RCdE publishes original research articles, essays, scientific notes, book reviews and obituaries related to the area of insect science in English and Spanish. It also publishes review articles on general entomological topics, called "thematic reviews", however, these are only done by request of the Editorial Committee.</p> <p>The journal focuses on papers in the area of entomology and related fields such as biodiversity, ecology, agriculture, human, veterinary and forensic medicine, physiology, systematics and taxonomy, biogeography and genetics that fall within the following topics:</p> <ul> <li>Agricultural entomology.</li> <li>Ecology and behavior.</li> <li>Insect growth and development.</li> <li>Insect anatomy and insect physiology.</li> <li>Systematic entomology.</li> <li>Medical, veterinary and forensic entomology.</li> <li>Microbiology and molecular entomology<strong>.</strong></li> </ul> <p>For details see Instructions for authors.</p> <p>Submitted articles should not be previously published and are subject to double-blind peer review. The journal requires payment from authors at the time of publication. Fees vary according to the number of published pages (with a special discount fee for SOCOLEN members).</p> https://revistacolombianaentomologia.univalle.edu.co/index.php/SOCOLEN/article/view/12822 2025-07-31T15:46:04-05:00 Vitor Oliveira Santiago vitoroliveira1998@gmail.com Enilton José Bernardes Júnior enilton.bernardes@gmail.com Ednaldo Cândido Rocha ednaldo.rocha@ueg.br Flávio Gonçalves De Jesus flavio.jesus@ifgoiano.edu.br Marco Antônio Oliveira marco.oliveira@ufv.br Márcio da Silva Araújo Araújo marcio.araujo@ueg.br

<p><span style="font-weight: 400;">This study examines the structure of epigeic and arboreal ant communities in fragments of Seasonal Semideciduous Forest (SSF) and surrounding matrices (soybean and corn crops and fallow fields) in the Brazilian Cerrado. Ants were collected using baited traps placed along transects perpendicular to the forest fragments. Species specificity and habitat fidelity were evaluated using the indicator species index (IndVal). Environmental variables such as fragment size, litter quantity, and edge proximity did not significantly affect ant richness in SSF. However, non-parametric multidimensional scaling revealed clear differences in community structure between habitats (soil and canopy in SSF, and soil in matrices), and among the three land use states in the matrix (soybean, corn, or uncultivated). Rarefaction curves showed higher ant richness in SSF fragments, in soil and trees. Species composition differed across land uses, in the agricultural matrices, although overall richness did not vary significantly. Based on IndVal, five ant species were identified as indicators of SSF soil, and four as indicators of matrix soil. These patterns demonstrate how land use influences ant communities. Since ants perform vital ecological functions, such as nutrient cycling, seed dispersal and soil structuring, changes in their composition can reflect underlying shifts in ecosystem processes. The presence or absence of specific ant species thus serves as a reliable signal of environmental quality. This reinforces the value of ants as effective bioindicators and highlights the importance of conserving native forest fragments amid expanding agricultural landscapes.</span></p>

<p><span style="font-weight: 400;">Stored grain pests differ in their feeding behavior and damage potential. This study evaluated the comparative impact of three key storage pests of wheat </span><em><span style="font-weight: 400;">Tribolium castaneum</span></em><span style="font-weight: 400;"> (Coleoptera: Tenebrionidae), </span><em><span style="font-weight: 400;">Trogoderma granarium</span></em><span style="font-weight: 400;"> (Coleoptera: Dermestidae), and </span><em><span style="font-weight: 400;">Sitophilus oryzae</span></em><span style="font-weight: 400;"> (Coleoptera: Curculionidae) under controlled laboratory conditions. Homogeneous-age insects were introduced separately for each species into vials containing 2 grams of whole wheat grains, with three replicates per species, as experiments were conducted independently for all three species. After 35 days, data were recorded on insect survival, number and weight of damaged grains, number and weight of undamaged grains, and percent weight loss. </span><em><span style="font-weight: 400;">S. oryzae</span></em><span style="font-weight: 400;"> exhibited the highest mean number of live insects (16.67), followed by </span><em><span style="font-weight: 400;">T. granarium</span></em><span style="font-weight: 400;"> (9.89) and </span><em><span style="font-weight: 400;">T. castaneum</span></em><span style="font-weight: 400;"> (6.67). </span><em><span style="font-weight: 400;">S. oryzae</span></em><span style="font-weight: 400;"> also caused the most grain damage (21.33 damaged grains) and the most significant weight loss (16.75 %), followed by </span><em><span style="font-weight: 400;">T. castaneum</span></em><span style="font-weight: 400;"> (8.56 grains, 2.07 %) and </span><em><span style="font-weight: 400;">T. granarium</span></em><span style="font-weight: 400;"> (2.56 grains, 0.74 %). Regression analysis revealed a strong relationship between insect number and weight loss for </span><em><span style="font-weight: 400;">S. oryzae</span></em><span style="font-weight: 400;"> (R² = 0.57) and </span><em><span style="font-weight: 400;">T. granarium</span></em><span style="font-weight: 400;"> (R² = 0.46), but a weak relationship for </span><em><span style="font-weight: 400;">T. castaneum</span></em><span style="font-weight: 400;"> (R² = 0.0044), likely due to its lower survival and superficial feeding behavior. These findings provide comparative insights into species-specific damage patterns and may inform more targeted post-harvest pest management strategies.</span></p>
