Gout disease observed in true firs is introduced by which pest?

Explanation:
Gout disease in true firs is linked to a pest that infests true firs and weakens the trees, often with resinous galls or abnormal growth at shoots. The balsam woolly adelgid is the insect responsible here. It is an invasive, sap-sucking pest that attacks true firs, and its feeding activity is associated with the development of gout-like symptoms in the trees. The other pests listed feed on different hosts (pines or hemlocks) and are not responsible for gout disease in true firs, so they don’t explain this condition.
