  QueenIntroduction and QueenAcceptanceQueenintroduction usually means replacing the queen of a colony with a younger adult queen that is laying or has been laying; the term is also understood by  beekeepers to include placing a queen cell in the colony, where the queen emerges, and from which she mates, subsequently becoming the colonys queen. Virgin queens are sometimes introduced to colonies, rather than laying queens, because of the beekeepers preference or because of difficulty in getting laying queens when needed. As a rule, virgin queens are less readily accepted by colonies than laying queens.

  It is necessary to consider some of the factors that we believe influence queen acceptance.

  The first condition for acceptance is that the colony should be queenless. There are two kinds of queenless colonies. One is the kind that has recently become queenless, by accident or because the beekeeper removed the queen; brood in various stages are present, as are adult bees of various ages and physiological development. The second kind of queenless colony has been without a queen so long that there is little or no brood, and the workers have become old. Such a colony is difficult to requeen. It is better to dispose of them and to start a new colony with bees of all ages.

  A second factor in queen acceptance is the income of nectar into the colony. During a good nectar flow almost any method of queen introduction is successful. It is wise during a dearth, or even during a light flow, to simulate a good nectar flow by feeding sugar syrup to the colony to be requeened.

  A third factor is letting bees become "conditioned" to the new queen before she is released among them. This conditioning requires a period varying from hours to days, depending on various conditions.

  A fourth factor is the condition of the queen herself. Queens undergo changes in physiology and in activities or behaviour, and introduction is easiest when the queen and colony are "in tune."

  Queen introduction is most likely to be successful when the colony to receive the queen is queenless and has a high proportion of young bees; when there is a good and constant nectar flow so that both foragers and house bees are fully occupied; and when the bees of the receiving colony are given time to become conditioned to the new queen before her release and when the queen is in the proper physiological state to match the condition of the receiving colony.

  In queen introduction, it is necessary to get the job, despite any adverse conditions.

  EXERCISESⅠ。 READING COMPREHENSION

  Select the answer which is most accurate according to the information given in the passage.

  1. can be chosen to replace the former queen of a colony.

  A. A young queen that is laying unfertilized eggs

  B. A young queen that has been laying unfertilized eggs

  C. A queen cellD. All of the above

  2. Sometimes a virgin queen is chosen to replace an old queen because .

  A. of the colonys preference or the scarcity of laying queens

  B. of the beekeepers preference towards the young or of the trouble obtaining laying queens when necessary

  C. virgin queens are expected to lay more eggs than laying queens

  D. it is much easier for a virgin queen to be accepted

  3. According to this reading passage, which of the following is not stated as one of the four factors facilitating queen acceptance?

  A. The colony has newly become queenless.

  B. It is better for the bees to become accustomed to the new queen before she is put in the colony.

  C. A good nectar flow is available.D. It is the mating period for the bees.

  4. Which of the following conditions makes it difficult for queen introduction to be carried out?

  A. The new queen has not reached maturity.

  B. Sugar syrup is used to imitate nectar flow

  C. There is little or even no brood in the colony due to the absence of a queen for a long time.

  D. The workers are old enough to perform their everyday tasks.

  5. As it is used in the passage, the phrase, "become 'conditioned to" (paragraph 5) means .

  A. become familiar withB. be interested in

  C. be friendly with       D. become accustomed to

  6. The workers in a colony can be classified into two different types: .

  A. the queen cell and the brood   B. the forager and the house bee

  C. the king and the queen     D. the virgin queen and the laying queen

  7. A virgin queen is less easily accepted by a colony than a laying queen because .

  A. it cannot lay eggs at onceB. it may cause fights among the males

  C. it has not undergone all the changes in physiology, activities or behavior, which may facilifate agreement with the colony

  D. both A and B

  8. Why is a good nectar flow so important a factor in queen introduction?

  A. It is important because all the workers will be kept too busy to pay attention to the new queen.

  B. It is important because the workers will not worry about the food for the newcomer.

  C. Because if the bees have enough nectar, any queen will do.

  D. Because the bees think food is as important as the queen.

  Ⅱ。 CONTEXTUAL REFERENCE

  Read the following two articles and figure out the meaning of the words in italics using the context given and wordbuilding skills.

  (A)

  We come now to the Hymenoptera bees, which store pollen and honey in their nests to provide food for their young. Pollen is collected by the hairs on a bees legs and body and also by specialized structures, called pollen brushes, which are found on the hindlegs and sometimes on the abdomen of female bees. After pollen is collected, it is brushed off by the insects head and feet, dampened with dew or some other form of moisture, mixed with honey from the bees mouth and formed into tiny pellets. The pellets are then pushed into the socalled pollen baskets. These baskets, consisting of long and stiff hairs on the hindlegs, hold a considerable number of pollen pellets.

  (B)

  That is one strange fact; here is another. A rainbow is red on one edge, violet on the other. Outside the violet of the rainbow there is another colour which we cannot see at all. This colour beyond the violet, invisible to us, is called the ultraviolet. Although it is invisible, we know that the ultraviolet is there because it affects a photographic plate. Now, although humans are unable to see ultraviolet light, bees can; for them, ultraviolet is a colour. Thus bees see a colour which we cannot even imagine. This has been found out by training bees to come for syrup to various parts of a spectrum, or artificial rainbow, thrown by a prism on a table in a dark room. In such an experiment the insects can be taught to fly to the ultra-violet, which for us is just darkness.

  Ⅲ。 CLOZE

  Complete the following passage by filling in the blanks with appropriate words.

  Mating time in a beehive is a busy time. Their actlvity is comparable humans      1     for a fancy wedding. Some scientists seem to     2     that mating occurs     3     the hive becomes too crowded.

  The old queen bee takes     4     half of the workers out of the     5. They go     6     swarming. Swarming is a loud,     7     crowded exit. The old queen leads; they     8     a new tree and 9     a new hive.

  Back at the hive     10     a week later, several queen bees hatch     11. The first queen out 12     the ruling queen of the     13. The workers destroy all     14     queens. The queen bee 15     out of the hive. A drone     16     follows. They mate in the air. The drones     17     fertilizes the queens eggs. The queen bee     18     to the hive. Drones are no longer    19. Just as the  20     queens are destroyed, so the workers drive the drones out of the hive.

  A queen lives about five years. She produces millions of eggs. During the one mating of her life, the drone gives her enough sperm to fertilize eggs over and over again throughast her life. The workers continue to tend, feed, and care for the queen. The workers continue to gather food and to care for the grubs(蛴螬)。 A new life cycle has been started.
