Sperm Utilization

ABSTRACT Sperm usage by queen honey bees was examined by progeny analyses using six phenotypically distinct genetic markers. No evidence was found for sperm displacement or precedence. All queens used the sperm of all males that inseminated them during all sampling periods. Sperm usage, as measured by phenotypic frequencies, did fluctuate nonrandomly but did not result in abnormally high representation of a single phenotype or the elimination of other phenotypes as has often been suggested. The genetic relationships of workers within honey bee colonies are estimated from the data presented. Average genetic relatedness is shown to be low among colony nestmates and probably approaches 0.25 in colonies with naturally mated queens. There is no evidence for elevated relatedness among colony subfamilies due to nonrandom fluctuations in sperm usage by queens or for numerical dominance of any subfamilies.

Adult Worker

In addition to the compound eyes, honeybees have three dorsal ocelli on the vertex of the head. Each ocellus has about 800 elongated photoreceptor cells. They are paired and the distal segment of each pair bears densely packed microvilli forming together a platelike fused rhabdom. Beneath a common cuticular lens a single layer of corneagenous cells is present.Ultrastructural studies were made of the retina of praepupae, different pupal stages and adult worker bees by thin sections and freeze-etch preparations. In praepupae the ocellar anlage consists of a conical group of epidermal cells that differentiate to photoreceptor cells, glial cells and corneagenous cells. Some photoreceptor cells are already paired and show disarrayed microvilli with circularly ordered filaments inside. In ocelli of 2-day-old pupae, when a retinogenous and a lentinogenous cell layer can be clearly distinguished, cell membranes of the distal part of two photoreceptor cells begin to interdigitate with each other and so start to form the definitive microvilli. At the beginning the microvilli often occupy the whole width of the developing rhabdom (Fig. 1).
