  2. 10. Adult varroa mites piggy back rides on adult bees and as a consequence may be spread from one colony to __________, in that bees often drift from colony to colony.

  3. 2. Unlike the tracheal mite the varroa mites can be seen with the unaided

  4. 11. Only adult ________ (give the sex) varroa mites are found on adult bees.

  5. 3. Like the tracheal mites, varroa mites obtain their nutrient requirements by feeding on the bee's ________(pick 2)__.

  7. 4. Once the varrroa mite enters the uncapped cell it hides beneath the __________ to avoid detection by adult bees, who otherwise would likely remove it.

  8. 13. The bee larva that the mite is hiding beneath is still being fed a liquid diet by nurse bees, the mite would normally drown in this liquid, HOWEVER the mite turns itself upside down beneath the larva and extends two breathing tubes above the liquid, the tubes are called_______

  9. 5. Once the cell of the prepupa is capped, the mite faces a second danger that of being entangled in the cocoon's silk, spun by the developing bee, to avoid the possibility of becoming entangled in the silk the mite leaves her hiding place and attaches herself to the developing______.

  10. 14. Once the cocoon is completed, the mite starts to fed by piercing a hole between the forming legs of the bee, now in its_______stage.
