity index value on line 1 (1.30) is classified as medium category, line 2 (0.80) is classified as low category and line 3 (0.34) is classified as low category. The abundance index on line 1 (0.80) is classified as high category, line 2 (0.73) is classified as low category, line 3 (0.50) is classified as low category. The similarity index of ant species on line 1 and line 2 are (25%) which classified as low category. Line 1 and 3 are (57.14%) classified as medium category. The similarity index of ant species on line 2 and 3 (40%) were also classified as medium category.Keywords: ants, diversity, Kubu Raya District, peat land.
