The research was conducted to study an efficacy of the fungus
Trichoderma harzianumin controlling the gray mold disease on
tomato that causing by the fungus Botrytis cinerea. A local isolate
of the fungus T. harzianum was studied under laboratory conditions
using two methods: antagonism and the spore suspension.
The research has carried out at the Faculty of agriculture entomology lab.
and agriculture research center at Duma . Samples have been collected from
wax frames infected with Galleria mellonella (Lepidoptera: Pyralidae) From
Damascus, Damascus rural areas, Qunytera, Daraa and Tartus Governorats,
for three years (١٩٩٩ – ٢٠٠١).
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.
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.
