اِختُبرت كفاءة بعض المبيدات الحشرية، و المستخلصات النباتيـة فـي مكافحـة خنفـساء الـشوندر البرغوثية خلال الموسمين 2008 و 2009 . عند تقييم ستة مبيدات كيميائية لمكافحة خنفـساء الـشوندر البرغوثية، أظهرت النتائج أن مبيد Cyperino) cypermethrin) أكثر المبيدات فعالية بـ 88.90،% بعـد (% 49.35) diazinonn) Nimadol) بمبيـد مقارنة % 90.69 بـ Cypermethrin مبيد تلاه أسبوعين من المعاملة. بينما وجد عند تقييم أربعة مستخلـصات نباتيـة لمكافحـة خنفـساء الـشوندر البرغوثية، و مقارنتها بالمبيد الحشري Sopreen) cypermethrin-Alpha) أن مستخلص الأزدرخت (.L azedaracht Melia) أعطى أعلى نسبة فعالية (81.60 %) تـلاه أوراق الأصـطرك و أغـصانه 28.44 و 31.35 بــ (Capsicum annuum L.) الحريفـة و الفليفلـة (Styrax officinalis L.) و 56.16 % على الترتيب، و كانت فاعليتها منخفـضة مقارنـة بالمبيـد الحـشري المختبـر Sopreen (55.58 %) بعد 7 أيام من المعاملة. و انخفضت فاعلية المستخلصات مع مرور الوقت بعد المعاملـة مـن 19.63 % بعد 3 أيام إلى 80.51 % بعد 10 أيام من تاريخ المعاملة لمستخلص الأزدرخت. على العكس زادت فعالية المبيد الحشري Sopreen من 67.41 % بعد 3 أيام من المعاملة إلى 57.74 % بعد 10 أيام من المعاملة.
The efficacy of insecticide and plant extracts were tested against beet flea beetle, Chaetocnema tibialis (Illiger) during 2008 and 2009 seasons. Six pesticides were evaluated against beet flea beetle, results showed that Cyperino gave the highest effective percentage (90.88) followed by Cypermethrin (90.69%), in comparison with Nimadol (49.35%) after two weeks of treatment. Four plant extracts were evaluated against beet flea beetle in comparison with Sopreen. Results showed that Melia azedarach L. extract gave the highest effective percentage (60.81) followed Styrax officinalis L. leaves and branches and Capsicum annuum L. extracts by 31.35, 28.44 and 16.57, respectively, in comparison with Sopreen (58.55%) after 7 days of treatment. Percentage of efficacy decreased gradually by increasing the period of exposure after treatment for plant extracts from 63.19% after 3 days to 51.80% after 10 days of Melia azedarach L. extract. Whereas the efficacy percentage of Sopreen increased from 41.67% after 3 days to 74.57% after 10 days of treatment.

Research summary
تبحث هذه الدراسة في فعالية المبيدات الحشرية والمستخلصات النباتية ضد خنفساء البرغوث البنجرية، Chaetocnema tibialis، خلال موسمي 2008 و2009. تم تقييم ستة مبيدات حشرية، وأظهرت النتائج أن Cyperino كان الأكثر فعالية بنسبة 90.88%، يليه Cypermethrin بنسبة 90.69%، مقارنةً بـ Nimadol الذي كانت فعاليته 49.35% بعد أسبوعين من العلاج. كما تم تقييم أربعة مستخلصات نباتية مقارنةً بـ Sopreen، وأظهرت النتائج أن مستخلص Melia azedarach L. كان الأكثر فعالية بنسبة 60.81%، يليه مستخلصات أوراق وفروع Styrax officinalis L. وCapsicum annuum L. بنسبة 31.35% و28.44% و16.57% على التوالي، مقارنةً بـ Sopreen الذي كانت فعاليته 58.55% بعد 7 أيام من العلاج. تراجعت نسبة الفعالية تدريجياً بزيادة فترة التعرض بعد العلاج للمستخلصات النباتية من 63.19% بعد 3 أيام إلى 51.80% بعد 10 أيام لمستخلص Melia azedarach L. بينما زادت نسبة فعالية Sopreen من 41.67% بعد 3 أيام إلى 74.57% بعد 10 أيام من العلاج.
Critical review
دراسة نقدية: تقدم هذه الدراسة معلومات قيمة حول فعالية المبيدات الحشرية والمستخلصات النباتية في مكافحة خنفساء البرغوث البنجرية. ومع ذلك، يمكن تحسين الدراسة من خلال تضمين تحليل أعمق للتأثيرات البيئية المحتملة لاستخدام هذه المبيدات والمستخلصات النباتية. كما أن الدراسة تفتقر إلى مناقشة مفصلة حول الآليات التي تجعل بعض المستخلصات النباتية أكثر فعالية من غيرها. بالإضافة إلى ذلك، يمكن أن تكون هناك حاجة إلى دراسات إضافية لتقييم فعالية هذه العلاجات على مدى فترة زمنية أطول وفي ظروف بيئية مختلفة.

The seasonal activity of beet flea beetle, Chaetocnema tibialis (Illiger), adults
was studied on sugar beet varieties at Homs Region during 2008 season.
Results obtained indicate that the beet flea beetle, Chaetocnema tibialis
(Illiger) adults was
started at the 2nd week of May to all varieties in the 1st and
2nd dates of plantation. The number tended to increase, rather gradually, from
early June reaching peak (65.9 and 97.9 holes/25 leaves) for two dates.
Two peaks occurred during 2008 season, ware as follows:
• The 1st peak occurred in the 4th week and the 2nd week of June (65.9 and
97.9 holes/25 leaves) for 1st and 2nd dates, respectively.
• The 2nd peak occurred in the 4th week of July (118.42 and 364.14 holes/25
leaves) for 1st and 2nd dates, respectively.
The results obtained indicate, that Vico sugerbeet variety was highest
susceptible (50.99 and 116.45 holes/25 leaves) for the 1st and 2nd dates,
meanwhile, Ramona and Prognos were lowest infested. The infestation started
with quite low holes (2.96 holes/25 leaves) at the 3rd week of May and increased
gradually at the 4th week of June with 65.90 holes/leaf, and in end of season
arrived to (118.42 holes/25 leaves). The infestation percentage increased by beet
flea beetle in the 2nd date (the 1st week of February) with twice of infested on
the 1st date (the 1st half of January). Six pesticides were evaluated against beet
flea beetle, results showed that Cyperino pesticide gave the highest effective
percentage (90.88%) followed Cypermethrin by (90.69%), in comparison with
Nimadol pesticide (49.35%) after two week of treatment.
The research was conducted in Al- Mokhtaria Research
Station, Agricultural Research Center, Homs, Syria during season
2016. The efficacy of some plant extracts (Melia azedarach L.,
Schinus molle L., Styrax officinalis L., Eucalyptus camaldulensis
De., Nerium oleander L.) were tested against Stephanitis pyri F.
(Tingidae: Heteroptera) and compared with traditional insecticides
(Cypermethrin, Chlorpyrifos Ethel).
This study was conducted in order to evaluate the efficacy of the aqueous extracts
of three plants (Melia azedarach L., Smilax asepra L. and Styrax officinalis L.),
three pesticides (acetamiprid, abamectin and pyridaben) and releasing of two
preda
tors (Phytoseiuls persimilis Athias–Henriot and Stethorus gilvifrons Mulsant)
in controlling of Tetranychus urticae Koch populations in tomato greenhouse.
The toxic effect of some insecticides (Amitraz, Amitraz + summer oil,
Abamectin, Abamectin + summer oil) and plant extracts (Melia azedarach L.,
M. azedarach + summer oil, Schinus molle L., S. molle + summer oil) were
tested on the predator of pea
r psyllae insect Anthocoris nemoralis F. and the
parasite Trechnites psyllae R. in the Mokhtaria research station, agricultural
research center at Homs during the season 2011.
This investigation carried out in 2012-2013,in department of plant protection-
Damascus Unv., to study the effect of ethanol and water extracts of Allium sativum L.,
Inula viscos L., Thymus vulgaris L. and Melia azedarach L., in inhibition mycelium
growth of fungi Alternaria alternata and Fusarium oxysporum and compared with
fungicides (carbendazim and chlorothalonil) on PDA in the laboratory. The result showed
that ethanol extracts of studied species gave significant inhibition to growth fungi
compared with the control. The ethanol and water extract of the Allium sativum gave the
superior effect inhibition to F. oxysporum where gave 100% inhibition at 600 and 1000
mg/l. at respectively, and gave100% inhibition to A. alternata at 1000 mg/l. Followed with
the ethanol extract of Inula viscos. While, the ethanol and water extract of the Melia
azedarach gave the lowest inhibition to growth study fungi. Where didn’t gave 100 %
inhibition to F. oxysporum and A. alternata at 1000 mg/l. On the other hand, the ethanol
extract of Thymus vulgaris gave moderate inhibition to F. oxysporum, while the inhibition
of A. alternata was little. The ethanol extract of tested plants gave the superior effect
inhibition to both fungi compared with water extracts. On the other hand, the obtained
results showed that carbandazim gave the superior inhibition for F. oxysporum ,where gave
100% inhibition at concentration 120 mg/l. While the fungicide chlorothalonil gave the
lowest inhibition to F. oxysporum. At contrast, the fungicide chlorothalonil gave the
highest inhibition to A. alternata at used concentration. Where cause 100% inhibition at
150 mg/l. On the other hand, Effect of plant extracts and fungicides increased with increase
of concentrate. We can arranged the effect of plant extraction at the values (ED50): Allium
sativum L., Inula viscos L., Thymus vulgaris L. and Melia azedarach L., Therefore we
recommended to use the ethanol extract of the Allium sativum L., Inula viscos L. as
environment friendly fungicides.
