Select the correct statements regarding honeybees.
(i) The queen bee and the worker bees develop from fertilised eggs and are sexually females.
(ii) Males (drones) develop parthenogenetically. from unfertilised eggs.
(iii) Queen bee feeds upon royal jelly and the worker bees feed upon bee bread.

  1. (i) and (ii)

  2. (ii) and (iii)

  3. (i) and (iii)

  4. (i), (ii) and (iii)


Correct Option: D
Explanation:

The female queen bee produces new offspring by laying eggs that have been fertilized by sperm from male drones. These drones are raised in cells that are significantly larger than the cells used for workersA type of asexual reproduction in which egg develops without fertilization to form a new individual. If parthenogenesis (type of asexual reproduction in which egg develops without fertilization to form a new individual) takes place in bees, a drone or male bee is produced. Royal jelly is a honey bee secretion that is used in the nutrition of larvae, as well as adult queens. It is secreted from the glands in the hypo-pharynx of nurse bees while the worker bees are fed the bee bread. As a result of the difference in diet, the queen will develop into a sexually mature female, unlike the worker beesQueens are raised in specially constructed queen cells.

So, the correct option is '(i), (ii) and (iii)'.

In which of the following, parthenogenesis is observed?

  1. Honey bee

  2. Silkworm

  3. Earthworm

  4. House fly


Correct Option: A
Explanation:

Parthenogenesis is a natural form of asexual reproduction found most commonly in lower organisms and plants. It is shown by honeybee, where male honeybees (drones) are produced parthenogenetically from unfertilized eggs. The only function of drones is to fertilize the queen bee. Hence, option A is correct.

If a honey bee is conveying an information, by round dance then the distance of source will be about 

  1. 1000 mtrs

  2. 50 mtrs

  3. 2000 mtrs

  4. 150 mtrs


Correct Option: B
Explanation:

The round dance is performed by the worker bees when the food source is within a 50 metres of the hive. The bee runs one way in the circle, stops and then runs the other way. During the dance the worker bee passes a sample of the nectar to the other workers so they know the taste and smell of the source.

Therefore, the correct answer is option B.

In honey bee, drones are produced by

  1. Unfertilized eggs

  2. Fertilized eggs

  3. Low fed larvae

  4. Larva fed with royal jelly


Correct Option: A
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


Correct Option: D
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.

Explanation:

The queen bee is the most valued bee in the whole hive. The main job of queen is to lay eggs.  She can lay up to 2,000 per day. Hence, option C is correct.

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

  1. Queen bee

  2. Drone

  3. Workers

  4. Both A and C


Correct Option: C
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.

Number of queens in a hive is ...................

  1. 10

  2. 15

  3. 20

  4. 1


Correct Option: D
Explanation:

Commonly one queen is found to be present in each hive and feeds on royal jelly. She is the queen in real sense as the mother of the colony.

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


Correct Option: C
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.

Life span of worker bee is ................

  1. 10 days

  2. 15 days

  3. 6 weeks

  4. 10 weeks


Correct Option: C
Explanation:

Workers bee are the smallest castes. The life span of an adult worker bee varies with the time of the year. It takes about twenty one days in their development from egg to adult and when the colony is active in spring and summer, worker bee may live as long as 5-6 weeks. During the inactive period in winter a worker bee lives five months or more. Hence, option C is correct answer.

An animal where male carries half the chromosomes present in female is?

  1. Amoeba

  2. Gorilla

  3. Honey Bee

  4. Geometrid Moth


Correct Option: C
Explanation:

Bees have a different number of chromosomes. Females, workers and queens have 32, 16 are contributed by the queen's eggs and 16 come from the drones sperm. Since drones hatch from unfertilized eggs, they only have the 16 chromosomes that were in the egg. Drones are haploid because they only have one set of chromosomes.


So, the correct answer is 'Honey Bee'.

What is true in case of Honey Bee?

  1. Male diploid, female haploid

  2. Male diploid, female diploid

  3. Male haploid, female haploid

  4. Male haploid, female diploid


Correct Option: D
Explanation:
In case of honey Bees, males develop from unfertilized eggs and are haploid, and females develop from fertilized eggs and are diploid (Haplodiploidy).

So, the correct answer is 'Male haploid, female diploid'.

Male produce sperms by mitosis in _______________.

  1. Periplaneta americana

  2. Apis mellifera

  3. Drosophila melanogaster

  4. Lepisma


Correct Option: B
Explanation:
In organisms which have haploid males (such as honeybees, Apis mellifera), there is a variation of meiosis during spermatogenesis. The meiosis-I is abortive i.e. the chromosomal events such as crossover and separation of homologous chromosomes, do not happen. However, some cytological changes do happen which is described by Sharma et al (1961) as "simulation of the normal meiosis I". This is followed by meiosis II (which is mechanistically same as mitosis). So, basically there is no halving of the number of chromosomes and the gametes are also haploid.

So, the correct answer is 'Apis mellifera'.

Which one shows arrhenotoky in development?

  1. Pumea

  2. Drosophila

  3. Apis

  4. Bonellia


Correct Option: C
Explanation:
In most honey bees, unfertilized eggs develop into haploid males via arrhenotokous parthenogenesis. The Cape honey bee (Apis mellifera capensis) is different. Although mated queens always produce females sexually, if workers lay unfertilized eggs the eggs develop into diploid females via thelytokous parthenogenesis.

So, the correct answer is 'Apis'.

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


Correct Option: B
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. 

Which among the following is secondary product of honey bee?

  1. Bee wax

  2. Propolis

  3. Honey

  4. Pollen


Correct Option: A
Explanation:

The best known primary products of beekeeping are honey and wax, but pollen, propolis, royal jelly, venom, queens, bees and their larvae are also marketable primary bee products. Most of these products can be consumed as they are produced by the bees. There are additional uses where bee products are an ingredient of another product. 

So the correct answer should be 'option B and D".

If the food source is in the opposite direction of sun and distance from the hive is 85 meters, then scout worker bee will convey this information by

  1. Round dance

  2. Straight dance

  3. Tail wagging dance - upward

  4. Tail wagging dance - downward


Correct Option: D
Explanation:

A scout worker honey bee performs a waggle dance to convey the information to the rest of the hive about the food source. The direction the bee moves in relation to the hive. This indicates the direction of food with respect to direction of sun. If it moves vertically and upward, the source is directly towards the Sun. If it moves vertically and downward, the source of food is in opposite direction of sun. The duration of the tail wagging dance signifies the distance.

Thus, the correct answer is 'Tail wagging dance - downward.'

In bees, pollen basket is present in

  1. Prothoracic legs

  2. Mesothoracic legs

  3. Metathoracic legs

  4. Both meso and metathoracic legs


Correct Option: C
Explanation:
The pollen basket is an arrangement of hairs found on the tibia of the metathoracic legs of some bees. The bees collect pollen and, having moistened it with saliva using their tongues, they transfer it to their hind legs and pack it into the pollen basket. By packing pollen in this manner they compact it so that it can be easily carried back to the hive or nest.
So, the correct answer is 'Metathoracic legs'.

The wax glands in honey bee are present ..............

  1. On the ventral side of the last segment.

  2. On the ventral side of last four abdominal segments.

  3. On the dorso-lateral side of first two abdominal segments.

  4. On the lateral side of last two abdominal segments.


Correct Option: B
Explanation:

Four sets of wax glands, situated inside the last four ventral segments of the abdomen, produce wax for comb construction. Wax bees build cells from wax, repair old cells, and store nectar and pollen brought in by other workers. Early in the worker bee's career, she will exude wax from the space between several of her abdominal segments. 

The name 'honey stomach' in bees is applied for

  1. Gizzard

  2. Pharynx

  3. Stomach

  4. Crop


Correct Option: D
Explanation:

The crop also called as honey stomach or honey sack is a specialized part of foregut. It is similar to distensible sack. The main function of the crop is transport and storage of liquid food (water, nectar and honeydew). Another function of crop is uptake of water from its lumen. 

Therefore, the correct answer is option D.

Which of the following statement about bee colony is wrong?

  1. Domesticated species are A.indica and A.mellifera.

  2. Sex differentiation is due to haplodiploidy.

  3. They are female dominant societies.

  4. Fertilized eggs develop into sterile females only.


Correct Option: D
Explanation:

Honey bee queen control the sex of their offspring as eggs pass through the ovary into the oviduct, a queen can determine whether a particular egg is fertilized or not. Unfertilized eggs become drone honey bees, while fertilized eggs develop into female workers and queens. Female workers do not mate, but they can lay infertile eggs, which in turn become male honey bees.

What is the waxy substance produced by honey bee to repair combs called as?

  1. Propolis

  2. Honey dew

  3. Nectar

  4. Sporopollenin


Correct Option: A
Explanation:

Propolis or bee glue is a resinous mixture that honey bees collect from tree buds, sap flows, or other botanical sources. It is used for sealing unwanted open spaces in the hive. Propolis is used for small gaps while larger spaces are usually filled with beeswax. Propolis is sticky at and above room temperature, 20$^o$C (68$^o$F). At lower temperatures, it becomes hard and very brittle.

So, the correct answer is 'Propolis'

In which part of the body, honey bee keep the nectar for sometime? 

  1. Crop

  2. Mouth

  3. Gizzard

  4. Pollen basket


Correct Option: A
Explanation:

Honey is made using the nectar of flowering plants and is saved inside the beehive for eating during times of scarcity. Nectar is extracted from flowers using a bee's long, tube-shaped tongue and stored in its extra stomach, or crop. While in the crop, the nectar mixes with enzymes that transform its chemical composition and pH, making it more suitable for long-term storage.

Honey bee after discovering the new source of nector / honey can convey the direction

  1. Cannot convey the direction.

  2. By round or tail wagging dance.

  3. By round dance only.

  4. By tail wagging dance only.


Correct Option: B
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.  Hence option B is correct.

Worker bees are .............

  1. Fertile males

  2. Fertile females

  3. Sterile females

  4. Sterile males


Correct Option: C
Explanation:

A worker bee is any female bee that lacks the full reproductive capacity of the colony's queen bee. They are smaller, their abdomens are shorter, and on their hind legs they possess pollen baskets, which are used to carry pollen back from the field. The life span of worker bee is six weeks during the colony's active season. However, worker bees live longer (four to eight months) during the less active winter months.

If the source is opposite to the direction of sun and distance is more than 75 meters then honey bee will convey the direction by

  1. Clockwise round dance

  2. Upright down tail waving dance

  3. Anti-clockwise round dance

  4. Opposite to 2 o'clock dance


Correct Option: B
Explanation:

If the new source of food is farther from the hive than 75-100 meters, the returned scout performs a dance which follows a figure-eight course while the abdomen is being wagged or laterally vibrated (upright down tail waving dance). The dancer's speed is a function of the nearness of the supply. In a quarter minute she executes 9 to 10 full figures if she has flown in from only 100 meters. 

Therefore, the correct answer is option B.

Main sugar present in the honey is  

  1. maltose

  2. levulose

  3. dextrose

  4. ribose.


Correct Option: B
Explanation:

Levulose is a simple sugarfound in honey and in many ripe fruits. Its a sirupy variety of sugar, rarely obtained in crystallized form present widely in honey.

In honey the percentage of maltose and other sugar is

  1. 9.2

  2. 8.81

  3. 10.5

  4. 11.2


Correct Option: B
Explanation:

Honey is mainly consists of fructose (about 38-55%) and glucose (about 31%), with remaining sugars including maltose, sucrose and other complex carbohydrates. Maltose, sucrose and other sugars accounts for 8.81%.

The contrast in the development and social behavior of the western honey bee, Apis mellifera, has been shown to depend on whether bee larvae are fed royal jelly or not.
Those larvae fed jelly will accelerate growth and become queens; all others are destined to become drones. The drastically different developmental outcomes occur despite equivalent genomes, suggesting an epigenetic mechanism.

Which of the following choices would be a feasible mechanism to investigate?

  1. Recombination of genomic DNA leading to the loss and expression of relevant genes.

  2. Post-translation modification leading to altered function of the proteins involved in development.

  3. Methylation of histone proteins or genomic DNA resulting in the silencing of genes.

  4. Examining the jelly for genetic material that when incorporated into the larvae, promote the royal pathway.


Correct Option: A
Explanation:

A- Recombinant DNA technology is utilized to alter a known DNA sequence from one organism and introduce it into another organism by modifying the genotype. Genetic recombination permits new genetic combinations accelerating the genetic diversity in a particular population thereby, leading to the loss & expression of the relevant genes. Genetic recombination results in the evolution in response to the changes in the environment.

The stimuli through which a dancing scout bee communicates the location of a food source to other worker bees in a hive are 

  1. Visual

  2. Acoustic

  3. Contact

  4. Contact and visual


Correct Option: B
Explanation:

Honey bees like insects communicate through chemicals and odors. Besides these they also use specific behaviors such as dances to convey information about the availability and type of resources in the environment, and the location of the same. The dancing scout bee's body generally points in the direction of the food source and the sound produced during the dance indicates the profitability and availability of food. Hence, the scout bee uses acoustic stimuli to communicate the location and source of food to other worker bees.

In honey the percentage of maltose and other sugar is ...........%

  1. 9.2

  2. 8.81

  3. 10.5

  4. 11.2


Correct Option: B
Explanation:

Honey is mainly consists of fructose (about 38-55%) and glucose (about 31%), with remaining sugars including maltose, sucrose, and other complex carbohydrates. Maltose, sucrose and other sugars accounts for 8.8%. Hence, option B is correct.

Nobel prize winner for the discovery of method of interpersonal communication in honey bee is ......................

  1. Karl von Frisch

  2. H.G. Khorana

  3. Harvey

  4. Darwin


Correct Option: A
Explanation:

Karl von Frisch of Germany was awarded Nobel prize in 1973 for his discovery in the field of organisation and elicitation of individual and social behaviour pattern in bees. He showed that honey bees use a dance language to communicate food locations to other bees. He found two types of dance - round and waggle dance. Hence, option A is correct.

Which among the following is the real product of the honey bee?

  1. Honey

  2. Bee wax

  3. Propolis

  4. Both (B) and (C)


Correct Option: B
Explanation:

Propolis, a secondary but equally virtuous beehive product, is a component of honey secreted by honey bee itself and bee wax is real product of honey bees. 

Sting apparatus in honey bee is a modified form of ...............

  1. Ovipositor

  2. Wax glands

  3. Alkaline glands

  4. Podical valves


Correct Option: A
Explanation:

The stinging apparatus of the honey bee is a modified ovipositor (egg laying tube) that all bees and wasps have. In some bees and wasps, the ovipositor is nothing more than a simple egg-laying tube designed to get eggs into hard to reach nooks, while in others it is stiffened to allow holes to be made in wood or penetrate the bodies of other insects in order to lay eggs. As the stinger is a modified egg laying tube, only the female bees posses a sting.

A nest built by a colony of termites underground as in a tree as an artificial nest used to house termites in a laboratory.

Which of the following statement is correct?

  1. Apis indica is the largest wild honey bee.

  2. Wax is waste material of honey bee.

  3. Von Frisch discovered the news transmission methods in the honey bee.

  4. Drone of the honey bee is diploid.


Correct Option: C
Explanation:

1st statement is incorrect as Apis dorsata laboriosa and not Apis indica, the Himalayan honey bee, is the world's largest honey bee.

2nd statement is incorrect as bees 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.
3rd statement is correct as Karl Von Frisch discovered the 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. 
4th statement is incorrect as drones of the honey bee are haploid and not diplod. They develop parthenogenetically from unfertilized eggs.
Therefore, the correct answer is option C.

A typical hive contains approximately 20,000 bees classified as either the female queen (n=1), male drones (n=20), and workers (the balance of the hives population). The queen's primary function is to mate with drones and lay the eggs that give rise to the following generation, whereas the worker bees fulfill all day-to-day functions of the hive, including foraging, guarding the nest, tending to the drones and to the queen in addition to constructing the hive.
The European honey bee, Apis mellifera, is capable of producing an inhibitory signal, the stop signal, which can be triggered by encounters with dangerous conditions or organisms. This stop signal reduces recruitment of other foragers to a dangerous location. For example, A . mellifera foragers produce stop signals to inhibit waggle dancing for dangerous food sources.
A stop signal is a 300 - 400 Hz vibrational signal with a duration of approximately 150 mts that a worker usually delivers while butting its head into the body of the receiver, causing the receiver to momentarily freeze. Attacks by wasps and spiders (among other predators) elicit stop signals, which inhibit waggle dancing. However, stop signals are also used in other inhibitory contexts that are not associated with danger.
Each of the following activities plausibly stimulate foraging inhibition and contribute to the overall success of the colony except

  1. House-hunting bees speed up nest site decision-making with stop signals that inhibit recruitment for competing nest sites.

  2. Foraging bees use stop signals to communicate conditions of food source overcrowding at a particular foraging site.

  3. Guard bees use stop signals to communicate when the nest is under attack. This signal seeks to keep vulnerable bees in the safety of the nest during the period of attack.

  4. The queen secretes pheromones that inhibit reproduction among all bees other than selected drones.


Correct Option: A
Explanation:

'An' as house chasing honey bees additionally called as working drones as per the section essential capacity is to watch the home, which incorporates creating inhibitory flags or stop signals while experiencing hazardous conditions or life forms or assaults by different predators.

So, the correct option is 'House-hunting bees speed up nest site decision-making with stop signals that inhibit recruitment for competing nest sites.'
