Arthropods were identified by order and family and typified by functional groups. Diversity and abundance indices by pasture and season were estimated, as well as their correlation with climate. A simple correspondence analysis was performed. <strong><span class="CharOverride-5">Results. </span></strong>A total of 380 insects from 7 orders and 35 families were collected, with the greatest abundance for Hemiptera and Coleoptera. The Shannon’s diversity index was higher for all orders of <em><span class="CharOverride-6">C. gayana</span></em>, except for Hemiptera in <em><span class="CharOverride-6">C. ciliaris</span></em>. Phytophages were found in a higher percentage (66.84 %), followed by predators (27.11 %). Insect abundance was influenced by the interaction between season and pasture, showing an increase at low temperatures, except for <em><span class="CharOverride-6">M. maximus</span></em>. Pastures represented adequate microenvironments to maintain the diversity of insects, the Hemiptera and Coleoptera orders being the most numerous and representative of the functional groups of phytophages and predators, respectively. <strong><span class="CharOverride-5">Conclusion.</span> </strong>The entomofauna of <em><span class="CharOverride-6">C. gayana</span></em>, <em><span class="CharOverride-6">C. ciliaris</span></em>, and <span class="CharOverride-6"><em>M. maximus</em> </span>was similar in insect abundance and diversity, however, insect abundance depended on the influence of the season and pastures.</p>}, number={2}, journal={Agronomía Mesoamericana}, author={Sierra-Baquero, Paola Vanessa and Sánchez-Doria, Tatiana and Burbano-Erazo, Esteban}, year={2023}, month={Jan.}, pages={50757} }
