Aylax papaveris
is one of the three Cyn-
ipidae species inducing capsule galls in
P.
rhoeas
,
P. dubium
,
P. argemone
L. and
P. som-
niferum
L., the other two species being
Bar-
botinia oraniensis
(Barbotin) and
Aylax mi-
nor
Hartig, 1840 (Pujade-Villar, 2015; Gómez
et al
., 2017).
Aylax papaveris
forms light yel-
low fused galls, irregular oval or globular
in shape, highly variable in size, including
a few dozen larval chambers arranged per-
pendicularly to the vertical capsule axis. The
individual gall chambers originate from the
transformation of the septum and seeds,
usually causing deformation and enlarge-
ment of the capsules (mainly in
P. rhoeas
and
P. dubium
). Internal septa and seeds disap-
pear (Pujade-Villar, 2015).
Dasineura papav-
eris
is a monophagous bivoltine gall midge
of
Papaver
spp. capsules, which have a nor-
mal appearance after infestation and only
when opened the clearly swollen septa are
visible (Skuhravá and Skuhravý 1997; Pope-
scu 2002).
In the capsules from Voeotia, we en-
countered galls by the cynipid gall wasp
A.
papaveris
(Figure 2) and the parasitoids
Idi-
omacromerus
spp. (three male specimens,
probably
I. papaveris
, although it is difficult
