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%.
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, illustrate
d , and
distinguished from related species ,the seasonal reproduction and the habitat
types of these were studied .
(Culex perexiguus , Cx.sinaiticus , Cx.territans).
This research was carried out on six climatic stations: Damascus, Daraa, As-Suwayda, Quneitra, Southern Ain al-Arab, and Sergaya in order to analyze the phenomenon of frost in the southern region. The minimum temperature was used to study this phenomenon for a period of time that reached thirty years.
