This is a very common pest in

This is a very common pest in conifer plantations with large numbers occuring in the years just after felling - they breed in the stumps and then eat / kill the young trees on replanting. Formerly the young trees were protected by insecticide; now the favoured method, particularly on sites where there will be little weed development, is to leave the site fallow up to 4 years before replanting to allow the weevil population to decline naturally (thus reducing the use of/need for insecticides).
