The experimental design was randomized blocks, with five treatments, consisting of the DeltaOPAL, FMX 966, FMX 993, FMX 910, and NuOPAL cultivars, in four replications. Among the arthropods sampled in the cotton crop, the coccinellids and spiders were the most abundant ones in the cultivars evaluated. Spiders occurred throughout the cotton cycle, while the coccinellids population increased gradually until 55 DAE, showing a population peak at 34 DAE, coinciding with the population peak of aphids (<em>Aphis gossypii</em>). Among the coccinellids observed in the cultivars under study, <em>Scymnus</em> spp. was the most abundant in cotton. The pentatomid and forficulid occurred from 99 to 128 days after the emergence of cotton, which corresponds to the highest density of target pest insects. It was not found influence of meteorological factors or negative interactions among predaceous arthropods. </span></span></span></p> <p style="margin-bottom: 0cm; font-style: normal; font-weight: normal; line-height: 120%; text-decoration: none;" lang="en-US" align="JUSTIFY"><span style="color: #000000;"><span style="font-family: Times New Roman,serif;"><span style="font-size: small;">KEY-WORDS: <em>Gossypium hirsutum</em>; natural enemies, coccinellids.</span></span></span></p><br><p style="margin-bottom: 0cm; font-style: normal; font-weight: normal; line-height: 120%; text-decoration: none;" lang="pt-BR" align="JUSTIFY"><span style="color: #000000;"><span style="font-family: Times New Roman,serif;"><span style="font-size: small;">Com o objetivo de estudar a abund&acirc;ncia e a diversidade de artr&oacute;podes predadores associados &agrave; cultura do algodoeiro e analisar a influ&ecirc;ncia de fatores meteorol&oacute;gicos, intera&ccedil;&otilde;es entre inimigos naturais e a din&acirc;mica populacional de coccinel&iacute;deos associados &agrave; sua principal presa, o pulg&atilde;o <em>Aphis gossypii</em>, um experimento foi realizado na regi&atilde;o de Ipameri (GO), no Campus da Universidade Estadual de Goi&aacute;s.
