“…A comparison of parameters describing O. bicornis and A. mellifera validates the above conclusion (Lipiński and Żółtowska 2005;Saltykova et al 2007;Lipiński et al 2008;Farjan et al 2012).…”

“…The reverse was observed in O. bicornis , where SOD activity was 2.5-fold higher in active bees than in feeding larvae. In solitary bees, peroxidase activity was more than 40-fold higher than in honeybee communities (Lipiński and Żółtowska 2005;Saltykova et al 2007;Lipiński et al 2008;Farjan et al 2012), which could be attributed to the different tasks and roles played by females in both species. Honeybee workers remain in the hive for three weeks, where they perform various tasks.…”

“…Free radicals are also generated in response to biotic and abiotic factors, including pathogens, UV radiation, ultrasound waves, and toxic substances in the environment and the diet (Bartosz 2003;Lipiński and Żółtowska 2005). The increased use of agricultural chemicals and growing environmental pollution pose the greatest threats to the survival of bees.…”

-An efficient antioxidant system is of particular importance for insects whose high metabolic rates promote increased formation of reactive oxygen species (ROS). The amount of ROS can be additionally increased by environmental factors. This study investigates the ability of red mason bees (Osmia bicornis L.) to inactivate free radicals during insect development. Both male and female bees were studied, from the larval to the active imago stage. The activity of four antioxidant enzymes, superoxide dismutase, catalase, peroxidase and glutathione Stransferase, was measured; and glutathione content and total antioxidant status were determined. The highest values of the examined parameters were found in feeding stages-in larvae and in active imagines of both genders. Significant differences between genders were noted mainly in catalase activity, which was lower in overwintering imagines and active females than in males. Most differences were observed between females and males after emergence.antioxidants / pollinating insects / insect metabolism / development / enzymes

“…(), the red mason bee, as a solitary insect species, should have more effective antioxidant barriers than the honey bee, which is a social insect. This hypothesis is also confirmed by the results reported previously for O. bicornis (Dmochowska et al ., ; Dmochowska‐Ślęzak et al ., ) and previous findings in studies of A. mellifera (Lipiński & Żółtowska, ; Saltykova et al ., ; Lipiński et al ., ; Farjan et al ., ; Korayem et al ., ). A comparison of the present results with the previous data demonstrates that the antioxidant parameters are higher in the red mason bee than in A. mellifera .…”

The red mason bee Osmia bicornis L. (Hymenoptera: Megachilidae) belongs to a group of insects that undergo an obligatory diapause in the imago stage. Red mason bees (O. bicornis) consume oxygen during overwintering diapause, and reactive oxygen species can be produced despite substantial inhibition of metabolism. These are first studies to investigate the antioxidant system in diapausing red mason bees and to compare the antioxidant systems of overwintering and active imagines. The present study analyzes total antioxidant status, glutathione and ascorbic acid levels, and the activity of superoxide dismutase, catalase and peroxidase in overwintering (October to March) and active (April) female and male O. bicornis. Diapause phases (prediapause, diapause and post‐diapause) cannot be distinguished based on the parameters of the antioxidant system of the bees. During overwintering, a significant decrease is noted only in ascorbic acid content. The remaining antioxidants remain fairly stable, which indicates the absence of oxidative stress in diapausing specimens. The analyzed parameters distinguish diapausing bees from active insects. Excluding total antioxidant status, the evaluated parameters are significantly higher in active individuals than in overwintering specimens. Sex‐related differences are found only for catalase, the level of which is consistently higher in males than in females.

“…This mite acts directly by consuming the brood/adult bee hemolymph, and indirectly by vectoring viruses and causing immunosuppression in bees (Wilfert et al, 2016). Antioxidants play a significant role in parasitehost interactions (Sorci & Faivre, 2009;Lipiński & Żółtowska, 2005). Therefore, the aim of this study was to investigate the poorly known antioxidant defense system of V. destructor (parasite) for further comparison with the better described (by other authors) antioxidant potential of A. mellifera (host).…”

A b s t r a c t Varroa destructor is a parasitic mite of the Western honey bee. The activity of five antioxidant enzymes of V. destructor were analysed. Glutathione content and total antioxidant status was also evaluated. Our results suggest that antioxidant enzymes constitute the main line of defense against ROS in V. destructor, whereas low-molecular-weight antioxidants play a limited role in the antioxidant system of mites.
