        Even though plant protections using chemical pesticides have several advantages, non-specific toxicities to other beneficial insects and humans and rapid development of tolerance and/or resistance of target pests to chemicals are major disadvantages. Recent researches suggested that using double stranded RNA (dsRNA) could be species specific and environmental friendly pest management protocols. However, efficiency of dsRNA treatments are known to be variable according to its application methods. For example, injections of dsRNAs to pests were known to be effective in all species. However, efficiencies of oral application of dsRNAs were known to be dependent on species. Thus, development of tools that could enhance the efficacy of orally treated dsRNAs are utmost important for widening usages of dsRNAs in plant protection. Recently, we found that the efficacy of oral treated dsRNAs to target pests could be enhanced by nano-technologies. I will show how applying nano-technology to dsRNAs enhance the efficiency of dsRNAs.
