<![CDATA[This study aims to analyse the diversity and dominance of insect species in maize fields in Caturharjo Village, Sleman District, Yogyakarta. The research was conducted from March to August 2025 on 1,000 m² of maize fields divided into three plots, each measuring 10 × 15 m. Light traps were installed in the centre of each plot, and insects were captured manually (direct capture) every three days. Species diversity was calculated using the Shannon-Wiener Index, dominance using the Simpson Index, and the data were analysed for correlation with abiotic factors. The results showed that the total number of insect individuals in the vegetative phase of maize plants was 19,874 individuals, consisting of 6 orders, 24 families, and 30 species. The largest proportion of insects were predators (33.33%), followed by herbivores (26.67%), maize pests (16.67%), visitors (10%), detritivores (10%), and pollinators (3.33%). The insect diversity index was (H') = 0.83, which was classified as low diversity, and the dominance index was (D) = 0.18, indicating low dominance. The conclusion of this study is that the insect species diversity at the study site was low, with no dominant species found, and a total of 30 insect species found.]]>
