Special Issue Information

Dear Colleagues,

Agricultural pests have posed a significant challenge to global food security, with their adaptive evolution and resistance mechanisms complicating integrated pest management strategies. This Special Issue aims to explore the latest advancements in understanding these complex dynamics, focusing on research that addresses the adaptive evolution of pests in terms of pesticides, plant resistance, and other pest management strategies. We seek original research articles and reviews that contribute to the understanding of pest resistance mechanisms, the role of adaptive evolution in pest populations, and innovative approaches to overcoming these challenges. By showcasing the latest scientific findings, this issue aims to foster interdisciplinary collaboration and inform future pest management practises.

The fall armyworm (Spodoptera frugiperda) is a significant agricultural pest with a broad host range and adaptability, posing challenges to pest management worldwide. To elucidate the molecular mechanisms underpinning their development and resilience, we performed a comprehensive transcriptomic analysis across nine developmental stages, spanning from the first instar larvae to adult forms. Utilizing differential expression analysis and time-series clustering, we identified 6834 differentially expressed genes (DEGs), uncovering key stage-specific expression patterns. Notably, 3072 stage-specific genes (SSGs) were defined using the Tau index, highlighting their roles in development and physiological adaptation. Functional enrichment revealed that the sixth instar stage prioritizes pathways related to growth and tissue remodeling, while adult males emphasize reproductive and sensory functions. Furthermore, we characterized 104 cytochrome P450 (P450) genes, showcasing distinct temporal expression patterns critical for detoxification and metabolic processes. A tandem array of P450 genes on chromosome 13 was identified, suggesting a coordinated mechanism enhancing insecticide resistance. Our findings highlight the complex genetic regulation that facilitates the developmental transitions and adaptive capabilities of S. frugiperda. These insights offer potential molecular targets for innovative pest management strategies aimed at mitigating the widespread impact of this pest. Full article
