تضمن البحث تحديداً لبعض أنواع بعوض تحت الفصيلة Culicinae المنتشرة في جنـوب سـورية، بينت الدراسة وجود 14 نوعاً ثلاثة منها تسجل أول مرة في منطقة الدراسة و تنتمي لجنس Culex هـي: ( Culex perexiguus , Cx. sinaiticus , Cx. territans ). تم وصفها و إيضاحها و بيان صفاتها المميزة، كما درست مواسم التكاثر و النماذج البيئيـة الملائمـة لتكاثرها.
This research concludes an determination of some Culicinae mosquitoes distributed in south of Syria. The study show that there are 14 species, 3 of them were recorded for the first time in the study area, these 3 species were described, illustrated , and distinguished from related species ,the seasonal reproduction and the habitat types of these were studied . (Culex perexiguus , Cx.sinaiticus , Cx.territans).

A study for tribe Coccinellini (Coccinellidae, Coeloptera) was conducted in
south of Syria. The objective of this study was to determine the species and
their relative abundance. Members of this tribe important for biological control
because they
are primariy predators on aphids. The adults Coccinellids were
collected from agriclture and natural ecosystems from August 2001 the end of
July 2003. The results revealed the presence of 10 species belonging to 8 genera.
The investigation included their abundance and distribution in south of Syria.
The species Anisosticta novemdecimpunctata (L.) was recorded in Syria for the
first time. The Adonis ladybird, Hippodamia (Adonia) variegata (Goeze), was
the commonest species. and the most abundant ones were H. variegata (Goeze)
44.9%, Oenopia conglobata (L.) 27.7% and Coccinella septempunctata L.
10.5%.
Since the beginning of the twentieth century, researchers have isolated and
dentified spreaded and adapted yeasts to variow environmental conditions and
the types of the mediums in which they graw. The industrial features of the
isolated genera, e
specially those used in the food processing and the stability of
their genetic characteristics were studied. Yeasts in medical and industrial
fields were also improved.
Primary survey study of the Bryidae has been reported in this
research, whithin range of Biodiversity and Ecodiversity in Syria.
We found ٢٩ species, which has been identified, and defined their
distribution in different places in the north and so
uth of the country,
also the identification of the most important peristome as a scales of
classification, the nature of growth substrates, has been investigated.
Three of these Bryidae recorded for first time which is: Tortella
tortuosa, Grimmia laevigata, Bryum caespiticium.

The concentrations of Copper (Cu) and Zinc (Zn) in samples of some spices
available at some local markets in Syria were determined, after nitric digestion, using
Atomic Absorption Spectrometry. The study showed differences in metal concentrations
according to the edible part. Studied heavy metals were present in all samples at different
levels. The concentration of Copper (Cu) and Zinc varied from trace to higher
concentration. The maximum level of Copper (Cu) in the spices samples was 0.668 mg/kg.
The maximum level of Zinc (Zn) in the spices samples was 2.523mg/kg. The analytical
results obtained for the heavy metals indicate that the Copper and Zinc were present in all
samples at concentration well below the acceptable daily intake recommended by the
World Health Organization.
