Abstract

Ants include the order Hymenoptera and the Formicidae family, ants are easily recognizable even though there are other insects that are very similar. Ant colonies are divided into three castes, queen, male and worker. The queen is larger than the other castes usually winged, although the wings are dropped after the marriage process. This study aims to record the diversity of ant species (Formicidae) and compare the types of ants (Formicidae) in Mangrove vegetation (Rhyzopora sp) and Nipah (Nypa fruticans) in mangrove forests in Podorukun Village, Seponti District, North Kayong Regency. The research method uses purposive sampling method with the placement of observation paths determined based on considerations by taking into account the physical and biological conditions that influence the presence of ants in the field. The observation path was made as many as 4 lanes for two types of vegetation types, namely Nipah (Nypa fruticans) and Bakau (Rhizopora sp) vegetation, each of which contained two observation paths. The study was carried out using traps, placement of traps used in each lane, including: lower strata, highest tide limits, middle strata of trees, and upper tree strata. Based on the results of the study showed the number of genus, species and number of individual ants, in the nipah (Nypa fruticans) vegetation there were 6 genera and 8 species. The highest number of genus obtained was Euprenolepis, the highest number of species was Euprenolepis procera and the number of individuals who were captured was 714 individuals. The location of observation on mangrove vegetation (Rhyzopora sp) contained 5 genera and 6 species, the highest number of genus obtained was Crematogaster, the highest number of species was Crematogaster reticulata and the number of individuals caught was 615 individuals.
