1. Like other arthropods, the vision of the varroa mite is similar to that of the honey bee with regard to the colour spectrum (ultraviolet).
2. The vision of the varroa mite is similar to that of humans with regard to the perception of the colour red.
3. Is completely absent.
4. The achromatopsic vision of the varroa mite allows it to distinguish only between black and white.

Which answer(s) is/are correct?

In spring:

1. The approximately 500 gynes (fertilised queens) that left the secondary nest hidden at the top of a tree and survived the winter build a primary nest to found a new colony.
2. In spring, the gynes (fertilised queens) emerge from their winter shelter to feed on nectar.
3. The founding queens (queens building an embryonic nest) lay diploid eggs from which workers emerge that are approximately the same size as the queens.
4. The gynes (fertilised queens) engage in fierce fighting to usurp embryonic nests.
5. The first workers reared by the founding queens are larger than the workers reared by subsequent generations of workers.
6. The workers of the Asian hornet feed their queen with a royal jelly–like substance reminiscent of that produced by nurse bees of the honey bee.

Water is indispensable for the basic metabolism of each individual in the colony. The “nurse bees” use it to produce royal jelly and brood food; the “climate bees” use it for thermoregulation and for controlling humidity inside the hive …

How much water does a colony need over the course of a year?

1. About 20 litres
2. About 33 litres
3. More than 50 litres

1. Detail of a contemporary abstract sculpture, “Elliptical Sequins,” with acrylic paint applied using a palette knife
2. Detail of the hair of the goddess Artemis, generated by AI
3. Asian hornet nest
4. Other

What is the weight of a wax scale produced by the wax glands of bees?

1. BVT has robust and reproducible clinical efficacy comparable to venom immunotherapy (VIT).
2. BVT is a standardized form of immunotherapy based on validated protocols.
3. The literature on BVT mainly shows limited clinical effects that are strongly influenced by methodological bias.
4. BVT is recommended as a therapeutic alternative for beekeepers allergic to bee venom.

One of your colonies is inactive in mid-February. It had provided you with a good harvest last year. Upon opening the hive, you find that the colony has died; the number of dead bees on the frames and on the hive floor is low, the brood pattern is patchy, and food reserves are still well present.

1. ~+15°C
2. ~+5°C
3.  ~-7°C
