This research was conducted in a field of wheat located at Suran
(20 kilometers to the north of Hama city). The aim was to study
the influence of wheat planting date on wheat stem sawflies
infestation levels.
The research showed that the early wh
eat seeding led to
breaking the synchronization between the sensitive wheat
development period suitable for the wheat stem sawfly infection and
the existence of the insects in the fields.
