Andricus moreae
(
Graeffe, 1905
)
Host plants.
Israel
:
Q. boissieri
. Elsewhere:
Q. pubescens
and
Q. infectoria
.
Life history.
Known only from the bud galls of the asexual generation. These are spherical, single-chambered galls,
10 mm
in diameter, resembling a blueberry, with a small apical ‘crown’. They are found on the terminal parts of branches, usually in small clusters, dark green, turning brown and very hard when mature (
Fig. 18
). Old galls remain on the tree for several years and turn darker. The similarity of this species to host-alternating
Andricus
species suggests that if a sexual generation exists, it induces galls on oaks from section
Cerris
(e.g.
Q. cerris
,
Q. brantii
,
Q. libani
).
Phenology.
Galls develop quickly from early to late August and the adults emerge from them in
Israel
in September-October (elsewhere also in November). In other countries where this species is known, some of the adults overwinter inside the galls and emerge in March of the following year.
Distribution.
Israel
: Mt. Hermon
1500 and
1780
m.a.s.l., Odem Forest, Allone HaBashan, Mt. Addir. Elsewhere: Geece,
Turkey
,
Syria
,
Lebanon
,
Iran
.
Comments.
This species has not been collected for many years following its original description and its status was uncertain (
Bellido
et al.
2003
). However, recently, many galls were found and adults were reared from
Greece
,
Syria
and
Iran
(
Kwast 2005
;
Azizkhani
et al.
2006
), as well as during the present study.
The general shape and phenology of these galls resemble those of
A. sternlichti
(
Fig. 20
) but
A. sternlichti
galls are much bigger, pale brown when mature, and have typical pointy protuberances connected by ridges, which are absent in the much smaller and darker brown galls of
A. moreae
.
