Critical review
دراسة نقدية: تعد هذه الدراسة مهمة لفهم التغيرات الفصلية لمجتمعات الأكاروسات في بساتين التفاح، ولكن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الممكن توسيع نطاق الدراسة لتشمل مناطق أخرى في سوريا للحصول على نتائج أكثر شمولية. ثانياً، لم يتم التطرق بشكل كافٍ إلى تأثير العوامل البيئية الأخرى مثل التربة والرياح على توزيع الأكاروسات. ثالثاً، كان من الممكن استخدام تقنيات تحليل بيانات أكثر تطوراً للحصول على نتائج دقيقة. وأخيراً، كان من الممكن تقديم توصيات أكثر تفصيلاً حول كيفية تطبيق أساليب الإدارة المتكاملة للآفات بشكل عملي في البساتين.

The accuracy of the taxon T. cinnabarinus (Boisduval 1867) as a distinct species, or
as a synonym of Tetranychus urticae Koch 1836, is still standing as a controversial issue of
taxonomy and as a point of discussion. T. cinnabarinus and T. urticae
have been regarded
in the first stage of this study as one species, and it was characterized depending on the
distinctive characteristics of both genders. In the second stage, the two species were
distinguished according to many morphological characters that have been recommended by
authors cited T.cinnabarinus as a valid species. The efficiency of some measures adopted
to distinguish both T. cinnabarinus and T. urticae were also tested. Measurements didn't
match local samples that showed obvious differences, T. cinnabarinus & T. urticae are not
likely to be considered as two different species according to recent researches. Both T.
cinnabarinus and T. urticae were detected on various wild and cultivated host plants. One
hundred samples of plants presented symptoms of tetranychid attacks were collected from
different localities in Lattakia province. Both T. urticae and T. cinnabarinus were found on
29, 9 samples, respectively.
Biological characteristics and life table parameters of the two-spotted spider mite Tetranychus urticae (Koch) were studied when fed on leaves of two apple cultivars (i.e. Golden and Starking dilishz) under laboratory conditions 25±1 Cº, relative hum
idity 65±5% and 16L:8D. The intrinsic rate of increase (rm) by females of T.urticae was higher on leaves of Starking dilishz apple cultivar than on leaves of Golden dilishz apple cultivar (0.30, 0.27 female/female/day) respectively, while the generation time (T) and the time required for doubling the number of community mite (DT) were lower on leaves of Starking dilishz apple cultivars than on leaves of Golden dilishz apple cultivars (13.77, 2.3 days and 14.54, 2.55 days) respectively. The duration of the stages of growth from egg to adult female on leaves of Golden dilishz apple cultivar was longer than on Starking dilishz apple cultivars, where was (13.32 ± 1.15 and 12.22 ± 1.13), respectively, The Total fecundity on Golden dilishz apple cultivar was lower than on Starking dilishz cultivar (83.11 ± 8.91, 101.62 ± 15.48 eggs/female) respectively, The adult longevity on Golden dilishz leaves was lower than on Starking dilishz cultivar (15.33 ± 1.35, 17.14 ± 1.07 days) respectively, These differences on the apple varieties may be due to the chemical content and quality of the food and nature of the host tissue plant and the specifications can affect the rate of oviposition and development. and thus the Starking dilishz apple cultivars was more suitable for the development and reproduction of T. urticae compared with the Golden dilishz apple cultivar.
In this experiment, liquid of soap at three dosages (3, 5 and 7 ml/L) and
Abamectin (12.5 ml/100L) has been used with releas of the mite predator,
Phytoseiulus persimilis for controlling the two-spotted spider mite, Tetranychus
urticae on bean pla
nts under laboratory conditions. Contact toxicity of soap
liquid and Abamectin were evaluated and classified according to IOBC.
Efficacy of soap liquid at 3 and 5 ml/L was not sufficient to repress spider mite
populations while the using of soap liquid at three concentration with
predatory mite showed supporter effect and provide satisfactory control
whereas soap liquid determined to be slightly harmful- moderately to P.
persimilis. Abamectin with predatory mite or if used only gave sufficient control
to spider mite population but without supporter effect between Abamectin and
predatory mite whereas Abamectin determined to be harmful to P. persimilis.
However, using soap at suitable dosage, with or without predatory mite, gave
encouraging results for controlling spider mites. Generally, using of soap
showed adaptation with predatory mite and proved supporter effect for
controlling the spider mites. In despite of, soap showed no phytotoxicity to host
plants but needs to be tested in greenhouse and field conditions before
application.
This study is concerned with the variations in annual and seasonal surface
air temperature in Syria, depending on the data from 12 different
meteorological stations in Syria.
The analysis of surface temperature trends was performed using Least
sq
uares (linear regression) and Moving- averaging filters according to
Gaussian low- pass filter.
Fast Fourier Transformation was used for the analysis of periodicity for the
annual mean surface temperature.
The results of linear regression showed that the general trend of annual and
seasonal temperature in all stations was positive except Latakya.
The results of annual and seasonal temperature, fluctuations revealed the
existence of important warming period in all stations starting from 1993-1994
for the average of annual and winter temperature while summer, autumn and
spring temperatures averages were above the mean during the study period.
Periodicities analysis showed that the surface air temperature seems to be
affected by solar cycle and quasi- biennial oscillation as well as the El-nino
southern oscillation.
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.
