3.6.2.3. Orientation inside the sealed cell

Careful observations of the behaviour of the mite inside the brood cell carried out by Donzé and Guérin (1994) revealed a well-structured spatial and time allocation of its activity. The chemicals involved in this crucial stage of the mite’s life cycle were studied mostly using bioassays based on observation arenas (Donzé et al., 1998; Calderone and Lin, 2001).
