Diagnosis

Fund. juv. only with spinal and marginal wax pore plates; wax pore plates on inner margins of meso- and metathoracic spinal sclerites divided into 3–4 often angular areas with relatively large pits of irregular shape. Al. gallicola: wax glands on head and prothorax of granular appearance, without or with a few indistinct facets. Galls like those of A. nordmannianae   but are usually larger (7–22 mm) and open in June–July. Holocyclic and dioecious, alternating between Picea orientalis   and Abies   (see also p. 21).

Recorded primary hosts

Pinaceae   : Picea orientalis   .

Distribution

S.

A8 (A7) Wax glands of overwintering larvae with double-walled facets secreting glossy, stiff, straight or curved tubes of wax; galls usually with protruding needles and hairs or waxy bloom ................................................................................................................................A9

A9 (A10) Overwintering larvae (where known): dorsal sclerites bearing single larger wax pores ringed by small glands of irregular shape. Al. gallicola: ant. IV and V often with broad, indistinct basal articulation .................................................. Adelges (Adelges) Vallot, 1836
