Achieving sustainable agriculture in the face of environmental degradation and climate change demands innovative and integrative approaches. This article explores the convergence of biodiversity conservation, biological control strategies, and modern genomic tools to enhance agroecosystem resilience in Vietnam and comparable regions. We examine the role of native biodiversity in supporting natural pest regulation, the application of classical and augmentative biological control methods, and how genomic technologies-such as DNA barcoding, environmental DNA (eDNA), and gene editing-can improve pest and natural enemy identification, monitoring, and deployment. Through case studies from Vietnam, we demonstrate how locally adapted, biodiversity-based solutions combined with genomics can reduce pesticide reliance, protect ecosystem services, and contribute to climate-smart agricultural practices. The article highlights the importance of interdisciplinary collaboration and capacity building to scale these innovations across Southeast Asia and globally.

In Southeast Asia, agriculture plays a critical role in the economy, yet it faces significant challenges from pests, invasive species, and environmental degradation. Effective pest management and agroecological innovation are essential for improving crop yields and ensuring sustainable agricultural practices. This article explores multi-scale approaches that integrate genetic, ecological, and socioeconomic perspectives to address pest management and agroecological innovation in the region. By combining advances in pest taxonomy, ecological monitoring, and cutting-edge technologies, the study highlights innovative strategies for pest control and management, ranging from molecular techniques to field-based interventions. We emphasize the importance of understanding pest dynamics at various scales, from the genetic level of pest resistance to field-level practices that promote biodiversity and soil health. Furthermore, the article discusses the role of local knowledge in shaping effective, contextspecific solutions and the need for cross-disciplinary collaboration among scientists, farmers, and policy-makers. The study concludes by outlining key opportunities for integrating pest management with broader agroecological strategies, including the promotion of agro-biodiversity, ecosystem services, and sustainable practices that ensure food security and environmental resilience in Southeast Asia.

The intensification of agriculture has led to increased reliance on chemical pesticides, raising concerns about environmental degradation, pest resistance, and human health. In response, this study explores the efficacy and integration of two biological and agroecological pest control methods-Metarhizium anisopliae, an entomopathogenic fungus, and the augmentorium, a physical containment structure designed to recycle natural enemies while preventing pest escape. Through a mixed-methods approach involving field trials, laboratory assays, and farmer interviews across three agroecological zones in Southeast Asia, we assess the viability of these interventions as components of sustainable pest management strategies. Results indicate that M. anisopliae achieved a 60-75% reduction in target pest populations (notably Spodoptera frugiperda and Bactrocera dorsalis), while augmentoria retained over 80% of parasitoids and predators introduced to control fruit fly populations. Farmers reported increased yields and reduced pesticide use, though challenges related to initial setup costs and limited technical knowledge were noted. The findings support a synergistic approach that combines biological agents with agroecological infrastructure, offering a resilient alternative to chemical-intensive pest control. Policy implications highlight the need for training, extension services, and support for locally adapted biocontrol innovation. Methodology Research Design This study employed a mixed-methods research design, combining quantitative field trials and laboratory experiments with qualitative interviews and participatory observation. This approach enabled both the empirical measurement of pest suppression outcomes and an understanding of

Agroecological innovation has emerged as a transformative approach to achieving sustainability in agricultural systems, particularly in the face of environmental degradation, climate change, and food security challenges. This article explores the role of agroecological practices in fostering sustainable agriculture by integrating ecological principles with innovative farming techniques. By emphasizing biodiversity, soil health, water conservation, and local knowledge, agroecology offers a holistic framework for addressing the complex interconnections between agriculture, ecology, and society. The paper reviews key agroecological innovations, including agroforestry, crop diversification, integrated pest management, and the use of organic fertilizers, highlighting their potential to enhance resilience and reduce the environmental footprint of food production. Through case studies and empirical evidence, this article also examines the socioeconomic impacts of agroecological practices on rural communities, including improvements in livelihoods, food security, and community empowerment. Ultimately, it argues that agroecological innovation is critical for advancing long-term sustainability in agriculture, urging policymakers, farmers, and stakeholders to embrace these practices as a pathway toward a more sustainable and equitable food system.
