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 comparative study of the dorval vessels of bees National Institute of Agronomic Research
Wille, Alvaro.
Two main types of dorsal vessels were found in the 101 species dissected, representing 61 genera and including most of the major groups of bees. In one type the dorsal vessel is straight and ruris dorsal to the gut; in the other type it makes an arch between the dorsal longitudinal muscles of the thorax, sometimes with a series of loops just behind the ascending portion. Intermediate types occur. Within any family or tribe in which both main types occur, that with the straight thoracic portion is always found in the primitive forms; and vessels with a series of loops are found only in the most specialized bees. An evolutionary trend is evident toward reduction of the posterior section of the dorsal vessel and its ostia. In the Meliponini, or stingless...

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.

A survey of the incidence of Nosema disease (Nosema apis Zander) of the honey bee in south Australia National Institute of Agronomic Research
Doull, Keith; Cellier, K.M..
A 2-year survey of the incidence cf nosema disease of the honey bee in South Australia bas shown that a spring peak of infection may be expected each year. The level of infection is at a minimum in midsummer and winter but a rise may occur in the autumn. It was considered that the disease, either in the form of a few infected bees or of spores on the combs, was present in all hives throughout the survey. Significant differences in the level of infection between hives in the same apiary suggested that there may be factors, varying in some way from hive to hive, which determine the level of infection within each hive. In view of the appreciable variation between hives it is evident that the incidence of the disease in individual hives was estimated with...

A theory of the causes of development of epizootics of nosema disease of the honey bee National Institute of Agronomic Research
Doull, Keith M..
A hypothesis is presented to explain the developments of epizootics of nosema disease of the honey bee, Apis mellifera Linnaeus. It is assumed that most hives contain some lightly infected carrier bees in which the numbers of the parasite increase very slowly. But under the influence of certain conditions the parasites within these bees increase in numbers very quickly, and, if other conditions are favorable, an epizootic of the disease will develop. A hypothetical course of development of an epizootic is described. It is suggested that the numbers of the parasite increase when the metabolism of infected bees is changed so as to change the environment of the intracellular parasites. Changes in the metabolism of infected bees are considered to be stress...

Acarapis mites of the honey bee, Apis mellifera Linnaeus National Institute of Agronomic Research
Eckert, J.E..
A review of references on Acarapis woodi (Rennie) indicated that this acarapis mite is not as serious as has generally been stated in American beekeeping literature. It is not considered to be the cause of Isle of Wight disease of bees. The quarantine against the importation of honey bees into the United States, except from Canada, is based on the probable effect this pest might have on the beekeeping industry. The rediscovery of an external acarapis mite in the United States in 1959, raised the question as to the actual relationship of acarapis mites to bees. The two external mites, Acarapis dorsalis Morgenthaler and Acarapis externus Morgenthaler were subsequently found to be widely scattered in Canada and the United States without any visible symptoms...

Acetylcholine in the larval food, honey, and stored pollen of a stingless bee, Melipona quadrifasciata National Institute of Agronomic Research
Welsh, John H.; Nogueira-Neto, Paulo; Jaeger, Celso P.; Ancona Lopez, Ana Amelia.
1) Using several methods, the larval food of Melipona quadrifasciata was found to contain amounts of acetylcholine estimated to range between O. 5 and 2.0 mg. equivalents of acetylcholine chloride per gram of larval food. Similar amounts have been reported for the larval food of the honey, bee, Apis mellifera. 2) The larval food of M. quadrifasciata was also found to contain a large amount of choline and an unidentified substance that was soluble in ethanol, gave a blue fluorescence, reacted with Dragendorf's reagent, and had a weak acetylcholine-like action. In one sample of larval food, a substance with the properties of glycine betaine was also found. 3) Samples of stored pollen were also found to contain acetylcholine, choline and the unidentified...

Acute infection of bees with paralysis virus National Institute of Agronomic Research
Bailey, L.; Gibbs, J..
Acute bee paralysis virus (ABPV) occurs commonly in adult honey bees (Apis mellifera Linnaeus) in Britain. The amount of the virus in different bees differs, as does the proportion of infected bees in different colonies. No organ or part of a bee, or feces, was found to be invariably free of virus. Bees fed either by other bees that had been infected with pathogenic doses of ABPV, or with food containing up to 10(10) particles of ABPV, did not become obviously diseased but the virus content of their tissues temporarily increased. However, bees either fed with at least 10(11) ABPV particles each, or injected with at least 10(2) particles, became diseased and died, and their abnormal behavior was possibly attributable to the changes observed in their brains....

Ætiology of european foul brood ; a disease of the larval honey-bee National Institute of Agronomic Research
Bailey, L..
THE cause of European foul brood was originally thought to be Bacillus alvei or a mixture of B. alvei and Streptococcus apis. The causative organism was later named and described by White as Bacillus pluton, a lanceolate Gram-positive bacterium. This organism is the first of several which have been found to appear in diseased larvæ. However, White and others failed to culture B. pluton in vitro and it was afterwards considered to be a dissociant form of Bacillus alvei, of Bacterium eurydice, or of both. Others have maintained that B. pluton is a separate organism. It has been pointed out that Streptococcus pluton would be a more suitable designation than Bacillus pluton both on morphological grounds and in the absence of evidence that it forms spores. For...

Amoeba disease in the queen honeybee National Institute of Agronomic Research
Örösi-Pal, Z..
Queen honeybee have hitherto been found resistant to Malpighamoeba mellificae. For example 516 queens were examined by the author in1954-61, and none was infected. He has now found amoeba cysts in 3 out of 7 dead queens wintered in cages with attendant workers (instead of in a colony). Reasons for this difference between queens free in colonies and caged in incubators are discussed.

Bacillus larvae : its cultivation in vitro and its growth in vivo National Institute of Agronomic Research
Bailey, L.; Lee, D.C..
Spores of Bacillus larvae White germinate and make initial vegetative growth best in a limited range of low redox potentials, but later growth and sporulation occur best aerobically. Different media needed for best results with each phase of development of the bacillus are described. Spores of B. larvae germinate in the mid-gut contents of honey-bee larvae up to 2 days old. The vegetative forms then migrate and become closely applied to, but do not penetrate, the mid-gut epithelium. Most organisms seem to be voided with the contents of the intestine when an infected larva defaecates shortly before it pupates. A few organisms are presumably left in the intestine and probably invade the tissues of the larva as it pupates.

Beobachtungen zur unterschiedliche erblichen disposition von zuchtlinien von apis mellifica L. für die schwarzsucht National Institute of Agronomic Research
Drescher, Wilhelm.
Under honeydew flow conditions, honeybee colonies with queens of defined origin proved to be especially liable to paralysis. The tendency was irrespective to the mating drone. The observation suggest a matrocline heredity of the honeybee. The liability for the disease is considered to be a symptom of inbreeding. The worker bees' behaviour towards those bees that had died of paralysis on the combs in the hive is described.
