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 […]

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 […]

Parental RNAi Via Oral Delivery

Khajuria et al (2015) have published a short paper in Insect Biochemistry and Molecular Biology describing their observations supporting the idea that Diabrotica vigifera exhibits parental RNAi following the oral delivery of dsRNA. Parental RNAi (pRNAi) refers to an inter-generational […]

Plastid Mediated RNAi: A Novel Insecticidal Tool

Recently, Zhang et al demonstrated a robust and promising way of controlling the devastating solanaceous crops insect pest, Colorado potato beetle (Leptinotarsa decemlineata; CPB), using a modified strategy for delivering plant mediated RNAi. Increasing insect herbivores’ resistance to plant defense mechanisms […]
