دراسة إمكانية تكامل المستحضر الحيوي ثيورين مع المبيد الكيمياويجنتابرايد للسيطرة على حشرة مَّنْ الخوخ الأخضر Myzus persicae

Abstract EN

This study aimed to find program of Integrated Pest Management consisted of biological control element representative by the bio-preparation Thurin with combination of the pesticide Gentabride to control the green peach aphid Myzus persica. The bio-preparation Thurin and pesticide Gentabride revealed a good effect against the adult of green peach aphid.

Thurin caused mortality rate about 24 % at the concentration 5 ml/l (preached dose) besides the pesticide Gentabride caused mortality rate reached to 36% at the concentration 0.5 ml/l\ (preached dose). The study showed in agreement between the bio-preparation and pesticide when the mixed together with the pesticide Gentabride (half and quarter doses) that give good tolerance to the pesticide on Nutrient Agar .the density of bacteria ranged between (217 x and 222 x ) colony forming unity / ml.

at (0.25 and 0.5) ml \ L , concentration respectively.

while the control treatment was 231 x colony forming unity / ml.

as well as the integration formula proved high efficiency on the average of mortalities of the green peach aphid which resulted in a 51.22 % mortality.

When compared with the bio-preparation and the pesticide (35.73 and49.6 ) % respectively. The result of laboratory experiments showed all the concentration of treatments, cause a good mortality rate on the green peach aphid.

as well as whole the treatments (the bio-preparation ,chemicide Gentabride and integration formula) showed ability on the average of mortalities of the green peach aphid range among (22.76 –52.22)% , (38.38 – 62.14)% and (39.89 – 65.06)% respectively.
