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.
