DOI: 10.1002/arch.21640
Abstract: Long noncoding RNAs (lncRNAs) that have immune responses to various stimuli have been identified in some insects. One type of pathogen-associated molecular pattern, double-stranded RNA (dsRNA), can trigger the RNA interference (RNAi) pathway and immune… read more here.

DOI: 10.1002/ps.6017
Abstract: BACKGROUND The southern green stinkbug, Nezara viridula (Hemiptera: Pentatomidae), is an important emerging polyphagous pest infesting soybean in the United States, Brazil and Argentina. The indiscriminate use of synthetic insecticides to control stinkbugs has limited… read more here.

DOI: 10.1002/ps.6949
Abstract: BACKGROUND Phytophthora. infestans is a late blight-causing oomycetes pathogen. It evolves and adapts to the host background and new fungicide molecules rapidly within a few years of their release, most likely due to the predominance… read more here.

DOI: 10.1002/ps.7076
Abstract: BACKGROUND Previous studies have found that pesticide dsRNA usually has a long-lasting validity period in plants. However, it is uncertain if any factors in plants could extend dsRNA duration. It has been reported that RNA-dependent… read more here.

DOI: 10.1002/ps.7322
Abstract: BACKGROUND RNA interference (RNAi) technology has been considered as a promising pest control strategy due to its species selectivity. One of the popular RNAs is exogenous double strand RNA (dsRNA). However, dsRNA is easily degraded… read more here.

DOI: 10.1016/j.pestbp.2021.104853
Abstract: Lepidopteran insects are highly refractory to oral RNA interference (RNAi). Degradation, impaired cellular uptake and intracellular transport of double-stranded RNA (dsRNA) are considered the major factors responsible for the reduced RNAi efficiency in these insects.… read more here.

DOI: 10.1016/j.str.2020.04.016
Abstract: Non-enveloped icosahedral double-stranded RNA (dsRNA) viruses possess multifunctional capsids required for their proliferation. Whereas protozoan/fungal dsRNA viruses have a relatively simple capsid structure, which suffices for the intracellular phase in their life cycle, metazoan dsRNA… read more here.
