- Subject Terms:
- Abstract: This study aimed to evaluate the effect of three insecticides used for the control of insect pests in tomato fields in Quneitra governorate in Syria (deltamethrin, pymetrozine and imidacloprid) on the following predators: Ladybird beetles (Coleoptera: Coccinellidae), Green lacewing (Neuroptera: Chrysopidae) and Nesidiocoris tenuis (Hemiptera: Miridae). The effect of methomyl, acetamiprid and emamectin benzoate on Nesidiocoris tenuis was evaluated 1, 3, 7 and 14 days after spraying pesticides on tomatoes used at the recommended rate by the manufacturer. Experiments were conducted in the field at the Tranjeh and Ayuba Centers in Quneitra in 2015. The results indicated that the use of pesticides reduced the number of predators in the field compared to the control, at different levels. Both deltamethrin and imidacloprid reduced the average number of predators more than that caused by pymetrozine. The reduction rate was as follows: 30.92, 64.29 and 61.93% for eleven-spot ladybird larvae, 19.42, 58.33 and 69.42% for the adult insects of the eleven-spot ladybird, 43.77, 68.79 and 81.26% for seven-spot ladybird larvae, 47.85, 69.62 and 65.19% for green lacewings larvae, and 38.83, 58.90 and 68.40% for insects of the predator Nesidiocoris tenuis when treated with pymetrozine, imidacloprid and deltamethrin, respectively. The reduction rate for predator Nesidiocoris tenuis was 51.62, 68.36 and 75.69% when treated with acetamiprid, emamectin benzoate and methomyl, respectively. The effect of pesticides decreased over time resulting in an increase in the number of predators. [ABSTRACT FROM AUTHOR]
- Abstract: هدفت هذه الدراسة إلى دراسة تأثير بعض المبيدات الحشرية المستخدمة في مكافحة الآفات الحشرية في حقول البندورة/الطماطم في محافظة القنيطرة - سورية Deltamethrin، Pymetrozine و Imidacloprid في مفترسات أبو العيد (Coleoptera: Coccinellidae) المدروسة والمفترس أسد المنّ Chrysoperla carnea (Neuroptera: Chrysopidae) والمفترس (Hemiptera: Miridae) Nesidiocoris tenuis وتأثير Methomyl، Acetamipirid و Emamectin benzoate المفترس Nesidiocoris tenuis، بعد 1، 3، 7 و 14 يوماً من رش المبيدات على البندورة/الطماطم حسب معدلات الإستخدام الموصى بها من قبل الشركة الصانعة للاستخدام الحقلي، وذلك في مركز أمهات طرنجة، ومركز أمهات ايوبا في القنيطرة عام 2015. أشارت النتائج إلى أن استخدام المبيدات قد خفض أعداد المفترسات في الحقل مقارنة بالشاهد ولكن بنسب مختلفة حيث خفض كلا من مبيدي deltamethrin و imidacloprid متوسط عدد المفترسات بنسبة أعلى مما سببه مبيد Pymetrozine. كانت نسبة الخفض كالتالي: 30.92، 64.29 و 61.93% ليرقات أبو العيد ذو الإحدى عشرة نقطة، 19.42، 58.33 و 69.42% للحشرات الكاملة لأبو العيد ذو الإحدى عشرة نقطة، 43.77، 68.79 و 81.26% ليرقات أبو العيد ذو السبع نقاط، 47.85، 69.62 و 65.19% ليرقات أسد المن ّو 38.83، 58.90 و 68.40% للحشرات الكاملة للمفترس Nesidiocoris tenuis عند المعاملة بالمبيدات Pymetrozine، imidacloprid و deltamethrin، على التوالي. وبلغت نسبة الخفض 51.62، 68.36 و 75.69% لعدد المفترس N. tenuis عند المعاملة بالمبيدات Acetamiprid، emamectin benzoate و methomyl، على التوالي. انخفض تأثير المبيدات مع الزمن مما أدى لازدياد أعداد المفترسات.
