    For sap-sucking insects, such as sharpshooters, aphids, whiteflies and psyllids, dsRNA delivery methods have been demonstrated [29,42,49,50]. In the present study, we demonstrated the induction of specific RNAi effects in ACP by oral acquisition of dsRNA from artificial diets and M. paniculata leaves.

Silencing of JHEH and EcR genes of Plutella xylostella ...

    https://www.sciencedirect.com/science/article/pii/S122686151630259X
    RNAi through oral delivery of dsRNA is elucidated in P. xylostella. • JHEH and EcR were chosen as target genes for silencing. • Target gene silencing resulted in mortality which is reliant on dsRNA concentration. • JHEH and EcR proved to be good target genes in bringing out pest management.

    Second, limiting factor of dsRNA was determined through oral administration. Third, to prevent dsRNA degradation and supply large amounts of dsRNA, a recombinant bacterial expression system was used to produce dsRNA. Fourth, bacterial delivery system was modified to facilitate dsRNA release from recombinant bacteria.

Practical Use of RNA Interference: Oral Delivery of Double ...

    The oral delivery of dsRNA is particularly interesting for the application of RNAi in a pest control strategy, but a method to retard the degradation of dsRNA by the nucleases in the midgut has not yet been developed, which would have the potential to ensure effective RNAi through feeding.

Delivery of lethal dsRNAs in insect diets by branched ...

    https://www.sciencedirect.com/science/article/pii/S0168365918300208
    Delivery is in the form of dsRNA/BAPC complexes. The biophysical properties of the dsRNA/BAPC complexes are very similar to the BAPCs-DNA complexes previously reported . BAPCs mixed with dsRNA form compact clusters with sizes ranging predominantly from 70 to 500 nm and with zeta potentials ranging from 10 to 18 mV.

    We showed that oral delivery of bacterially expressed dsRNA would lead to RNAi effects in the recipient insect. Quantitative real-time PCR results showed that expression level of target MseChi1 and MseChi2 genes in gut tissue of M. separata were down-regulated after oral delivery of engineered bacteria expressing the corresponding dsRNA.
