I sometimes have several queen-rearing yards two miles apart where my nuclei are kept during the entire season—several hundred nucleus colonies are made up and at once taken away and in this way our apiaries are established, but for nuclei only. If more convenient to do so bees may be brought from a distance for forming nucleus colonies, and when this method is practiced the bees can be placed in the home yard. This plan works nicely as I have found when forming nuclei. INTRODUCING QUEENS We have now come to one of the most interesting parts of apiculture, and that part of queen-rearing that has been the cause of much trouble and a great deal of discussion for many years. When it comes to the introduction of queens, either fertile or unfertile, nearly all bee-keepers, whether experts or novices, are all at sea. In the case of introducing unfertile queens, one thing should be kept in mind, namely, the older the virgin queen the more difficult and dangerous it is to safely introduce them. Virgin queens, so far as bees are concerned, cease to be “baby” queens when they are three days old; after that it is very difficult to introduce them, though I have no trouble in introducing them successfully by using tobacco smoke. I cannot say which is the most difficult to introduce, virgin or fertile queens. It requires in either case some little experience in order to be successful. Some times bees will destroy a strange queen even when she is introduced under the most favorable conditions. No one can introduce a virgin queen successfully unless the bees to receive her have been queenless at least three days. In all my experience I have practiced but one method of introducing queens. It is what I term the three-day plan. I seldom lose a queen by it. No doubt other bee-keepers have as good methods of introducing queens as I have. But the first and last queens I have introduced were by the system given below. I cannot think of giving up a sure thing for something I know nothing about. HOW TO INTRODUCE VIRGIN QUEENS
