bearing rose cultivation areas (11.700 acres)
in Turkey (Tüik, 2018).
Coptotriche
angusti-
collella
was observed during the last half of
May 2017 in a three year old conventional
oil-bearing rose plantation (8 acres), where
one third of the plants were infested. Lar-
vae caused an opaque white gallery becom-
ing a blotch mine on the upper or, occasion-
ally, lower epidermis surface of the leaves
(Figures 1a, 1b). Infested leaf samples were
placed in paper bags and transferred to the
laboratory in cold chain. The leaves were
then placed into plastic boxes (long side
22-cm x 15-cm wide x 15-cm high) and kept
in a climate-controlled room at 25±1°C, 60
% RH, and 16: 8 h photophase: scotophase.
Larvae (Figure 2a) were easily visible with-
in the translucent mines. The pupal stage
was completed in the mines (Figure 2b).
The emerged moths (Figure 2c) were iden-
tified by Dr Erik J. Van Nieukerken and kept
in EMIT (Entomological Museum of Isparta,
Turkey).
After flowering of the oil-bearing rose
(15 May-end of June), observations were re-
peated during post harvest period (July-
October) in the Ardıçlı village at other rose
fields as well as Kermes Oak (
Quercus coc-
cifera
L.) but no damage symptoms were
found. Moreover, no natural enemy was ob-
tained from the infested samples.
