Directional and fluctuating asymmetry were estimated in worker bees fed on sugar syrups in comparison with feeding with honey (control). By using 25 traits of wing venation pattern on left and right forewing of worker honey bees, it could be stated that directional asymmetry (DA) was not related to the type of feeding. Fluctuating asymmetry (FA), however, differed between characters and between feeding treatments, but no interaction was found between them. The individual characters were combined and analyzed as composite fluctuating asymmetry to maximize the probability of detecting (FA)-stress relationship when it exists. The result showed that (FA) of distances between vein junctions were significantly higher in sugar-feeding than in honey-feeding colonies.

Wing asymmetry was used to measure the possible stress which could be created when we feed honeybee colony with cane and beet sugar syrup in comparison with feeding with honey (control). For this purpose, 25 traits of wing venation pattern on left and right forewing of drone honey bees were used. The results indicated that directional asymmetry (DA) was not related to the type of feeding. Fluctuating asymmetry (FA) differed between characters and between feeding treatments, but no interaction was found between them. The individual characters were combined and analyzed as composite fluctuating asymmetry (CFA) to maximize the probability of detecting (FA)-stress relationship when it exists. The result showed that (CFA) of vein angels were significantly higher in sugar-feeding than in honey-feeding colonies.
