Tiny beetle wreaks havoc on Texas ornamental tree nurseries

...rees, 1 to 3 years old, the infestation most often proves fatal. Mature trees are more likely to survive the infestation but may serve as staging base for the beetle to attack nearby younger trees. For this reason, the general control strategy is to cut down and destroy any infested trees immediately. If l...
