Weather–Population Interactions of the Alien Pest Fall Armyworm (Spodoptera frugiperda): Field Evidence from Two Seasons

Key Points

• Fall armyworm populations vary significantly with changing weather patterns, affecting crop damage levels.
• Observations show that during wet conditions, population density increased by 40% compared to dry conditions.
• Analysis of field data across two seasons reveals strong correlations between insect activity and climatic variables.
• Findings highlight the need for adaptive pest management strategies in agriculture due to climate variability.
