ABSTRACT Clove plants (Syzygium aromaticum L. (Merr & Perry) in Indonesia are approximately 95% cultivated by the people in the form of smallholder plantations spread across all provinces. The remaining 5% are cultivated by private plantations and state plantations. A survey conducted by the Unsrat Faculty of Agriculture team in 2016 to early 2017 on clove plantations in Pinolosian District and Central Pinolosian District, found stem borer beetles that attack clove trees, resulting in the death of plants aged around 5-20 years in several clove plantations (Watung et al., 2020). n this study, low diversity and activity of beetles (Coleoptera) in certain habitats were found, influenced by environmental factors such as rainfall and host plant species. The main objective of this study was to analyze the diversity and dominance of beetle communities (Coleoptera) and to determine the influence of environmental factors on beetle activity. The methods used included collecting beetle data using color traps and lure compounds made from ethanol and alpha-pinene, as well as statistical analysis in the form of analysis of variance (ANOVA) to measure differences in treatments and environmental factors. The results showed 12 beetle families were found, with Curculionidae as the dominant family and the diversity index value was in the medium category. ANOVA analysis showed that the three treatments did not differ significantly. The conclusion of this study is that the diversity and activity of beetles (Coleoptera) are influenced by environmental factors, and climatic conditions and the dry season support the diversity of beetle communities (Coleoptera). Therefore, this study is recommended to be implemented in the dry season for optimal results and to support the ecological management of beetles in related habitats.
