Abstract

 
The monthly average weights of pollen grains collected at three trap types along (Mar. 2018 / Feb. 2020) were conducted at  apiaries of Carniolan hybrids of Elsharkia Governorate: Diarb Nigm , Abokabeer  and Kafr Sakar.  Statistical analysis of the 1st year revealed that there were no significant differences in the weights of pollen grains by 1st and 2nd  type of traps , where it was 365.8, 360.8 , 357.5 g /trap / colony, for  1st  type of traps  at  Diarb Nigm  ,  Abokabeer  and Kafr Sakar, respectively, and  it was 337.4, 336.2 , 335.4 g , for  2nd  type of traps , respectively , while there were significant differences in the weights  of pollen grains between 1st & 2nd  and 3rd  type, where it was 258.1, 256.0 , 255.0 g /trap / colony, for  the 3rd type of traps , respectively. Statistical analysis the 2nd year revealed that there were no significant differences in the weights of pollen by 1st and 2nd  type of traps , where it was 364.1, 360.0 , 355.0 g /trap / colony, for 1st type of traps  at the three sites, respectively, and  it was 337.9, 335.8 , 334.5 g, for  2nd  traps, respectively , while there were significant differences in the weights  of pollen grains between 1st & 2nd  and 3rd type of traps , where it was 257.1, 256.2 , 254.2  g , for  the 3rd type of traps , respectively.
