If natural swarming is allowed, after-swarms may be prevented from issuing, by cutting out all the queen cells but one, soon after the first swarm leaves the hive; or if it is desired to have as fast an increase of stocks, as can possibly be obtained from natural swarming, then instead of leaving the combs in the parent hive to be attacked by the moth, a certain portion of them may be taken out, when swarming is over, and given to the second and third swarms, so as to aid in building them up into strong stocks.
But I have not yet spoken of the most fruitful cause of the desolating ravages of the bee-moth. If a colony has lost its queen, and this loss cannot be supplied, it must, as a matter of course, fall a sacrifice to the bee-moth: and I do not hesitate to assert that by far the larger proportion of colonies which are destroyed by it, are destroyed under precisely such circumstances! Let this be remembered by all who have any thing to do with bees, and let them understand that unless a remedy for the loss of the queen, can be provided, they must constantly expect to see some of their best colonies hopelessly ruined. The crafty moth, after all, is not so much to blame, as we are apt to imagine; for a colony, once deprived of its queen, and possessing no means of securing another, would certainly perish, even if never attacked by so deadly an enemy; just as the body of an animal, when deprived of life, will speedily go to decay, even if it is not, at once, devoured by ravenous swarms of filthy flies and worms.
In order to ascertain all the important points connected with the habits of the bee-moth, I have purposely deprived colonies in some of my observing hives, of their queen, and have thus reduced them to a state of despair, that I might closely watch all their proceedings. I have invariably found that in this state, they have made little or no resistance to the entrance of the bee-moth, but have allowed her to deposit her eggs, just where she pleased. The worms, after hatching, have always appeared to be even more at home than the poor dispirited bees themselves, and have grown and thrived, in the most luxurious manner. In some instances, these colonies, so far from losing all spirit to resent other intrusions, were positively the most vindictive set of bees in my whole Apiary. One especially, assaulted every body that came near it, and when reduced in numbers to a mere handful, seemed as ready for fight as ever.
How utterly useless then, for defending a queenless colony against the moth, are all the traps and other devices which have been, of late years, so much relied upon. If a single female gains admission, she will lay eggs enough to destroy in a short time, the strongest colony that ever existed, if once it has lost its queen, and has no means of procuring another. But not only do the bees of a hive which is hopelessly queenless, make little or no opposition to the entrance of the bee-moth, and to the ravages of the worms, but by their forlorn condition, they positively invite the attacks of their destroyers. The moth seems to have an instinctive knowledge of the condition of such a hive, and no art of man can ever keep her out. She will pass by other colonies to get at the queenless one, for she seems to know that there she will find all the conditions that are necessary to the proper development of her young. There are many mysteries in the insect world, which we have not yet solved; nor can we tell just how the moth arrives at so correct a knowledge of the condition of the queenless hives in the Apiary. That such hives, very seldom, maintain a guard about the entrance, is certain; and that they do not fill the air with the pleasant voice of happy industry, is equally certain; for even to our dull ears, the difference between the hum of the prosperous hive, and the unhappy note of the despairing one, is sufficiently obvious. May it not be even more obvious to the acute senses of the provident mother, seeking a proper place for the development of her young?
The unerring sagacity of the moth, closely resembles that peculiar instinct by which the vulture and other birds that prey upon carrion, are able to single out a diseased animal from the herd, which they follow with their dismal croakings, hovering over its head, or sitting in ill-omened flocks, on the surrounding trees, watching it as its life ebbs away, and stretching out their filthy and naked necks, and opening and snapping their blood-thirsty beaks that they may be all ready to tear out its eyes just glazing in death, and banquet upon its flesh still warm with the blood of life! Let any fatal accident befall an animal, and how soon will you see them, first from one quarter of the heavens, and then from another, speeding their eager flight to their destined prey, when only a short time before, not a single one could be seen or heard.
I have repeatedly seen powerful colonies speedily devoured by the worms, because of the loss of their queen, when they have stood, side by side with feeble colonies which being in possession of a queen, have been left untouched!
That the common hives furnish no available remedy for the loss of the queen, is well known: indeed, the owner cannot, in many cases, be sure that his bees are queenless, until their destruction is certain, while not unfrequently, after keeping bees for many years, he does not even so much as believe that there is such a thing as a queen bee!
In the Chapter on the Loss of the Queen, I shall show in what way this loss can be ascertained, and ordinarily remedied, and thus the bees be protected from that calamity which more than all others, exposes them to destruction. When a colony has become hopelessly queenless, then moth or no moth, its destruction is absolutely certain. Even if the bees retained their wonted industry in gathering stores, and their usual energy in defending themselves against all their enemies, their ruin could only be delayed for a short time. In a few months, they would all die a natural death, and there being none to replace them, the hive would be utterly depopulated. Occasionally, such instances occur in which the bees have died, and large stores of honey have been found untouched in their hives. This, however, but seldom happens: for they rarely escape from the assaults of other colonies, even if after the death of their queen, they do not fall a prey to the bee-moth. A motherless hive is almost always assaulted by stronger stocks, which seem to have an instinctive knowledge of its orphanage, and hasten at once, to take possession of its spoils. (See Remarks on [Robbing].) If it escape the Scylla of these pitiless plunderers, it is soon dashed upon a more merciless Charybdis, when the miscreant moths have ascertained its destitution. Every year, large numbers of hives are bereft of their queen, and every year, the most of such hives are either robbed by other bees, or sacked by the bee-moth, or first robbed, and afterwards sacked, while their owner imputes all the mischief that is done, to something else than the real cause. He might just as well imagine that the birds, or the carrion worms which are devouring his dead horse, were actually the primary cause of its untimely end. How often we see the same kind of mistake made by those who impute the decay of a tree, to the insects which are banqueting upon its withering foliage; when often these insects are there, because the disease of the tree has both furnished them with their proper aliment, and deprived the plant of the vigor necessary to enable it to resist their attack.
The bee keeper can easily gather from these remarks, the means upon which I most rely, to protect my colonies from the bee-moth. Knowing that strong stocks supplied with a fertile queen, are always able to take care of themselves, in almost any kind of hive, I am careful to keep them in the state which is practically found to be one of such security. If they are weak, they must be properly strengthened, and confined to only as much space as they can warm and defend: and if they are queenless, they must be supplied with the means of repairing their loss, or if that cannot be done, they should be at once broken up, (See Remarks on [Queenlessness], and [Union of Stocks],) and added to other stocks.
It cannot be too deeply impressed upon the mind of the bee-keeper, that a small colony ought always to be confined to a small space, if we wish the bees to work with the greatest energy, and to offer the stoutest resistance to their numerous enemies. Bees do most unquestionably, "abhor a vacuum," if it is one which they can neither fill, warm nor defend. Let the prudent bee-master only keep his stocks strong, and they will do more to defend themselves against all intruders, than he can possibly do for them, even if he spends his whole time in watching and assisting them.
