This study was carried out to determine the biodiversity of rodents and their distribution in Syrian Arab Republic, and to evaluate the role of owls as natural enemies against rodents. The investigation of owl pellets indicated that small mammals in general and especially rodents are the main food of owls. This investigation was able to identify ١٤ species, representing five families of rodents inside the pellets collected from different locations in Syria. these are: Microtus socialis.; Mesocricetus auratus; Cricetulus migratorius; Tatera indica; Mus musculus; Rattus norvegicus; Rattus rattus; Nesokia indica; Meriones tristrami; Meriones libycus; Meriones crassus; Allactaga euphratica; Jaculus jaculus and Spalax leucodon.

A trial to control codling moth, Cydia pomonella L., by releasing the egg
parasitoid Trichogramma cacoeciae Marchal, was conducted for the first time
at Syria in Al-Sweida Mountains, ٢٠٠١. This experiment was carried out in a
young commercial appl
e orchard in Jabal Urman, Sweida. T. cacoeciae (Sy٢
strain) was released two times at a rate of ١٥٠ parasitoids/ tree/ release.
Efficacy in reduction of fruit damage was ٣٤,٣٧٪ comparing with untreated
one. Results showed that ٢ applications of this rate at the second generation
were not efficient to prevent damage above the economic threshold but it could
be used as a part of an integrated pest management program of this pest.
Several factors that affect Trichogramma efficacy in the field are discussed.
