Diversity of Diurnal Beetles in Banguntapan District Yogyakarta

Abstract

<span>Beetles are insects that have the highest species diversity and abundance of individuals and have various roles in the ecosystem. Changes in land use will certainly affect the diversity, abundance, and dominance of beetles in an ecosystem. This study aims to determine species diversity, species abundance, and individual dominance of beetles, and to compare beetle diversity on non-built land (rice fields and vacant land) compared to built-up land (4 UAD campus and housing). The method in this study is a survey method. Sampling was carried out in October-December 2021 at each sampling location for the UAD 4 campus area, rice fields, housing, and vacant land in Banguntapan District, DIY using <em>pitfall trap </em>planted in the morning and taken in the afternoon, also direct sampling was carried out using bare hand. The beetles that have been obtained are then taken to the laboratory for the identification process. The highest beetle diversity index value was in the rice fields of Banguntapan District, DIY, which was 2,302, while the lowest beetle diversity index value was on campus 4, which was 0.725. The beetle species with the highest species abundance was <em>Gonocephalum </em>sp., while the beetle with the lowest species abundance was <em>Bradycellus</em> <em>nigrinus, Cassida circumdata, Aspidomorpha sanctaecrusis, Verania lineata, </em>and <em>Onthophagus </em>sp. The dominant beetle was <em>Gonocephalum </em>sp., while the less dominant beetle was <em>B. nigrinus.</em></span>
