Age of nurse bees and brood rearing National Institute of Agronomic Research
Haydak, Mykola H..
Nurse bees were forced to rear brood continuously, under field and laboratory conditions. The weight and the length of life of the bees they reared decreased when the nurse bees were much older than is normal (40-98 days instead of 5-16 days). Intestines of emerged bees reared by nurse bees 50 days old and more were very fragile. In the control colonies these phenomena were not observed.

Discharge and manipulation of labial gland secretion by workers of Apis mellifera L. (Hymenoptera : Apidae) National Institute of Agronomic Research
Simpson, J.; Riedel, Inge B.M..
An account is given of the salivation process in Apis mellifera. The mechanisms by which the hairs of the tongue are erected and the ligula retracted, and the action of the salivary pump, are described, and their effect on the discharge of saliva and intake of food are discussed.

E-β-ocimene a new volatile primer pheromone that inhibits worker ovary development in honey bees Inra
Maisonnasse, A.; Lenoir, J.C.; Costagliola, G.; Beslay, D.; Crauser, D.; Plettner, E.; Le Conte, Y..
Dans une colonie d’abeilles sans reine ni couvain, les ouvrières tendent à devenir fertiles etinvestir leur énergie dans la ponte d’oeuf non-fécondés. Afin de maintenir une certainestabilité dans l’organisation de la colonie et prévenir ce détournement de l’investissementénergétique des ouvrières, la reine garantie son statut de seule reproductrice et le couvainaccapare le soin des ouvrières. Pour cela, ils émettent des phéromones peu volatiles. Laphéromone mandibulaire (principalement le 9-ODA) émis par la reine ainsi qu’un mélange de10 esters émis par le couvain. Ces composés permettent une castration chimique partielle desouvrières. Cependant, parmi les deux facteurs de régulation de la maturation ovarienne desouvrières, il semble que la présence de...

Occurence of ovary-developed workers in queenright colonies of stingless bees National Institute of Agronomic Research
Sakagami, Shoichi F.; Beig, Darvin; Zucchi, Ronaldo; Akahira, Yukio.
The worker ovaries of 16 species of stingless bees and two subspecies of European honeybee were studied under the queenright condition. In contrast to the honeybee, which showed, as already well known, no trace of ovary-development, the ovary-developed workers were observed in the nurse bee stage of ail stingless bee species, in a very high frequency, except for Trigona freiremaiai (Moure), T. (Meliponula) bocandei (Spinola) and T. (Partamona) cupira Smith. In the observation in T. (Scaptotrigona) postica Latreille, the ovaries were still rudimentary at emergence, developed at the stage of nurse bee in parallel to the pollen intake, then degenerated in the subsequent stages. Histologically, the ovary development follows the manner seen in other polytropic...

Respiration rates of worker honeybees of different ages and at different temperatures National Institute of Agronomic Research
Allen, M. Delia.
1. The respiration rates of individual adult worker bees confined in small gauze cages were determined over a range of temperatures between 7 and 46° C. The respiration rates usually remained constant over a period of 1 hr., although at 7, 12° C., and possibly at 17° C. there were indications of a decrease with time, and at 42 and 46° C. indications of an increase with time. Fluctuations which would have reflected variable activity during any of the experiments were rare. 2. At each temperature studied the respiration rates increased progressively from the youngest adults (newly emerged) to the oldest measured (24-33 days). The increase was particularly marked during the first few days of adult life. 3. The respiration rates of newly emerged and 18 hr....

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 effect of mandibular gland extirpation on the longevity and attractiveness of workers of queen honey bees, apis mellifera National Institute of Agronomic Research
Zmarlicki, Cyprian; Morse, Roger A..
The mandibular glands were extirpated from 6 of 12 mated, sister queen honey bees, 1 month old. Two of the modified and five of the untreated queens survived after being held for about 11 months in otherwise normal colonies. The modified queens were almost completely unattractive to worker bees at the end of the experiment. The brood quantity and quality in the colonies headed by modified queens was not very dissimilar from those found in the check colonies.

The occurrence and possible significance of the "shaking" of honeybee queens by the workers National Institute of Agronomic Research
Allen, M. Delia.
1. The phenomenon of "shaking" in honeybee colonies is described, and is here considered in relation to the queen of the colony. 2. The queen was rarely shaken in the spring but once swarm preparations had commenced the frequency of shaking rose rapidly, reaching a peak at about the time the swarm left. A newlymated young queen was shaken to some extent just after she first commenced laying, but within a few days the frequency had fallen markedly, and finally no shaking was observed. Since the queens were shaken only at times when they were likely to fly out of the hive it is concluded that there is a connection between the two events. Hammann (1957) gives results on unmated queens which also support this assumption, for these queens were shaken with...

The transmission of food between worker honeybees National Institute of Agronomic Research
Free, J. B..
1. A study has been made of the behaviour patterns associated with food transmission between worker honeybees. 2. There is a general tendency for food to pass from the older to the younger workers of a colony, although there is a considerable passage of food in the opposite direction. Younger bees generally receive food more frequently than they give it. 3. As worker bees grow older, the mean ages of the bees that feed them and to whom they give food also increase. 4. Although bees about to give food generally have more in their honeystomachs than those about to receive it the quantities of food contained in the honeystomachs of bees in these two groups overlap considerably. The transmission of ‘queen substance’, the occupation on which a bee is...
