What do female Varroa mites do after entering a larval cell?

The appropriate action of female Varroa mites after entering a larval cell is to lay eggs. Once inside the cell, the mite typically attaches to a developing bee larva and begins to feed on its bodily fluids. This feeding behavior is crucial for the mite's life cycle and reproductive success. As they feed, they also lay their eggs within the cell. The mites' offspring develop alongside the bee larva, leading to further infestation once the new bee emerges.

In terms of the incorrect choices, requesting nectar does not align with the behavior of Varroa mites, as they do not consume nectar. Hiding in food is not a relevant strategy for mites, as they have a specific parasitic relationship with bee larvae. Repelling other bees also would not be applicable, as Varroa mites do not possess such mechanisms and instead focus on surviving and reproducing within the hive. The correct answer highlights the biological and ecological role of Varroa mites in the life cycle of honeybees and underscores the challenges they pose to bee populations.
