| Abstract | ||||
| This work was carried out at Economic Entomology &Agricultural Zoology Department Faculty of Agriculture, Menoufia University. In order to study the impact of honey bee queens raised from grafted larvae exposed to the magnetic field and the unexposed in some characteristics. Carniolan honey bee hybrid was prepared to be reared from and others to represent the queens. The obtained results in the two seasons indicated that the effect of exposure of grafted queen cups to different times of magnetic field on the acceptance percentages of grafted larvae in beeswax cell cups and differed significantly and ranged from 72.22 to 82.33% for the first year 2017 and from 70, 82.33 % for the second year 2018. The acceptance in 3 days exposure times was significantly higher (82.33%) than the one-day exposure time compared with control. Finally, it could be concluded from the obtained results that exposing grafted queen cell in mass rearing production in honey bee colonies may affect the morphometric characters differed from one day to three days compared with non-exposed colonies, therefore, it could be recommended that beekeeper must be trained to expose his rearing queens in the breeding time to the magnetic field to increase the ability of queens and workers to avoid the bad effects of these radiations | ||||
