DNA insecticides as an emerging tool for plant protection and food security strategies

A large number of plant diseases and damages are caused by insects and insect vectors of plant pathogens, leading to the serious threats facing plant protection and food security. The access to safe and nutritiously high-quality food is essential for human growth and development. This translates to a well-developed society with systematically organized efforts for maintenance and increased food production or supply to meet the continuous growing demand. The effects of environmental, biological, chemical, political and socioeconomic factors have all contributed to the present nature of food dynamics, its availability, supply and security. Hence, the development of safe bio-based substances should be prioritized for precise and effective use in plant protection strategies. This review examines the sequential results of the insecticidal potentials of unmodified short single-stranded DNA fragments used as DNA insecticides, and emerging tool for safe plant protection strategy.
