9-Hydroxydec-trans-2-enoic acid, a pheromone stabilizing honeybee swarms National Institute of Agronomic Research
Butler, C.G.; Callow, R.K.; Chapman, J.R..
A colony of honeybees (Apis mellifera L.) deprived of its hive and combs behaves like a reproductive swarm and will cluster on any convenient support. When the queen is taken away from such an artificial swarm, the workers soon become restless and increasing numbers fly off until eventually the cluster breaks up altogether.

A new design of microsyringe tip for the instrumental insemination of queen honey-bees National Institute of Agronomic Research
Butler, C.G..
IN 1927, Watson described the construction of a number of glass microsyringes which he had used for the instrumental insemination of queen honey-bees. The tips of these syringes were straight and the operator holds one of these syringes in line with the long axis of the queen when, introducing it into her vagina. This type of glass syringe was simplified and improved during the course of time both by Watson himself and also by Nolan and others; but really satisfactory results were infrequently obtained at this stage.

Experiments on the poisoning of honeybees by insecticidal and fungicidal sprays used in orchards National Institute of Agronomic Research
Butler, C.G.; Finney, D.J.; Schiele, P..
Losses of bees by poisoning have been greatly increased in recent years by the growing practice of applying insecticidal and fungicidal sprays to fruit trees. Preliminary laboratory tests showed that, of the common constituents of spray mixtures, only lead arsenate and flowers of sulphur were likely to cause serious honeybee poisoning, though Derris emulsion may cause slight poisoning. Syrup containing lime sulphur, nicotine sulphate, or copper sulphate was strongly repellent to the bees. It seemed possible that spray mixtures might be made repellent to the honeybee by the addition of suitable substances. Further trials showed that lead arsenate solution, at least in the concentrations normally used, was no more attractive to the bee than distilled water....

Further investigations on the value of electric heating of beehives National Institute of Agronomic Research
Butler, C.G..
A set of twenty-four colonies of honeybees was divided into three groups, two of which received different intensities of artificial heat, applied by means of specially designed heating frames placed in the middle of the brood chambers, from 2 Jan. to 16 Mar. 1942. Heating the colonies reduced the area of brood present at the beginning of May without noticeably affecting the consumption of carbohydrate stores and thus had an adverse effect on the colonies. This conclusion is in agreement with that reached as a result of earlier work (Butler & Cockbill, 1942.) Colonies in hives fitted with top entrances were no stronger in the spring than colonies in hives with bottom entrances, nor did they show any significant difference in store consumption. No...

The behaviour of worker honeybees at the hive entrance National Institute of Agronomic Research
Butler, C.G.; Free, J.B..
1. Observations at hive entrances have been made to ascertain the relative importance of scent and behaviour in enabling a guard bee to recognise members of her own colony and to distinguish them from intruders from other colonies. 2. Guard bees are not present at the hive entrance unless the colony has been alerted. 3. Alerting of colonies is brought about by the presence of robber bees or by numbers of bees that have strayed from other colonies. 4. Guard bees attempt to intercept and inspect other bees on the alighting-board of the hive. Bees of various ages undertake guard duties. 5. Guard bees recognise members of their own colony by scent. 6. Robber bees are recognised by behaviour when attempting to enter the hive, but all other intruders are...

The control of ovary development in worker honeybees (Apis mellifera) National Institute of Agronomic Research
Butler, C.G..
Während Übereinstimmung darüber erreicht worden ist, dass die Arbeitsbienen eine ovarienhemmende Substanz von ihren Königinnen erhalten, ist es weder klargestellt worden, wie diese Substanz unter die Arbeitsbienen verteilt wird, noch ob die Königin eine psychische Wirkung auf sie ausübt. Wenn die Versuchsresultate vonVoogd undButler sowie die Resultate dieser Arbeit zusammen betrachtet werden, scheint es klar, dass ein Extrakt dieser Substanz, wenn er an weisellose Arbeiterinnenverfüttert wird, eine deutliche Hemmwirkung auf die Ovarienentwicklung ausübt. Die Versuchsresultate deuten jedoch darauf hin, dass diese Substanz wirkungsvoller ist, wenn sie den Arbeitsbienen auf dem Körper einer toten Biene, oder dem Modell einer Biene, dargeboten wird, als wenn...

The efficiency of a honeybee community National Institute of Agronomic Research
Butler, C.G..
A community of honeybees is an integrated group, the members of which can distinguish other members from intruders. Individual bees can pass on detailed information about the nature and location of food sources ; they will produce a new queen only when the old one is no longer satisfactory. These different functions are discussed and illustrated in this article ; the discussion of queen rearing is made particularly appropriate by the recent discovery of the chemical nature of queen substance. The photographs are by Treat Davidson.

The importance of perfume in the discovery of food by the worker honeybee (Apis mellifera L.) National Institute of Agronomic Research
Butler, C.G..
There is a natural tendency for untrained scouting bees to associate certain perfumes with food (e.g. those of the flowers of Crataegus oxyacantha and Trifolium repens) whereas the perfume of some other flowers (e.g. Spirea arguta) are unattractive to the honeybee. If the perfume of a new crop of flowers is sufficiently strong it will sometimes attract scouting bees when they are still unable to see the flowers. It is often necessary for a bee to approach within an inch or so of a flower before she can discern any perfume it may possess. When a bee approaches an object closely enough any attractive perfume it may possess tends to act as a stimulus to further exploration which involves settling upon the object and possibly seeking food in any small crevice...

The introduction of virgin and mated queens, directly and in a simple cage National Institute of Agronomic Research
Butler, C.G.; Simpson, J..
1 - When old (12-28 days) or young (1-5 days) virgin queens were introduced directly (without caging) to colonies from which old or young virgin queens had just been removed, it was much easier to introduce a queen to a colony from which a similar queen had been removed than to one from which a dissimilar queen had been removed. Experiments with mated and laying queens of different ages suggested that this principle is a general one, although the most marked differences are between young and old virgin queens. 2 - Old virgin queens and young laying queens were the most difficult to introduce directly to any type of colony. 3 - When a large-mesh cage was used in introducing mated tested queens to colonies which had just been dequeened, at least 90% sucess...
