MARPHOMETRICAL STUDIES OF SOME ANTENNAL SENSOR ORGANS OF EGYPION AND CARNIOLAN HONEYBEE WORKERS

This study compared the ultrastructure of some sensor organs on the antennae of egyptian, apis mellifera lamarckii, bees to that of carniolan, a. m. carnica, bees. egyptian bees is the endemic bee of egypt and is well adapted to the local conditions and pests of the region. second stock was a large population of honeybees and is maintained commercially in egypt. the following characteristics were compared: the antennal length; the number and the measurements of sensilla of placodea, trichodea and chaetica of the flagellomeres 1 to 8 of the antennae of workers of the two honeybee races was studied by scanning electron microscopy. there was a highly significant difference between the antennal length of egyptian and carniolan honeybee workers (p=0.0097)with means of 3.858 ± 0.162 mm. and 4.321 ± 0.076 mm.respectively. statistically, the numbers and the measurements of sensor organs of the antennae of egyptian and carniolan honeybees did not deffer from one another in most flagellomers.
