| الوصف: | Weeds can be important hosts for potential crop pests. Thus, the objective was to evaluate the occurrence of pests in weeds in three crop management strategies. The experiment was conducted in the 2016/17 harvest. Each management had an area of 0.5 ha, used to assess pests: (1) cotton / soybean / Urochloa decumbens; (2) millet / soybean / millet and (3) millet / soybean / Crotalaria. Pest surveys were carried out monthly on weeds during the management of soybean crops and on coverages in succession. Shannow-Weaner diversity, abundance, dominance, frequency and constancy indices and population fluctuation were determined. Fourteen species of pests were identified in association with weeds in the three rotation systems. The order Hemiptera had the largest number of individuals collected, followed by the order Lepidoptera. The millet / soybean / Crotalaria rotation provided the highest number of pests and the cotton / soybean / U. decumbens rotation had the lowest number of pests. The pests Bemisia tabaci, Aphys gossypii and Daubulus maidis presented the largest number of individuals in the evaluations in the three managements. ; Las malas hierbas pueden ser anfitriones importantes para posibles plagas de cultivos. Por lo tanto, el objetivo fue evaluar la ocurrencia de plagas en malezas en tres estrategias de manejo de cultivos. El experimento se realizó en la cosecha 2016/17. Cada manejo tenía un área de 0.5 ha, utilizada para evaluar las plagas: (1) algodón / soja / Urochloa decumbens; (2) mijo / soja / mijo y (3) mijo / soja / Crotalaria. Las encuestas de plagas se llevaron a cabo mensualmente en malezas durante el manejo de los cultivos de soja y en las coberturas en sucesión. Se determinaron los índices de diversidad, abundancia, dominancia, frecuencia y constancia de Shannow-Weaner y la fluctuación de la población. Se identificaron catorce especies de plagas en asociación con malezas en los tres sistemas de rotación. El orden Hemiptera tuvo la mayor cantidad de individuos recolectados, seguido por el orden ... |
