Abstract
The present study was carried out to evaluate the affect of some supplementary feeding on longevity and hypo pharyngeal glands of caged honey bee workers . The experiment was performed in the apiary and laboratories of Agricultur Faclty of Assiut, EL - Azhar University, during 2005 season.
The tested diets were: tow parts corn flour + one part + defatted soya bean flour tow parts bean flour- one part + date paste: one part skimmed milk
10 % Prewer,s :three parts chick pea flour + one part skimmed milk bee - bread The data could be summarized as follows:
The full time for the tested diets was the longest (31 days) for the bees fed on bee bread followed by that composed of 10% brewers : three parts chich pea flour: one part skimmed as the survival period recorded (24 days) .
The longevity of caged bees fed on the mixtures consisted of tow parts corn flour+one part deffated Soya been flour was (18 days) while other bees lived shorter periods (15 days) when fed on diet consistes of tow parts bean flour: one part dute paste: one part skimmed milk.
The development of the hypo pharyngeal glands increased gradually since emergence of the workers until reaching the maximum measurements on 6-12 th day of worker age.
It was found that the workers fed on bee bread gave the highest mean acinal surface area followed by that composed of 2 parts corn flour: 1 part deffated Soya been flour then that composed of 2 parts bean flour : 1 part date paste : 1 part skimmed milk.
While the lowest acinal surface area was detected in caged bees fed on 10 % brewers: 3 part chick pea flour+ 1 part skimmed milk.
Generally , the workers fed on bee bread was the best in both cases (the longevity of caged bees and development of Hypo pharyngeal glands of caged bees ).
