Abstract EN

A survey to identify economic insects of poplar trees was carried out during 1993-1995 at Euphrates region in Syria.

Various sampling techniques were used to collect different stages of insects from all tree parts (roots, stems, branches and leaves).

The survey revealed the presence of 24 insect species belonging to 8 orders and 17 families, including three species reported on poplar for the first time in Syria; Pemphigus bursarius L., Scipteron tabanformis Rott., Polyphylla fullo L.

The intensity of infestation varied from location to another depending on tree age and agricultural practices.

These insect species were divided into two groups: crop insect pests, comprised of 15 species and insect predators, comprised of 9 species
