RNAi

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 […]

RNAi in Beetles and Leps – Why the Difference?

It is well established that the RNAi response of Coleoptera and Lepidoptera differ greatly but less is known about the basis for these differences.  Skukla et al (2016) systematically investigated this question and report their insights in a recent paper […]

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 […]

Carbon Quantum Dots for dsRNA Delivery

Das et al. (2015) in Applied Materials & Interfaces compare chitosan, silica and carbon quantum dot nanoparticles as dsRNA delivery platforms for silencing genes in larval mosquitoes. Direct injection of dsRNA into the hemocoel of insects has  been somewhat effective […]
