festations by
H. armigera
on flowers of
R
.
damascena
in Aglasun-Burdur and Atabey-
Isparta, Turkey (Figures 1, 2). During May and
June 2010, 53 oil-bearing rose orchards were
inspected and four of them were found in-
fested. Larvae of
H. armigera
were collec-
ted from flowers of
R
.
damascena
in differ-
ent localities, which are listed in Table 1. All
the collected specimens were moved into a
growth chamber
at 26±1ºC and 60% relati-
ve humidity and fed daily with fresh oil-be-
aring rose flowers. Both laboratory and field
observations have displayed that the pest
attacks principally carpels and stamens and
less petals. Furthermore,
H. armigera
larvae
were observed feeding on dried rose pe-
tals located on drying racks in rose oil facto-
ries. These rose petals were being dried for
personal use and the feeding activity of the
pest affected their value. As
H
.
armigera
is a
pest having world-wide distribution, the oil-
bearing rose growers and agricultural advi-
sers need to be alerted and the potential risk
posed to the oil-bearing rose crop should be
considered.
I would like to thank Dr Alberto Zilli (Muse-
um of Zoology, Rome, Italy) for identification
of Cotton Bollworm. Special thanks to Dr Ser-
kan Boyar (Suleyman Demirel University, Fac-
ulty of Agriculture, Department of Agricultur-
al Machinery, Isparta, Turkey) for his contribu-
tions in this study. And another special thanks
to Kara Tyler Julian (University of Florida, IFAS-
North Florida Research and Education Center,
Quincy, Florida-USA) for language assistance.
