This study deals with the histological structure of the midgut
of the queen and worker in the Yemeni honey race Apis mellifera
jemenatica Ruttner, 1976. where the results revealed the accuracy
and the miracle of the histological structure of this insect; indeed,
several differences were found out in larvae of queen and worker
as well as in the different ages of each of its stages. The midgut
passes through metamorphosis in different degree of development.
In larval stage we studying 3rd and 5th instar, in case of queen and
worker .Where queen larvae fed with extensive royal jelly in first 3
days only, while in the 5th instar fed with mixed of honey and
breed bee . The results showed that the midgut tissues in the larval
stage was simple in structure at the beginning of its grow, extended
tube and occupy a large space of body, the midgut wall is a simple
epithelium and cover with peritrophic membrane surrounded by
undifferentiating muscles, and separate from hindgut by pyloric
valve. There was differentiation between instar; and within the
same stage. In this study we found that the midgut tissues of larvae
in queen were more advanced than worker.
