Abstract
Baculoviruses represent a promising group of microbial insecticides for the biological control of agricultural pests, particularly those within the order Lepidoptera. Their high host specificity and environmental safety make them ideal candidates for inclusion in integrated pest management (IPM) programs. This review presents a comprehensive overview of baculovirus biology, highlighting their infection mechanisms, selectivity, and ecological compatibility. Special attention is given to advances in mass production systems—both in vivo and in vitro—and formulation technologies that improve field efficacy and environmental persistence, including UV protectants and microencapsulation. Regulatory aspects are also discussed, comparing international approval pathways and highlighting the disparity between regions with supportive policies (e.g., Latin America, Asia) and those with more restrictive frameworks (e.g., the European Union). Additionally, the current global market landscape for baculovirus-based products is examined, with emphasis on recent growth, commercialized formulations, and challenges such as host resistance and the limited spectrum of action. By synthesizing findings from the scientific literature and industry reports, this review underscores the role of baculoviruses as effective, sustainable alternatives or complements to chemical insecticides in modern agriculture, contributing to the reduction in pesticide residues and environmental impact.
