Bacteria-Mediated RNA Interference for Management of Plagiodera versicolora (Coleoptera: Chrysomelidae)

open access: yesInsects, 2019
RNA interference (RNAi) has emerged as a novel and feasible strategy for pest management. Methods for cost-effective production and stable delivery of double-stranded RNA (dsRNA) to the target insects are crucial for the wide application of RNAi for pest

Evaluating the potential of RNA interference for control of striped cucumber beetle, Acalymma vittatum (Fabricius) (Coleoptera: Chrysomelidae)

open access: yesPest Management Science, EarlyView.
SCB has a robust RNAi response to injected dsRNA, but oral RNAi is less efficient. Nucleases do not appear to be responsible for the discrepancy, suggesting other factors are involved. Abstract BACKGROUND The striped cucumber beetle (SCB) is a serious pest of cucurbit crops, causing damage both by feeding on plants and by vectoring plant diseases ...
