أجريت دراسة حقلية ( بساتين ) ونصف حقلية ( المشتل ) على غراس الحمضيات من صنفي أبو صرة ويافاوي حيث تم استخدام ثلاث مستويات من السماد الازوتي
The objective of this study is to identify some species of mycorrhizal fungi
coexisting with tomato roots in the Syrian coast. Samples were collected from five sites in
two different regions: Lattakia (sites: Siano and ALbrjan) and Tartous (sites:
Majdalon
Elbahr, Mayaar Shaker and Hrysoon). Four samples of soil and tomato roots were
collected from each site and mixed together to form a composite sample/site.
Morphological characterization of isolated fungi was based on universally adopted
taxonomic keys, and on the classification keys approved by the Plant Protection Research
Institute of Iran. Six types of mycorrhizal fungi belonging to 5 species were identified in
the different sites. Paraglomus laccaltum was present in one site (Siano), Septoglomus
constrictum was isolated from 2 sites (Mayaar Shaker and Majdalon Elbahr),
Claroideoglomus etunicatum was also isolated from 2 sites (Mayaar Shaker and Siano),
Simiglomus hoi was present in 3 sites (Siano, Majdalon Elbahr and ALbrjan), Glomus
fasciculatum was present in four sites (Siano, Mayaar Shaker, ALbrjan and Hrysoon) and
Glomus clarum was present in four sites (Hrysoon, Siano, Mayaar Shaker, and Majdalon
Elbahr).
The study was carried out to comparison between of of three controlling treetments,
of soil-borne fungi in greenhouses. The treetments were as follows: An treeted control,
Formalin 3%, soil Solarization + animal manur and solarization for 50 days, and 0 , 5, 10
,15 and 20 cm depth.
This research was conducted in laboratory of Nematology in the Center of Scientific
Agricultural Research in Lattakia, to detection of Entomopathogenic Nematodes (EPNs) in
Citrus Orchards soils in Lattakia governorate.
A total of 66 composite soil
samples were collected from Citrus orchards during (2016-
2017). Entomopathogenic nematodes (EPNs) were recovered from soil samples by the
insect baiting technique, using seventh instar larvae of the Greater wax moth Galleria
mellonella (Lepidoptera: Pyralidae). Infective juveniles (IJs) were collected from G.
mellonella cadavers using the method of White (1927).
EPN isolates were identified based on morphometric methods. Eight isolates were
identified as Heterorhabditis bacteriophora Poinar 1976 (Ord. Rhabditida: Fam.
Heterorhabditidae) .
Positive soil samples ratio was 12.12% of total samples, where EPNs isolates were
extracted from regions (Al-Bassa, Al-Magreet, Al-Shamia, Gio, Al-Kharnoba, Al-Sorsokia,
Fideo, Borj Al-Qasab)0 The soil textures of the EPNs positive samples were (sandy loam,
silt loam, loamy sand, loamy clay sand, clay) with ( pH 6.34- :0.5) and (1.99- 4.82) g\100g
organic content. The electrical conductivity of the nematode positive soils varied from 0.33
to 0.82 ds/m.
A laboratory study was conducted on the parasitoid Citrostichus phyllocnistoides
Narayanan (Eulophidae : Hymenoptera)under average of temperature (18.12± 2.12 Cº)
with Temperature range from 15-23Cº. The final results oflaboratory study indicated t
hat
parasitoid was passed four stages to complete life cycle. The average development time
was: 3.7±0.9 days for eggs – 7.8±0.9 days for larvae,(the time required from the eggs to
hatch and continued untilthelarvae enter the pupal stage 6-10 days) , and12.7±1.03 days for
pupa (the time required from the beginning of pupation to emergence of adult 11-14 days).
The parasitoid needs in average23.3±2.7 days to complete its life cycle. Male longevity
3.8±0.8 days , and female 4.2±0.9 days.
