Abstract
The newly emerged F, hybnd workers had the highest mean weights for the
head and thorax either fresh or dry. The Carniolan race came next, while the Syrian
workers had the lowest weights in spring and summer. The hypopharyngeal glands
showed a similar trend in their development after feeding the newly emerged workers
for ten days on candy centaininp 10% of pollen grains. The F1 hybrid workers showed
the highest rate of development, followed by the Carniolan race The lowest mean
was recorded in those of the Syrian race. Some major elements, namely Potassium
(K). Calcium (Ca), Sodium (Na) and Magnesium (I\o\g) in the heao of the newly
emerged workers of the Syrian and Carniolan races and their F1 hybrid .n spring and
summer seasons were determined by Atormc absorption techniques The statistical
analysis proved strongly that there were Significant difrerences between the honeybee
workers reared in spnng and summer in their content of the (K). (Cal, (Na) and (Mg) In
the three tested bees
Concerning to the thorax fresh weight, dry weight and nitrogen content for
each tested bees during the two seasons Statistical analysis indicated that there were
Significant difrerences between the means of the two races and their F 1 hybrid In
spring and summer. Only one exception occurred in the case of nitrogen content of
the Carniolan race.
