اختبرت سمية الرماد الناتج من حرق بقايا التقليم لثلاثة أنواع نباتية: التفاح، العنب، الزيتون ضد بالغات خنفساء اللوبياء العادية Callosobruchus maculatus (F.) (Coleoptera. Bruchidae) باستخدام خمسة تراكيز (5 و10 و20 و40 و80) غ/كغ بذور لوبياء. نُفذت الدراسة ضمن الحاضنة عند درجة حرارة و رطوبة نسبية ثابتة في مركز بحوث التقنيات الحيوية بجامعة البعث. أُخذت القراءات بعد (24 و48 و72) ساعة من المعاملة، و حُسبت نسب القتل المصحّحة و قيم كلاً من: LC50 وLC90 وLT50 وLT90.
Ash toxicity of burning pruning residues of three plant species i.e. apple, grape and
olive was tested against adults of cowpea seed beetle Callosobruchus maculatus
(F.) (Coleoptera, Bruchidae) using the following concentrations: (5, 10, 20, 40
and 80) g/kg of cowpea seed. The study was carried out in incubator at fixed
temperature and humidity at Biotechnology Research Center, Al-baath University.
Readings were taken after (24, 48 and 72) h of treatment, and corrected mortality
rates were calculated and values of LC50, LC90, LT50 and LT90.
