Raising Predatory Insects on Farms as Biological control for Combating Parasit

Abstract

Predatory insects are essential agents in sustainable agriculture, offering an eco-friendly alternative to chemical pesticides by naturally regulating pest populations. This review examines their ecological roles, taxonomic diversity, predation strategies (including extraguild and intraguild predation), and practical applications in Integrated Pest Management (IPM). Key species such as ladybugs (Coccinellidae), lacewings (Chrysopidae), and ground beetles (Carabidae) effectively control pests like aphids, whiteflies, and soil-dwelling insects. Despite their benefits, challenges such as high rearing costs, environmental sensitivity, and limited farmer adoption persist. Solutions include improved mass-rearing techniques, habitat enhancement, and farmer education. By integrating predatory insects into agricultural systems, farmers can reduce pesticide reliance, enhance biodiversity, and promote long-term sustainability. Future research should focus on optimizing predator-prey interactions and expanding their use in diverse agroecosystems.
