AbstractThe identification of honey bee (Apis mellifera) subspecies is often based on the measurements of workers’ fore-wings. The interpretation of the measurements can be difficult because the phenotype of workers is affected by both genetic and environmental factors. Moreover, it is not clear how the phenotype is affected by maternal inheritance. We have used the methodology of geometric morphometrics to verify if hybrids of honey bee subspecies and their backcrosses are more similar to either the father or mother colony. The comparison was based on fore-wing venation of three honey bee subspecies: A. m. carnica, A. m. caucasica, A. m. mellifera. First generation hybrids and backcrosses of those subspecies were obtained through instrumental insemination. Workers of the hybrids were compared with their parental colonies. The shape of wing venation was more similar to the maternal than to parental colony. This phenomenon was particularly visible in first generation of hybrids but it was also present in backcrosses. There were also symptoms of genetic dominance of some subspecies but this effect interacted with maternal inheritance and was difficult to interpret.

Measuring morphological characteristics of honey bee, <em>Apis mellifera</em>, at different times is important to assess the degree of race purity, to predict colony productivity, and to understand environmental impacts on honey bees. The study aims to characterise current honey bees of Northwest Egypt, namely El-Behera governorate, and to track occurred changes to their morphological characteristics since 2007. Samples of honey bee workers were collected from four districts in El- Behera governorate. Nine body and six wing characteristics were measured. Morphological characteristics of honey bees belonging to these districts were previously measured during 2007. To track changes, a comparison between new (2014) and previous (2007) measurements of morphological characteristics was done. The current bees of El-Behera are slightly larger than those of 2007, emphasising no reduction in colonies productivity. There is evidence that environmental factors have not caused much stress on the colonies since 2007. The results of this study are useful in providing understanding of the current state of bees in Egypt, and the likely improvement of future beekeeping.

There are several morphological differences among the honey bee subspecies, which proofs that they adapted different way to the environmental factors of the given area. Morphological observations are not the only way to separate subspecies, it is possible on their genetic speciality as well. The authors’s aim in this present study was to examine morphological characteristics of subspecies, furthermore looking for correlation between morphological parameters and honey yield. According to their results, among the most important parameters considered by Hungarian breeders, in the case of the native Apismelliferacarnica subspecies, the proboscis length could be the indirect tool for honey-productivity focused selection.
