简介：
Overview
This article demonstrates novel techniques developed for oral delivery of double-stranded RNA (dsRNA) through the vascular tissues of plants for RNA interference (RNAi) in phloem sap feeding insects. The methods focus on delivering gene-specific dsRNAs to induce RNA interference in vivo and control insect pests.

What is RNA interference?
RNA interference (RNAi) is a biological process in which RNA molecules inhibit gene expression or translation, effectively silencing targeted genes.
How does the oral delivery method work?
The method involves delivering double-stranded RNA through plant vascular tissues, allowing it to reach sap-feeding insects effectively.
What types of insects can this method target?
The techniques demonstrated can target hemipteran pests, such as the brown marmorated stink bug and the Asian citrus psyllid, and may be applicable to other insect types.
What are the advantages of using RNAi-based biopesticides?
RNAi-based biopesticides can provide a targeted approach to pest control, reducing the impact on non-target organisms and the environment.
Is this method environmentally friendly?
Yes, RNAi-based methods can be more environmentally friendly compared to traditional chemical pesticides, as they specifically target pest genes.
What further research is needed?
Further research is needed to optimize the delivery techniques and assess the long-term effects of RNAi-based biopesticides in various agricultural settings.
