In the SAFEbugBeads project, we are working in a research network on the field application of RNAi technology to control harmful bugs. One focus is in the brown marmorated stink bug (Halyomorpha halys), which causes considerable damage to crops, particularly in fruit growing and horticulture, and for which there is currently no effective control strategy. 

​

The aim of the project is to test and optimize the practical suitability of RNA-based plant protection products. A particular focus is in the development of stability mechanisms for the applied dsRNA under field conditions, especially against rain and UV radiation. The use of alginate-based attract-and-kill capsules containing both RNA and attractants is intended to increase the efficiency, stability and selectivity of RNAi agents. These innovative capsules enable targeted uptake of the dsRNA active ingredients by the pest bugs, resulting in a long-lasting protective effect.
