Andricus curtisii
(
Müller, 1870
)
Host plants.
Israel
:
Q. boissieri
.
Elsewhere:
Q. infectoria
.
Life history.
Known only from the bud galls of the asexual generation, which develop from lenticel (accessory) buds on the trunk and well-established branches. These are big, striking galls,
20–40 mm
in diameter, composed of pyramidal units that form a spherical structure, pinkish, with a velvety cover (
Fig. 11
), and contain a single central chamber embedded in spongy tissue. Old galls remain on the tree for several years. Molecular data suggest that the sexual generation of this species develops in cryptic bud galls currently attributed to the
Andricus burgundus
complex (
Stone
et al
. 2008
).
Phenology.
The galls develop through the summer and mature by late September-early October. In
Israel
, adults emerge from January to early February, whereas in Europe they usually emerge in spring.
Distribution.
Israel
: Odem Forest, En Zivan, Allone HaBashan, Tel Hazeqa, Rehan Forest. Elsewhere: a locally common eastern-mediterranean species known from
Croatia
,
Greece
, Southern
Italy
,
Turkey
,
Iran
, West Azarbaijan,
Kurdistan
and
Algeria
.
Comments.
The galls of this species cannot be mistaken for any other gall in
Israel
. They resemble the galls of
A. hartigi
Hartig
on
Q. petraea
,
Q. pubescens
and
Q. robur
in Europe and
Asia Minor
but
A. hartigi
galls are covered by detachable spines whereas
A. curtisii
galls are velvety.
