“…Twelve of them found a significantly higher prevalence in migratory colonies in some of the pathogens or parasites studied ( Table 1 ). On the other hand, five of them found that migratory colonies showed a significant decrease in pathogen prevalence of DWV ( Jara et al, 2021 ; Simone-Finstrom et al, 2022 ), varroa mites ( Traynor et al, 2016a ; Alger et al, 2018 ) or CBPV ( Pfeiffer and Crowder, 2022 ).…”

“…With regard to honey bee viruses, stationary hives showed in general lower prevalences ( Table 1 ). BQCV was found more prevalent in migratory colonies in the USA (Welch et al, 2009; Alger et al, 2018 ; Pfeiffer and Crowder, 2022 ) and Turkey (Tozcar et al, 2015). However, some of these differences were transient as BQCV prevalence were equal in migratory and stationary colonies after one month in some cases ( Alger et al, 2018 ).…”

“…However, some of these differences were transient as BQCV prevalence were equal in migratory and stationary colonies after one month in some cases ( Alger et al, 2018 ). ABPV had higher prevalence in migratory colonies (Tozcar et al, 2015) while DWV prevalence has been found to be higher in stationary colonies ( Jara et al, 2021 ; Simone-Finstrom et al, 2022 ) or did not show any significant trend (Welch et al, 2009; Bromenshenk et al, 2010; Tozcar et al, 2015; Alger et al, 2018 ; Bartlett et al, 2021 , Pfeiffer and Crowder, 2022 ). Multiple viral infections are not uncommon in honey bees ( Chen et al, 2006 ), but seem to increase in migratory beekeeping operations, where triple infections were found at a higher prevalence (Welch et al, 2009).…”

“…Second, knowledge of colony density in an area of concern is important for the success of a biosecurity response. Pathogens or pests can spread quickly in areas with high colony densities colonies (Seeley and Smith 2015, Dynes et al 2019, Pfeiffer and Crowder 2022). The chances of biosecurity responses succeeding in such cases are low.…”

The demand for honey and pollination services has continued to grow in many countries worldwide, including New Zealand. This has influenced changes in the demographics of the managed population of honey bees (Apis mellifera). We examined historical data to describe how the apicultural demographics in New Zealand have changed temporally and geographically in the four decades to 2020. We also describe trends in honey production and the economic value of pure honey exported from New Zealand between 2000 and 2020. Our findings suggest that commercial apiculture has been key to the intensification of beekeeping in New Zealand during the study period. This is supported by evidence showing pronounced expansion of beekeeping operations among those with more than 1,000 colonies. The intensification has resulted in the density of apiaries increasing threefold across New Zealand during the four decades. While higher numbers of colonies per area produced higher volumes of honey, there was no corresponding improvement in production efficiency. Honey yields per apiary or colony, as indicators of production efficiency, appear to decline from the mid-2000s. The volume of pure honey export increased over 40-fold, a magnitude approximately ten times higher than that of production increase. This reflects a substantial increase in returns from honey exports, mostly driven by the price of mānuka honey. Our findings add to a pool of information to support evidence-based decision making to enhance honey bee health and develop the apicultural industry in New Zealand.

“…1 ). CBPV has clear, overt effects on neural functioning and is a potential emerging threat in Europe and North America ( Budge et al, 2020 ; Pfeiffer and Crowder, 2022 ; Ribière et al, 2010 ; Traynor et al, 2016 ), while DWV is the most prevalent honey bee virus and causes largely covert or sublethal effects from adult infection ( Martin and Brettell, 2019 ; Traynor et al, 2016 ). We hypothesized that infection by either virus would result in decreased diet consumption but also an increased preference for protein-enriched diet relative to uninjected controls, but that the extent of this preference would differ among bee stocks.…”

Viral species differentially influence macronutrient preferences based on honey bee genotype

et al. 2022

Food quantity and macronutrients contribute to honey bee health and colony survival by mediating immune responses. We determined if this held true for bees injected with Chronic bee paralysis virus (CBPV) and Deformed wing virus (DWV), two common honey bee ssRNA viruses. Pollen-substitute diet and syrup consumption rates and macronutrient preferences of two Varroa-resistant stocks (Pol-Line and Russian bees) were compared to Varroa-susceptible Italian bees. Bee stocks varied in consumption, where Italian bees consumed more than Pol-Line and Russian bees. However, the protein: lipid (P:L) ratios of diet consumed by the Italian and Russian bees was greater than that of the Pol-Line bees. Treatment had different effects on consumption based on the virus injected. CBPV was positively correlated with syrup consumption, while DWV was not correlated with consumption. P:L ratios of consumed diet were significantly impacted by the interaction of bee stock and treatment, with the trends differing between CBPV and DWV. Variation in macronutrient preferences based on viral species may indicate differences in energetic costs associated with immune responses to infections impacting different systems. Further, virus species interacted with bee genotype, indicating different mechanisms of viral resistance or tolerance among honey bee genotypes.
