 assist in the weakening or destruction of the trees. It is recommended that very 

 badly infested trees should be destroyed with the insects and that plum orchards 

 should be well cared for in order to keep the trees in vigorous condition and thus 

 render them more resistant to the attacks of the bark beetle.
