Entomovectoring: a green technology for crop protection
摘要
Entomovectoring, the use of foraging behavior of insects to deliver biological control agents directly to crops, has emerged as a sustainable and ecofriendly alternative to chemical pesticides. Pollinators such as honey bees (Apis mellifera), bumble bees (Bombus sp.), and mason bees (Osmia sp.) are the most widely studied vectors, with fungi, bacteria, and viruses formulated in optimized carriers serving as control agent. This review synthesizes findings from over four decades of entomovectoring research, critically examining the mechanisms, vectors, dispenser devices, and microbial agents employed in the technology. Comparative analyses of dispenser devices depicted that two-way dispensers generally achieve greater efficiency in vector loading and has reduced inoculum loss in comparison with to one-way dispenser devices. Further key challenges in maintaining consistent inoculum transfer under field conditions, vector-agent compatibility, behavioral avoidance, and environmental variability were addressed in detail. Regulatory considerations and knowledge gap regarding long-term ecosystem impacts, vector health, and efficacy across diverse cropping systems are discussed in the aim of integrating entomovectoring with Integrated Pest Management frameworks. By consolidating current knowledge and identifying research gaps, the current review provides a foundation for advancing entomovectoring as a scalable, green technology that bridges pollination services with crop protection.
