dc.descriptionForage sorghum, valued for its high protein content and resilience to abiotic stress, is key component in livestock feed production. However, it faces challenges from various insect pests such as aphids, fall armyworms, and sugarcane borers. This study investigated insect dynamics, focusing on Melanaphis sorghi, and their interactions with natural enemies, weather patterns, and other pests in forage sorghum cultivation. Conducted over two seasons crop in Brazil, the research compared plots with and without insecticide treatment, employing weekly insect sampling and climate monitoring. Our findings revealed M. sorghi as the predominant pest, with populations peaking during the vegetative stage. Correlation analysis showed a positive relationship between M. sorghi and Syrphidae predators, with weaker associations observed for Spodoptera frugiperda. The prevalence of Rhophalosiphum maidis increases in the second season, influenced by rainfall. Predatory insects like Coccinellidae and Syrphidae contribute to pest population control. Untreated areas exhibit higher diversity and equitability, indicating a balanced pest-predator ecosystem. Principal component analysis (PCA) suggested that the climate and specific pests exert an influence on treated areas, suggesting potential resistance or the need for more refined control strategies. This study underscores the importance of understanding pest dynamics for sustainable agriculture, providing valuable insights for the integrated pest management strategies to mitigate economic losses.
