Abstract
This study was carried out in Apiary of the Faculty of Agriculture, Kafr El-Sheikh University during the period from February 2017 to February 2018. eighty four different combs age from 1 to 7 years old were distributed in twelve colonies each have seven combs, colonies headed by young sister queen , sample was taken from the center of each comb and compare with standard sample taken from comb wax built without foundation wax, result showed that weight of comb , exuviae and height base of the hexagonal cell were significantly positively correlation with age of comb also the cell diameter, depth of cell and volume of the cell were significantly negatively correlation with age of comb. Weight of newly emerged workers and all morphological measurements were significantly negatively correlation with age of comb.
Area of mandibular gland , acini in Hypo pharyngeal glands (HPG) and area of the second wax gland were significantly negatively correlation with age of comb.
for brood production results showed that brood production differed and significantly affected by comb age, the largest worker sealed brood area was recorded in new combs compare with old combs. Also weight of honey yield was significantly negatively correlation with age of comb.
The largest mean area of drawing the foundation wax recorded in colonies fed twice a week compare with colonies fed once a week, the largest amount of built workers cells recorded in May and June and the largest area of built drone cells was recorded late March to mid-April.
