“…The honey samples tested in this work were proven to be sterile (results not shown) rolling out this hypothesis. It could be stipulated that some portion of honey catalase (the enzyme being present in all living cells) could originate from bees' external parasites such as V. destructor [52,53].…”

Varroa destructor is a parasitic mite responsible for the loss of honey bee (Apis mellifera) colonies. This study aimed to find a promising marker in honey for the bee colony infestation level using fluorescence spectroscopy and biochemical analyses. We examined whether the parameters of the honey samples’ fluorescence spectra and biochemical parameters, both related to proteins and phenolics, may be connected with the level of honey bee colonies’ infestation. The infestation level was highly positively correlated with the catalase activity in honey (r = 0.936). Additionally, the infestation level was positively correlated with the phenolic spectral component (r = 0.656), which was tentatively related to the phenolics in honey. No correlation was found between the diastase activity in honey and the colonies’ infestation level. The results indicate that the catalase activity in honey and the PFC1 spectral component may be reliable markers for the V. destructor infestation level of the colonies. The obtained data may be related to the honey yield obtained from the apiaries.

“…Bovine SOD (ng) (Mason 2016;Dmochowska-Ślęzak et al 2016). As demonstrated in the MCO system, when DPPrx1 was present in higher concentrations, the accumulation of nicked DNA was minimized, supporting that DPPrx1 possesses antioxidant activity (Figure 3.5).…”

“…In other species these compounds have been shown to lead to the formation of the free radicals quinone and aglycone (Mason and Bowers 2017). Free radicals can be extremely harmful to the mountain pine beetle because they deplete fat stores, degrade DNA and protein, and damage gut tissue (Mason 2016;Dmochowska-Ślęzak et al 2016). Therefore, being able to properly metabolize such compounds is important to the mountain pine beetle's survival during host colonization.…”

“…In contrast to the multiple proteins for degrading H2O2, the superoxide anion is only broken down by SOD (Figure 1.1; Figure 1.2). Therefore, SOD is likely critical to successful mitigation of free radicals in the mountain pine beetle (Dmochowska-Ślęzak et al 2016). Figure 1.2 -Key oxidative stress proteins (Superoxide dismutase, Peroxiredoxin, Catalase, and Glutathione peroxidase) used by the mountain pine beetle, their free radical substrates, and primary electron donors, derived from Ajuwon et al (2015).…”

Understanding the mountain pine beetle detoxification systems is vital for predicting its continued spread into the novel jack pine host. Phylogenetic analyses were conducted for mountain pine beetle catalase, glutathione peroxidase, superoxide dismutase, and peroxiredoxin. These proteins were generally conserved, but there were differences in some key functional motifs. Specifically, a peroxiredoxin (DPPrx1) contained a unique combination of hyperoxidation motifs. DPPrx1 and a superoxide dismutase (DPSOD1) were selected for further functional analyses and demonstrated higher reactivity when compared to other SOD and Prx proteins. Also, DPPrx1 experiences hyperoxidation at a lower H2O2 concentration (~0.06 mM) than human peroxiredoxin (~0.12 mM). In other systems, hyperoxidized peroxiredoxin does act as a signal molecule for the expression of other oxidative stress proteins. Therefore, due to its relatively high reactivity and potential role as a cellular signal, DPPrx1 could serve as a future pest management target.
