difference between apis cerana and mellifera

After depositing a tracheal mite, we observed the bee’s responses for 7 min, within which autogrooming responses to mites were sufficiently observed and mites did not enter spiracles, based on preliminary observations (Danka and Villa 2003). Circles give the median apparent spatial frequency and lateral position, whiskers represent the second and third quartiles. In a similar paradigm, B. terrestris was found to have a contrast sensitivity of 1.57 (64% contrast; Chakravarthi et al., 2016), which is much lower than that measured for flight control in the same species (Chakravarthi et al., 2017), but experimental conditions may have contributed to this low value (Chakravarthi et al., 2016). 2016), the frequency of GR was higher in A. mellifera than A. cerana without tracheal mites. Apis cerana can tolerate varroa and has developed an effective defence strategy against the Giant Hornet, against which mellifera bees have no defence. The varroa mite does not cause significant problems in the original host A. cerana, but it can infest the new host A. mellifera at higher density and has become a global pandemic. Overall, these results indicate that, for directed forward flight, A. mellifera has a higher spatial resolution threshold (between 0.11 and 0.18 cycles deg−1 apparent spatial frequency) than A. cerana (between 0.08 and 0.12 cycles deg−1 apparent spatial frequency).

Our results show that the system mediating flight control in A. cerana and A. mellifera has a low resolution when compared with the anatomical estimate and is also potentially lower than the system mediating object detection, but that it is sensitive to very low contrasts.

Obtaining reliable visual information is particularly important for flight, where visual control of speed and position is essential for avoiding collisions with obstacles. Some researchers have proposed that the infestation rate decreases if honey bees sufficiently remove the tracheal mite before it migrates into a new host and that autogrooming is involved in mite removal (Danka and Villa 2003; Sakamoto et al. Representative flight trajectories are shown in Fig. Such allogrooming normally involves a dancing bee and a bee that responds to the dance by grooming the dancer (Milum 1955).
