One Liner Objectives About Sericulture & Apiculture
1. The combs are built with bee wax which is secreted by Four pairs of wax glands located in 3-6 abdominal sterna.
2. Royal jelly is produced by hypopharyngeal salivary glands of the workers honey bees.
3. Royal jelly is also called as brood food or bee milk.
4. In honey bees, the queen substance is secreted by mandibular glands.
5. Honey stomach is also called as proventriculus.
6. Swarming is the method of reproduction in which a part of colony migrates to a new site to make a new colony.
7. Fertilized eggs give birth to Queen and Workers whereas unfertilized eggs give birth to Drones.
8. Round dance is used to indicate short distance.
9. Tail wagging dance is used to indicate a longer distance.
10. The duration when there is no honey flow is called Dearth period.
11. The complete desertation of the bee hive by the honey bees is called Absconding.
12. The replacement of the old queen by the new daughter queen is known as supersedure.
13. The infestation of a mite in honey bee is known to cause a disease called Acarine disease.
14. The species of honeybees that not fully domesticated Rock bees & little bees.
15. The species of honeybees that are fully domesticated Indian bees & Italian bees.
16. The first abdominal segment when fused with the meta thorax in bees is called as propodeum.
17. The part of hive rearing which allows workers to pass through it easily but retains the queen in brood chamber is Queen excluder.
18.Pollen basket is present in tibia part of hind leg.
19. Pollen basket or corbicula is primarily meant for storing the pollen grains.
20. The antennal cleaner is present in fore leg.
21. Bee venom is secreted from Acid gland by honeybees.
22. The larval duration of worker, drone and queen is 4,7 & 5 days respectively
23. When the larvae is allowed to feed its entire larval period on royal jelly it develops into Queen.
24. Foraging refers to the filed visits of the honeybees for collection of nectar, pollen, propolis and water.
