Part 7

It is not necessary to find the queen, since the presence of unsealed brood indicates In which hive body she is confined. She may be transferred to the other hive body by shaking all the bees from the combs she is known to occupy in with the bees of the other hive body. In this case some bees are returned to the shaken combs (p. 38) before this brood is set aside, to prevent its being chilled.

=Mechanical devices.=--A number of mechanical devices have been described for shifting bees from one brood chamber to another. These permit the bees to leave the hive when going to the fields and are so arranged that the returning bees are led to enter the new brood chamber. This is accomplished by means of switches in the bottom board or by a chute or tube so attached that the entrance to the old brood chamber is closed, allowing exit only through the tube which opens near the entrance of the new brood chamber. In either case the hives are so arranged that the bees returning from the field readily enter the new brood chamber. The queen is found and together with a comb of brood and adhering bees is put into the new brood chamber, and the supers are transferred from the old to the new brood chamber. The young bees as they learn to fly are added to the swarm by the same device. Otherwise the manipulation is the same as the other methods described.

=SEPARATING THE QUEEN AND BROOD WITHIN THE HIVE.=

In some swarm-control methods neither the queen nor the brood is removed from the hive, but these are temporarily separated within the hive. These methods are ordinarily used only on colonies making preparations to swarm and are practically equivalent to the dequeening plan. The following methods make use of this principle of swarm control:

(1) The queen may be placed in a wire-cloth cage within the hive or may be confined to a small comb surface within the brood chamber by means of queen-excluding zinc. No queen cells are permitted to mature, and the queen is liberated after 10 to 15 days.

(2) The queen together with a comb containing a small amount of brood is placed in a lower hive body containing no other frames or combs. After destroying all queen cells the brood is placed in a second hive body, the two hive bodies being separated by a queen-excluding honey board and the supers adjusted above the brood as before. The queen, being separated from the brood by means of the excluder, lays few eggs in the comb on which she is confined during this period of separation. After a week or 10 days the queen cells are again destroyed, and the brood and queen are put back into a single hive body as before. This method gives results quite similar to the dequeening method (p. 35).

If every season were alike in a given locality the beekeeper could work out a manipulation to be applied to each colony just before or at the beginning of the honey flow, which would result in practically no swarming. The wide variation in the seasons, however, renders it next to impossible to adopt a swarm-control measure that will prove most profitable every year. The means of control adopted must be such as to favor the domination of the storing instinct. Probably the plan of making weekly visits is the most widely used system of swarm control by manipulation. When a colony is found preparing to swarm, the brood is removed if conditions are such as to justify doing so (p. 37). Otherwise the removal of the queen is resorted to.

With any of these methods of control the colony may rapidly restore former conditions, and even though it has been diverted from swarming may later again prepare to swarm and require a second manipulation. Generally speaking, when the honey flow is short, less radical measures are required. Colonies that have been supplied with young queens after a period of queenlessness have one factor (the queen) changed with at least some degree of permanency. Colonies that have been compelled to construct a new set of brood combs from narrow strips of foundation have the most radical change of conditions as to brood rearing. Either of these changes alone is usually sufficient to insure no further preparations to swarm.

=Manipulation of the Supers.=

Proper manipulation of the comb-honey supers is not only a strong factor in the prevention of swarming but is also a stimulus to storing. The amount of room the colonies should have in the surplus apartment varies so much that the ordinary standard super is simply a unit in a large and flexible surplus apartment. If enough surplus room is given at the beginning of the season for the storage of the entire crop of honey, the space so given is too great for best results at the beginning of the honey flow, and little of it is needed at all if the season is poor. If, on the other hand, a single super is given and no other added until the first is completed, the room in the surplus apartment decreases from the time the super is given until the combs are completely drawn out, when there is little space left between the combs, the bees being practically crowded out. Thus while the population of the colony is increasing their room is being diminished--a condition highly conducive to swarming and less energetic work. After the super is filled, it is some time before the honey is ripened and sealed, ready to be removed. During this interval, if no other supers are given, there is no place for storage of the incoming nectar, and the comb builders must remain idle or waste their wax in building burr and brace combs. To avoid loss in this way, empty supers are added as they are needed, and the comb builders move from one super to another as their work in each is completed. The surplus apartment, whether consisting of a single super or several supers, should at all times contain some space for the comb builders.

If the honey flow is heavy and promises to continue, it is desirable to furnish not only sufficient room but to induce the bees to begin work in as many sections as possible, giving large comb surface for the storage and evaporation of the thin nectar, thus in a measure approximating extracted honey conditions.

There is a danger, however, that if the bees are induced to extend their work through too many supers, the sections when completed will be less well filled and therefore lighter in weight. Also, if the honey flow should not continue as expected a rapid expansion of the surplus apartment results in a large number of unfinished sections.

The rapidity of the expansion of work in the supers may to some extent be regulated by the position of each newly added super. If a rapid expansion is desirable, the empty super is placed below the supers already on the hive, while if it seems best to crowd the bees somewhat the empty super is placed above those already on the hive. When the empty super is placed above the partly finished ones, the bees do not begin work therein unless they need the room. This practice is always desirable during a slow honey flow or toward the close of any honey flow, but when nectar is coming in rapidly does not result in a rapid expansion of comb building sufficient to avoid a more or less crowded condition, which in turn causes a loss of honey and increases the probability of swarming. If each super is supplied with one or two extracting combs (p. 16), this disadvantage of the practice of placing the empty super on top largely disappears, since the extracting combs are immediately available for the storage of nectar.

When the empty supers are placed under the partly filled ones, work in them is commenced promptly, but this may be at the expense of the nearly completed sections, which by this plan are moved farther from the brood chamber as each empty super is added. In the case of the super in which the honey is being sealed this distance is an advantage in so far as the whiteness of the cappings is concerned, but it may retard the completion of the work. An arrangement of the supers that to some extent avoids this difficulty is as follows: Except toward the close of the season, place each newly added super next to the brood chamber and keep the one nearest completion just above it with all others arranged above these two, the one in which least progress has been made being on top (fig. 19). Thus super No. 1 is raised up and No. 2 placed beneath it. When No. 3 is given, it is placed next to the brood chamber, while above it is No. 1 with No. 2 on top. If No. 4 is given, it is placed next to the brood chamber with Nos. 1, 2, and 3 in order above it. By this arrangement, if conditions justify doing so, strong colonies may be induced to expand their surplus apartment with great rapidity, since as soon as the foundation is well drawn in each newly added super it may be transposed to the top and an empty one put in its place. Such rapid expansion of work in the supers should not be attempted, however, except during a heavy honey flow.

If early in the honey flow the bees are storing rapidly, strong colonies should be given a second super as soon as work has been fairly begun in the first. Colonies of medium strength may of course be allowed to do considerable work in the first super before the second is given, while a weak colony may have sufficient room for comb building until the first super is almost completed. The first super should contain some empty comb when given to the colony, and each succeeding super should be given in advance of the time when the bees would be in any way crowded without it. At no time should all the sections be removed and new supers containing only foundation be given, but the surplus apartment should contain sections in all the various stages of development. In this way there is no break in the work in the supers, and the critical periods, so far as the super room bears upon the problems of swarming and energetic work, are largely eliminated.

During the latter part of the honey flow the reasons for further expansion of the surplus apartment in excess of the immediate needs of the colonies (p. 41) no longer exist. At the beginning of a good honey flow the maximum of new work consistent with well-filled sections is desirable, while toward the close of the flow the beekeeper desires the minimum of new work consistent with sufficient room. The precise period when further expansion of the surplus apartment is no longer desirable and a concentration of the work already begun should take place is sometimes difficult to determine, and to do so requires a thorough knowledge of the locality and good judgment on the part of the beekeeper.

It is usually desirable to remove the honey as soon after it is finished as can well be done. If it is left on the hives too long after it is finished, it is likely to become discolored or "travel stained," while if it is taken off too soon some of the sections are not completed. It is desirable that the honey be removed by entire supers instead of by individual sections, therefore conditions should be made as favorable as possible for the completion of all the sections in a super without the more advanced ones becoming "travel stained." The bees are more inclined to stain the white surface of the combs toward the close of the honey flow or during very slow flows. Trouble from this source is at such time intensified because of the uneven progress of work in the different sections, the more advanced sections therefore being sealed some time before the super is sufficiently advanced to justify its removal. Another form of discoloration is brought about by the honey being sealed in close proximity to old and dark brood combs, in which case some of the darker wax from the old combs is sometimes apparently used for capping the honey.

During a good honey flow all except the last supers may be left upon the hives until all or nearly all of the sections of honey are sealed, since (1) there is little trouble from "travel stain" when work is progressing rapidly, (2) all the sections in the super are ready to be sealed at about the same time, and (3) when there are several supers on each hive the one in which the honey is being sealed is at least one super removed from the brood combs.

Toward the close of the honey flow all supers having most of their sections finished should be removed and the sections sorted. The unfinished sections should be graded according to the degree of completion, the various grades placed in supers and given to such colonies as are most likely to finish them. Every effort should be made at this time to contract the surplus apartment, concentrating the work upon the sections nearest completion. All supers in which work has not yet been started should be removed and as soon as possible the surplus apartment of each colony should be reduced to one super. Though little room is necessary during the close of the honey flow, there should always be some room for the storage of new nectar until it is ripened. For such conditions extracting combs are valuable, since, instead of giving the last comb-honey super in which little work would be done, a set of extracting combs may be placed over the sections to afford room for the incoming nectar and comb surface for its ripening.

=CARING FOR THE CROP.=

=Removing the Honey from the Hives.=

If the honey flow is of considerable duration the major portion of the crop is removed before the flow ceases. At this time the removal of the finished supers is comparatively easy because the bees can readily be driven from them and also because the operator is not hindered in his work by robbing bees. At the close of the honey flow all the supers remaining upon the hives should be removed promptly, since to leave them on would result not only in some of the honey being carried down into the brood chamber but also in badly propolized sections. After the honey flow has ceased, great care should be exercised to keep bees from robbing. The use of bee-escapes (fig. 12) greatly facilitates the removal of the honey at any time, but their use is especially desirable in removing the honey remaining on the hives at the close of the honey flow. By their use the honey may be removed and stored in the honey house with little disturbance or excitement among the bees. The supers of honey should of course be taken directly to the honey house or kept well covered from robbers.

Honey from out-apiaries should be loaded for transportation in such a manner that the bees can not get at it, then before the horse is hitched to the wagon the load of honey should be drawn by hand some distance from the apiary if the slope of the ground will permit doing so. If this is not possible the horse may be attached by means of a long rope and the load drawn to a safe distance before the horse is hitched to the wagon.

Before finally storing the supers of honey in the honey room those that are but partly filled may have their sections removed and sorted. The unfinished sections that can not be disposed of at a profit locally are usually put back into supers and the honey they contain is fed to the bees. This feeding is done by simply exposing the supers where the flying bees can have access to them. If there are few supers compared with the number of colonies they should be placed in piles and only a small entrance allowed, since if free access were given to a large number of bees they would tear the combs to pieces. When the bees have finished removing the honey from these unfinished sections the latter may be stored for future use as "bait" sections.

=Care of Comb Honey.=

In the honey room the supers of honey should be placed in piles in such a manner as to allow a free circulation of air between them. This may be done by "sticking them up" as lumber is piled to dry or by placing alternate supers crosswise. The air in the honey room should be kept as dry as possible. This is usually accomplished by means of a high temperature, the honey room being located on the sunny side of the building or directly under the roof. The windows should be opened only during dry weather. Ventilation of the honey room is of no value except when the air that is admitted contains less moisture than that already present. Otherwise ventilation may be a positive detriment. If a protracted period of rainy or damp weather should occur while the honey is in this storage it may be necessary to use artificial heat to dry the air in the honey room. Any great variation in temperature should be avoided, since it may cause a condensation of moisture on the surface of the cappings which will be absorbed by the honey.

Some beekeepers find it necessary to fumigate comb honey to prevent damage by the larvæ of the wax moth. For this purpose sulphur fumes or bisulphid of carbon may be used. If bisulphid of carbon is used, great care should be taken not to bring it near a flame, as it is highly inflammable.
