The recently completed sequencing of the entire genome of the Eurasian spruce bark beetle, Ips typographus, could potentially pave the way for highly specific pest control using what is known as RNA interference (RNAi).

 

RNAi is a molecular biology tool which specifically suppresses the expression of a gene with high precision, by administering double-stranded RNA into the insect, through food for example. This eventually causes the protein production from the corresponding gene to temporarily stop or become reduced, without modifying the genome.

 

The method can provide clear information about the roles played by specific genes in the biology of the bark beetle, a process which is now facilitated by the sequencing of the beetle's entire genome.

 

In the future, it is hoped that the RNAi method will also be usable in practical pest control out in the forests.
