title: The effects of RNA interference targeting Bactrocera dorsalis ds-Bdrpl19 on the gene expression of rpl19 in non-target insects.
abstract: Double-stranded RNA (dsRNA) designed to target pest genes emerges as a promising strategy for improving pest control. Therefore, it is necessary to assess the effects of dsRNA on non-target insects, such as native enemies and beneficial insects, to determine the environmental safety of such treatments. In this paper, we investigated the effects of dsRNA targeting rpl19 from Bactrocera dorsalis on non-target insects in citrus ecological systems by feeding the dsRNA to Bactrocera minax, Apis mellifera and Diachasmimorpha longicaudata. The results showed that when B. dorsalis were fed rpl19 CDS dsRNA or 3'UTR dsRNA, the expression of rpl19 was dramatically decreased. Feeding the Bdrpl19 CDS dsRNA to adult B. minax and D. longicaudata caused their respective rpl19 genes to be knocked down over 50-70 and 40%, respectively, but it had no effect on the expression of the rpl19 gene in A. mellifera. The Bdrpl19 3'UTR dsRNA did not have any silencing effects on the expression levels of rpl19 in non-target insects. This study provides evidence that dsRNA can impact non-target organisms, but the 3'UTR dsRNA may not have effects in non-target organisms.
