Deregulation of Colorado beetle in Russia
Leptinotarsa decemlineata (A2 quarantine pest), the Colorado beetle, has been deleted from Russia's revised list of quarantine pests. The reason is the great increase in the area of distribution of the pest in Russia, which has changed from relatively restricted to almost ubiquitous in potato-growing areas. While action against spread of the pest will no longer be taken nationally, regional authorities may still impose restrictions in areas still free from the beetle.
