Figure 1. Examining 3D flight performance in honey bees and Asian hornets. (a) Conceptualization of the experimental setup with a stereovision camera fixed over a hive flight board, registering all activity in the volume of air in front of the hive on a computer, which analyses the trajectories of Asian hornets (blue) and honey bees (green). (b) Daily time series of the total number of honey bees (green) and hornets (blue) (trajectories). Lines represent model predictions and shaded areas show the 95% confidence intervals.
Figure 2. Daily time series of (a) the flight speed, (b) curvature and (c) time spent hovering by honey bees entering (in red) or leaving (in grey) their hive and Asian hornets (in blue). Differences in letters denote significant difference using Kruskall-wallis tests. Lines represent model predictions and shaded areas show the 95% confidence intervals. Dot lines show non-significant trends.
Figure 3. Flight performance in (a) speed, (b) curvature and (c) time spend hovering of the Asian Hornet in blue, honey bees entering the hive in red or leaving it in grey. Time spent hovering is based on the threshold 2 indicator (see methods).
Figure 4. Predation success of the Asian hornets modelled as a quadratic function of hornet numbers. Line represents the model prediction and the shaded area shows the 95% confidence intervals.
Figure 5. Hornet density (Log10 trajectories) effects on (a) speed of bees entering the hive, (b) speed of bees leaving the hive, (c) curvature of bees entering the hive trajectories. Lines represent model predictions and shaded areas show the 95% confidence intervals.
Figure 6. Hornet density (Log10 trajectories) effects on the coefficient of variation (CV) of (a) speed, (b) trajectory curvature and (c) hovering percentage in hornets. Lines represent model predictions and shaded areas show the 95% confidence intervals.
