Preliminary data collected from Vermont apiaries in 2015 National Honey Bee Survey
Figure 1: Results of Vermont apiaries sampled in 2015 National Honey Bee Survey. Mean viral load (virus genome copes/bee) by apiary type (migratory or stationary). Bars represent mean standard error. Deformed wing virus (DWV) load was significantly higher in migratory than in stationary apiaries (p = 0.04). Although not statistically significant, viral loads for chronic bee paralysis virus (CBPV) and Lake Sinai virus (LSV2) were also higher for migratory apiaries. Israeli acute paralysis virus (IAPV) was detected in one stationary and one migratory apiary. Asterisk represents statistical significance at the 0.05 level.
Figure 2: Results of Vermont apiaries sampled in 2015 National Honey Bee Survey. Mite loads (mites/100 bees) by apiary type. Migratory apiaries had significantly higher mite loads than stationary apiaries (p = 0.004). Red line signifies the mite load threshold (3 mites/100 bees) at which colonies experience detrimental effects. Migratory apiaries fell above the threshold value while stationary apiaries fell below the threshold. Asterisks represent statistical significance at the 0.01 level. Bars represent mean standard error.
