Genetic Dissection of RNAi in the Colorado Potato Beetle, Leptinotarsa decemlineata

RNAi works well in beetles, in general, and why that is is not all that clear but Yoon et al. (2016) have begun to identify key genetic contributors in their recent paper in Insect Biochemistry and Molecular Biology.  The authors […]

Post-feeding and -injection Dynamics of dsRNA in 4 Insects

The variability of dsRNA-induced RNA interference is well documented with some insects very amenable to this method of regulating gene expression while are others are very much less so. The factors involved in this variation are known to some extent […]

Lipoplexes and oral dsRNA delivery to Blattella germanica

Lin et al., in Pesticide Management Science have described their efforts to orally deliver dsRNA to the German cockroach, Blattella germanica. Blattella germanica is fairly sensitive to RNAi when dsRNA is injected into the hemocoel.  Directly feeding B. germanica dsRNA […]

Extreme Transgenerational Gene Silencing

Abdellatef et al. (2015) recently published the results of their efforts to silence the salivary sheath protein gene in the aphid Sitobion avenae in the Plant Biotechnology Journal and observed what might be called extreme transgenerational gene silencing. Plant-expressed dsRNA […]
