Abstract EN

This study is conducted by using strain of hybrid local honeybees Apis mellifera L.

from 20th of April to 20th of July 2016 in Wassit Provence / Al-kut city.

This study aims at discovering the effect of magnetic food on the activity of honey bee colonies and improve their production in the spring and summer seasons .

Three magnetic power are treated in this study (1000, 2000, 3000) Gauss.

The results show that honeybee colonies fed with magnetized food are significantly higher in both open and closed incubation brood, and are higher in density compared to natural feeding.

For the open brood area, the magnetic food treatments G 2000 and G3000 exceed 3024.57 and 3382.67 cm2 respectively.

The lowest comparative treatment is 2772.81 cm2 / hive, the treatment G 3000 exceed the treatments G 1000 and 2000 G and the treated G 1000 as an average brood area open is 2908.75 cm2 / hive, Similarly, closed brood area for workers the magnetic food treatments 2000 G and G3000 are 2792.12 and 3205.91 cm2 / hive respectively, while the comparison treatment is 2533.14 cm2 / hive, and the treatment G 3000 exceed the treatments G 1000 and G 2000 Where treatment 1000 G give the average closed brood area of 2652.78 cm2 / hive.

Density is the highest for G 2000 and G 3000 are 13.17 and 14.12 frame / hive respectively, while the lowest comparison treatment is 10.59 frame / hive.
