Andricus multiplicatus
Giraud, 1859
Host plants.
Israel
:
Q. libani
. Elsewhere:
Q. brantii
,
Q. cerris
,
Q. trojana
.
Life history.
Known only from the bud galls of the sexual generation, which are multi-chambered, often aggregated leafy rosettes,
25–40 mm
in diameter, with numerous larval chambers at the bases of the rosette leaves (
Fig. 67
). Old galls remain on the tree for a year.
Phenology.
Galls begin to develop in May, at which time the rosette is bright green. Adults emerge from them in June, after which the gall turns brown and dries out.
Distribution.
Israel
: Mt. Hermon,
1780 m
.a.s.l. Eleswhere: common from South-central Europe to
Turkey
.
Comments.
This gall resembles that of
A. cydoniae
Giraud
, which is unknown from
Israel
and develops on the same oak hosts. However, the galls of
A. cydoniae
are genuinely multi-chambered, with many larval chambers inside a single solid mass of tissue, rather than an aggregation of distinct galls. In Europe,
A. multiplicatus
is known from
Q. cerris
but we did not find it on this host plant in
Israel
. The morphology of the galls on the different host plants in
Iran
and Europe is similar to that of the Israeli galls on
Q. libani
.
