Scanning electron microscope (S.E.M.) was used to investigate some sensilla organs of honey bee workers and drones antennae infested with varroa mites. Mean numbers and surface area of Sensilla placodea and mean number and length of Sensilla Trichodea type A & B for samples of healthy, heavily infested and deformed newly emerged workers and drones with varroa mites were conducted by S.E.M. Mean number and mean surface area of sensilla placodea on flagellomeres no. 6,8,10 of the examined bee

There were reducing significant in the average no. of sensilla trichodea type A and B of antennae among the infested and healthy newly emerged honey bee workers particularly in the deformed worker bees. Significant lowers of mean length, width and mean surface area of antennal flagellomer were found in the heavily infested and deformed worker and drone bees than the healthy ones.
