Multiple choice zoology insects and human welfare bee keeping apiculture apiculture, sericulture and fisheries

In honey bee, drones are produced by

  1. Unfertilized eggs

  2. Fertilized eggs

  3. Low fed larvae

  4. Larva fed with royal jelly
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Drones are male honey bees which are the product of an unfertilized egg. Drones do not have stingers and do not participate in nectar and pollen gathering. A drone's primary role is to mate with a fertile queen. 

Therefore, the correct answer is option A.

Honey is collected by ................

  1. Wasp

  2. Housefly

  3. Butterfly

  4. Bees
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bees visit flowers to collect nectar. With its long tongue, a honeybee extracts the nectar and stores it within its body until it returns to the hive. While inside the bee's body, the nectar combines with special enzymes that change its chemical properties so it becomes ready for extended storage. The honeybee regurgitates the nectar after returning to the hive, and another worker bee will deposit the nectar into a honeycomb. To change the nectar into honey, worker bees hasten the evaporation process by using their wings to fan air around the honeycomb. After the removal of nearly all of the water from the nectar, it becomes honey. At this point, the honeybees secrete a liquid over the honeycomb to seal it. This liquid hardens and becomes beeswax, which keeps moisture and air from reaching the honey.

Which set is of beneficial insects to man?

  1. Honey bee, lac insect, cochineal insect

  2. Silk worm, honey bee, wasp

  3. Honey bee, silk worm, cockroach

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Although most of the insects are not useful to us and mainly acts as a vector for many diseases like cockroach, houseflies, mosquitoes etc. There are some insects which are beneficial to man as well like honeybees which produces honey, wax etc. Lac insect (kerria lacca) is another helpful insects produces lac which is a natural protein fibre used in textile industry and cochineal insect is another helpful insect which produces red food dye. 

Therefore, the correct answer is option A

Queen bee is adapted for ...........

  1. Laying eggs

  2. Laying eggs and rearing the young.

  3. Preparing honey

  4. Controlling other bees
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The queen bee is the most valued bee in the whole hive. A queen bee can live for 3-5 years. The main job of queen is to lay eggs. The queen mates only once with several male (drone) bees, and will remain fertile for life. She lays up to 2000 eggs per day. Hence, option A is correct.

Honey bee is regarded as a social insect, because

  1. Bees interact within each other

  2. Makes honey for humans to eat

  3. They have poisnous sting

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • The honey bee represents only a small percent of the whole bee species ever through it is one of the most popular bees.
It is the only surviving group of bees from Apini tribe, which comes under Apis genue.
  • They are known for producing and storing, or liquified sugar, as well as  building impressively long needs using,  was secreted by workers in a particular colony.
  • They are called a social insect becomes it lives in a colony or community with other individuals of the same species.
  • Honey bees measure about $15\ mm$ light and are light brown in colour. Their body is segmented: stinger, legs, antenna, their segments of thorax and six visible segments of abdomen.
  • In honey bees, the drones (males) are entirely derived from the given, this mother. The diploid given has $32$ chromosomes and diploid drones $16$ chromosomes.
  • Workes lay an unfertilised egg. Batches of works bees are short-lived and are constantly being replaced by the next batch, so this kin selection is possible a strategy to ensure the proper working of hive.

Which of these protect the hive, collect nectar and pollen and look after the eggs?

  1. Queen bee

  2. Worker bee

  3. Drone

  4. Male bee
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The worker bees are the smaller, sterile female bees. They are called as nurse or housekeepers. They are involved in taking care of the hives and the young ones. They help in building the hives and protect the hives from the other animals. They help in pollination, collect the nectar and transfer the pollens between the flowers. 

Thus, the correct answer is option B.

In which of the following bee, wax glands are found?

  1. Queen bee

  2. Drone

  3. Workers

  4. Both A and C
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Worker bees, which live only around 35 days in summer, make wax from about the 10th day of their lives to the 16th. When workers are roughly 10 days old, they develop special wax-producing glands in their abdomens. The glands convert the sugar in the honey into wax, which seeps through small pores in the bee’s body leaving tiny white flakes on its abdomen. These bits of wax are then chewed by the bees. The chewed wax is added to the construction of the honeycomb. Hence, option C is correct.

The honey bees exhibit a type of dance to communicate the location of food. What is this known as?

  1. Waggle dance

  2. Tap dance

  3. Round dance and waggle dance

  4. Break dance
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The honey bees exhibit 2 types of dance to communicate the location of food, the round dance and the tail-wagging or waggle dance.

The round dance is used for food sources 25-100 meters away from the hive or closer. After distributing some of her new-found nectar to waiting bees the scout will begin running in a small circle, switching direction every so often. The round dance does not give directional information. Bees elicited into foraging after a round dance fly out of the hive in all directions searching for the food source they know must be there.
As the food source becomes more distant the round dance is replaced by the waggle dance. The waggle dance includes information about the direction and energy required to fly to the goal.  
Therefore, the correct answer is option C.

Which of the following is a correct statement?

  1. Drone is diploid.

  2. Apis indica is largest wild bee.

  3. Wax is excretory product of bee.

  4. Frisch discovered communication in bees.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

1st statement is incorrect, as drones of the honey bee are haploid and not diplod. They develop parthenogenetically from unfertilized eggs. 

2nd statement is incorrect, as Apis dorsata laboriosa and not Apis indica, the Himalayan honey bee, is the world's largest honey bee.
3rd statement is incorrect, as bee's wax is not a waste material, it is secreted by special wax glands present in the abdomen. It is used for making the hives of honeybee.

4th statement is correct, as Karl Von Frisch discovered the communication and transmission methods in the honey bee during a number of experiments and found out that when a foraging bee returns to the hive, it performs a 'waggle dance'. 
Hence, option D is correct.

Waggle dance in Honey Bee represents

  1. Distance of food source

  2. Direction of food source

  3. Both distance and direction of food source

  4. Distance and direction of enemy
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The waggle dance is a special 'figure of eight' dance that is done by the honey bee in its hive. By this, a worker tells the others where it has found nectar. It is done to give other bees information about the direction and distance to flowers that have nectar or pollen or both.

Given below are the characteristics of ''X''. Which of the following is ''X''?
i.   Build the hive
ii.  Collect nectar and pollen
iii. Clean the cells and protect the hive

  1. Queen bee

  2. Worker bee

  3. Drone

  4. Male bee
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
The worker bees are called as nurse or housekeepers. They help in building the hives and protect it from predatory animals. The function of worker bees is to take care of the hives and the young bees. They help in pollination as while collecting the nectar they transfer pollen between flowers. Thus the correct answer is option B.
