    Description / Table of Contents: Summary This constitutes an up-to-date review of our knowledge concerning the biological properties of the various lipid fractions isolated from queen and worker honeybees. Particular attention is given to pherormone I, which inhibits queen rearing, and to the mixture pherormone I + pherormone II, which is an attractant for young worker bees, and inhibits ovogenesis.
    Abstract: Zusammenfassung Diese Arbeit bildet eine Zusammenfassung unserer heutigen Kenntnisse über die verschiedenen Lipid Fraktionnen welche aus Bienenköniginnen und Arbeiterinnen isoliert wurden. Besondere Aufmerksamkeit wird dem Pherormon I zugewendet, das den Aufbau der Weiselzellen hemmt, sowie dem Pherormon I + Pherormon II Komplexe, das als Lockstoffe auf die Arbeiterinnen wirkt, und die Eierbildung bei denselben unterbildet.
    Notes: Résumé Cette revue fait le point de connaissances concernant les propriétés biologiques des différentes substances lipidiques isolées des ouvrières et des reines d'abeilles. On insiste plus particulièrement sur la phérormone I inhibitrice de la construction des cellules royales, et sur le complexe phérormone I + phérormone II, attractif pour les jeunes abeilles ouvrières, et inhibiteur de leur oveogénèse.

    Notes: Conclusion De ces considérations générales sur les odeurs, il faut surtout relenir: - D'une part, quel'odeur résulte de l'excitation d'un organe récepteur spécifique. Sa mise en évidence est donc liéa à l'état réactionnel de l'appareil sensoriel — ou mieux de l'organisme — soumis à une stimulation. Elle dépend alors de l'intensité du stimulus et de l'intégraté des structures organiques. - D'autre part, quela sensibilité olfactive est en relation avec l'état physiologique de l'individu. Son étude devra donc tenir compte de la situation de carence ou de réplétion du suject, de son cycle biologique, de son état de maturation et de son sexe. Il est donc indispensable de bien connaitre le matériel qui doit servir à une expérimentation portant sur la perception olfactive.

    Description / Table of Contents: Résumé 1 A 20° C après l'hibernation la séquence des œufs d'une reineMyrmica rubra L. montre les particularités suivantes: a) le taux de production s'élève pendant les trois premières semaines jusqu'à un maximum. Ceci se maintient pour 3–4 semaines, puis décline peu à peu jusqu'à zéro après 16 semaines; b) la dimension des œufs décline pendant la période quand le taux s'augmente, puis reste à une minimum valeur constante; c) les œufs prédisposés à devenir ouvrières sont parmi ceux pondus quand le taux s'approche du maximum et la dimension s'approche du minimum. D'autres œufs, les plus gros pondus en premier et les normaux qui viennent plus tard, entrent en diapause dans les mêmes conditions de culture. 2 Les reines peuvent donner ou beaucoup ou très peu d'œufs prédisposés à devenir ouvrières. Les deux types de reine peuvent se trouver dans la même colonie, ou les colonies peuvent en avoir seulement un type, et les intermédiaires peuvent être peu nombreux. La différence paraît être dû à l'âge, car les jeunes reines pondent une très grande proportion d'œufs prédisposés à devenir ouvrières. De plus, ces jeunes reines ont socialement une influence négligeable sur l'élevage du couvain en comparaison des vieilles.
    Abstract: Sommario 1 Il seguito delle uova a 20° C dopo l'ibernazione di una reginaMyrmica rubra L. mostra le particolarità seguenti: a) l'andamento di produzione s'aumenta durante le tre prime settimane fino ad un massimo. Questo si tiene per 3–4 settimane, poi declina poco a poco fino a zero dopo 16 settimane; b) la grandezza delle uova declina durante il periodo quando l'andamento s'aumenta, poi rimane ad un valore costante minimo; c) le uova inclinate a divenire operaie sono fra loro fatte quando l'andamento s'avvicina al massimo e la grandezza s'avvicina al massimo e la grandezza s'avvicina al minimo. Altre uova, le prime grandi e le normali di puì tardi, entrano nella diapausa sotto le stesse condizioni di coltura. 2 Le regine possono dare o molte o poche uova inclinate a divenire operaie. I due tipi di regina possono trovarsi nella stessa colonia, o le colonie possono contenere soltanto uno tipo; le intermedie possono essere scarse. La differenza sembra doversi all' età, piochè le regine giovani fanno una grande proporzione di uova inclinate a divenire operaie. Di puì, queste regine hanno uno influenza sociale negligibile sull' allevamento della covata a petto delle regine vecchie.
    Notes: Summary 1 The egg sequence at 20° C after hibernation of a queenMyrmica rubra L. has the following peculiarities: a) rate of production rises during the first 3 weeks to a maximum that is held for 3–4 weeks and then declines gradually to zero after 16 weeks; b) egg size declines during the period of increasing rate but then stays at a steady minimum value; c) worker-biased eggs are amongst those laid when rate is approaching its maximum and size its minimum. Other eggs, both the large first ones and the normal later ones enter diapause under the same culture conditions. 2 Queens may either yield a lot of worker-biased eggs or very few. Both types of queen may occur in the same colony or colonies may have a single type, and intermediates may be rare. The difference appears to be due to age for young queens lay a very high proportion of worker-biased eggs. Moreover such queens have a negligible social influence on brood-rearing compared with old queens.

    Notes: Summary At first, the nests, belonging to differentBellicositermes, show a quite total identity. The large morphological likeness of the dwelling places limited by an idiotheca and surrounded by a «paraecie» is particularly significant. This likeness vanishes as the nests are growing bigger and bigger. To the development of the top height ofBellicositermes natalensis nests, is opposed the lateral developpement of theBellicositermes bellicosus nests. This lateral development is marked by the progressive desappearance of the «paraecie» as well as the idiotheca and the basement chamber. The dwelling place loses its individuality and divides into units more or less distinguisable.

    Notes: Summary The following is a study of resistance of worker honey bees (Apis mellifica L. var.ligustica) to high temperatures and of the effect of nutrition upon it. Survival of honey bees of spring generation was studied at 45, 50, 55 and 60°C during 15, 30, 45 and 60 minutes exposures. The survival rate was established at the end of their exposure, and 24 hours later. Lethal effects of heat were evident immediately after a 30 minute exposure to 50° C. These effects could be noticed in the survivers 24 hours following exposure. Effect of nutrition on heat resistance at 32° C and at 50° C was studied on one group of bees supplied with a 30 % honey solution; on another- with water only, and on a third group which served as a control (no food). Their survival at 32° C after 12 hours exposure was 100%, 81% and 48%, respectively. However, an exposure duration of 45 minutes at 50°C resulted in a survival of 22% of control bees as compared to a total survival of those fed on honey solution.

    Notes: Summary The genusPlebeia has a special significance for the study of social evolution of stingless bees: morphologically primitive, its species display a wealth of behavioural evolution, especially with respect to the oviposition process. We comparePlebeia remota with the few other members of the genus studied so far. Related to its subtropical geographical range, brood production is seasonal (there is no brood in the colony in colder months), and adult workers occur as summer and winter bees. The nest is in tree cavities, and the involucrum is absent or restricted to the winter period. Brood cells are arranged in horizontal combs, and new cells are built completely synchronously. Each series consists of up to 50 cells, their number being mainly dependent on colony size. Construction speed is remarkably constant, allowing 4–6 batches per 24 hours. Cell building and provisioning are activities of a small group of specialized workers. The oviposition cycle follows the classical subdivisions for stingless bees. During the patrolling phase a worker may “offer” a trophic egg in a most remarkable way: while retreating backward from the queen she bends the abdomen under thorax and head, and lays an egg on the comb. This egg is eaten by the queen or a worker. The provisioning, oviposition and operculation of all cells occur simultaneously, each cell is provisioned by 4–9 workers. Localization of a cell by the queen may be facilitated by its characteristic guard, which “defends” the cell against the approaching queen. The degree of synchronization within a batch is very high: the duration per cell lasts 420–950 sec, the batch of up till 50 cells needs only 557–1160 sec. Operculation is done by a worker that was not involved in the previous steps. Males are generally produced by the queen. Several male producing cycles per year occur. In orphan colonies laying workers give rise to males, and in queenright colonies workers may occasionally reproduce as well. Division of labour follows the general pattern for stingless bees; however, cell building and provisioning are activities of a specialized group of workers.

    Notes: Summary Queen rearing is suppressed in honey bees (Apis mellifera L.) by pheromones, particularly the queen's mandibular gland pheromone. In this study we compared this pheromonally-based inhibition between temperate and tropically-evolved honey bees. Colonies of European and Africanized bees were exposed to synthetic queen mandibular gland pheromone (QMP) for ten days following removal of resident queens, and their queen rearing responses were examined. Queen rearing was suppressed similarly in both European and Africanized honey bees with the addition of synthetic QMP, indicating that QMP acts on workers of both races in a comparable fashion. QMP completely suppressed queen cell production for two days, but by day six, cells containing queen larvae were present in all treated colonies, indicating that other signals play a role in the suppression of queen rearing. In queenless control colonies not treated with QMP, Africanized bees reared 30% fewer queens than Europeans, possibly due to racial differences in response to feedback from developing queens and/or their cells. Queen development rate was faster in Africanized colonies, or they selected older larvae to initiate cells, as only 1 % of queen cells were unsealed after 10 days compared with 12% unsealed cells in European colonies.

    Notes: Summary This is a first behavioural description of a large non-nest associated drone congregation of the stingless beeMelipona favosa. The about 400 drones had originated from different nests. The males interacted aggressively. Several gynes arrived at the drone congregation area (DCA). Olfactory stimuli triggered specific behaviours of the males as well as of the gynes but matings were not observed at the DCA.
