The unique Yew-and-Boxwood Tree Grove in Sochi, Russia, is having a bad time as nearly all local boxwood trees (Buxus colchica) were destroyed by Cydalima perspectalis larvae which feed on boxwood tree leaves. The moth was supposedly brought in amidst some Italian plants imported for landscape works to decorate the area of the 2014 Winter Sochi Olympics. They tried to liquidate pest once it was spotted but it hardly got any result.
Experts say now about 70% of boxwood trees are totally destroyed by the moth invasion. The thing is getting worse due to that C. perspectalis has overspread along the whole Black Sea coastline. Moreover, there are no natural enemies that could restrain pest population to some extent.
It's reported that a new insecticide is currently being developed. The nature reserve authorities sent a request to the Ministry of Nature asking for a permit to use special insecticides banned in other nature reserves in order to save the rest of boxwood trees.
