Production of geraniol by honey bees of various ages National Institute of Agronomic Research
Boch, R.; Shearer, D.A..
The amount of geraniol obtained by a standard procedure from the Nassanoff gland of the honey bee varied from zero to 1·5 μg per bee, depending on the age of the bees. Newly emerged bees had no geraniol. Guard bees produced ca. 0·3 μg per bee and a marked increase to ca. 1·0 μg per bee occurred when the bees began to forage.

Rare sexual reproduction events in the clonal reproduction system of introduced populations of the little fire ant Inra
Foucaud, J.; Jourdan, H.; Le Breton, J.; Loiseau, A.; Konghouleux, D.; Estoup, A..
A unique reproductive system has previously been described in Wasmannia auropunctata, a widespread invasive ant species, where males are produced clonally, female queens are parthenogens, and female workers are produced sexually. However, these findings were mostly based on samples originating from only a limited part of the native range of the species in South America. We used microsatellite markers to uncover the reproductive modes displayed by a large number of nests collected in various invasive W. auropunctata populations introduced 40 years ago into New Caledonia, where the species now forms a single 450-km-long supercolony. Although the main reproduction system in New Caledonia remained clonality for both male and female reproductives, we found...

Regulation of oviposition in social hymenoptera National Institute of Agronomic Research
Brian, M.V.; Brian, A.D..
The rate of increase of population in societies of social insects obviously depends upon the numbers of adults which can be produced per head of the adult population. Ideally, the numbers of eggs laid should be just appropriate to this situation, so that the prevailing food supply may be efficiently transformed.

Reinpaarungs-prüfung an einer honigbienensippe bekannter quantitativer merkmale National Institute of Agronomic Research
Goetze, G..
Drones had been selected for special features of their wing structure. Afterwards they were mated, by means of artificial insemination, with queen carrying similar wing features. The line "Trifolium", bred by this method, showed several characteristics with little variability. Eighteen offspring-queens of this line were placed in a mating-yard, which had no other colonies in a circle of 5.6km diameters, with carefully selected drones. Using the wing-structure as criterion one was able to demonstrate that only queens (15%) had mated with the desired drones, while the remaining queens had mated with drones of unknown origin. In an inbred-line it also might be possible to draw conclusions about the inherance of proboscis-lengh on the basis of...

Residual fumagillin activity in sugar syrup stored by wintering honeybee colonies National Institute of Agronomic Research
Furgala, B..
Experiments are described which show that the level of Nosema infection was satisfactorily reduced by feeling colonies in October with Fumidil B (but not with Nosemack). Other experiments show that syrup containing fumagillin, fed to colonies in the fall and overwintered in the colony, was effective the following summer in reducing the level of Nosema infection in caged bees.

Respiration rates of larvae of drone and worker honey bees, Apis mellifera L. National Institute of Agronomic Research
Allen, M. Delia.
The oxygen consumptions of drone and worker honey bee larvae were determined at 32. over the period between hatching 1Ind the sealing of the cells prior to pupation. A decrease in respiration rates with increasing age was found in both drone and worker larvae when the rates were calculated 011 a unit weight basis, but in both castes the oxygen consumption per larva rose rapidly in the period following hatching, subsequently increasing less rapidly. Drone larvae consumed greater amounts of oxygen than worker larvae of the same weight, and this was apparently linked with their more rapid increase in weight.

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....

Septicaemia disease of the honeybee in Victoria National Institute of Agronomic Research
Langridge, D.F..
An outbreak of a septicaemic condition of bees occurred in East Gippsland, Victoria, during the autumn, winter, and spring of 1958. The condition appears to conform generally with cases of septicaemia recorded in Canada, United States, and France. A causative organism has been isolated from septicaemic bees in Victoria which appears to fall into the type of the Pseudomonas species of Landerkin and Katznelson (1959). This organism has been proved pathogenic to bees when inoculated by dipping or injection.

Sex and clonality in the little fire ant Inra
Foucaud, J.; Fournier, D.; Orivel, J.; Delabie, J.H.C.; Loiseau, A.; Le Breton, J.; Kergoat, G.; Estoup, A..
Reproduction systems are controlling the creation of new genetic variants as well as how natural selection can operate on these variants. Therefore, they had historically been one of the main foci of evolutionary biology studies. The little fire ant, Wasmannia auropunctata, has been found to display an extraordinary reproduction system, in which both males and female queens are produced clonally. So far, native sexual populations of W. auropunctata have not been identified. Our goals were to identify such sexual populations and investigate the origins of female parthenogenesis and male clonality. Using mitochondrial DNA and microsatellite markers in 17 native populations, we found that traditional sexual populations occurred in W. auropunctata and are...

Social immunity in honeybees (Apis mellifera): transcriptome analysis of varroa-hygienic behaviour Inra
Le Conte, Y.; ALAUX, C.; Martin, J.F.; Harbo, J.R.; Harris, J.W.; Dantec, C.; Séverac, D.; Cros-Arteil, S.; Navajas Navarro, M..
Honeybees have evolved a social immunity consisting of the cooperation of individuals to decrease disease in the hive. We identified a set of genes involved in this social immunity by analysing the brain transcriptome of highly varroa-hygienic bees, who efficiently detect and remove brood infected with the Varroa destructor mite. The function of these candidate genes does not seem to support a higher olfactory sensitivity in hygienic bees, as previously hypothesized. However, comparing their genomic profile with those from other behaviours suggests a link with brood care and the highly varroa-hygienic Africanized honeybees. These results represent a firststep toward the identification of genes involved in social immunity and thus provide first insights...

Studies in the mode of action of royal jelly in honeybee development : III. The effect of experimental variation in diet on growth and metabolism of honeybee larvae National Institute of Agronomic Research
Dixon, S.E.; Shuel, R.W..
Norms were established for respiration, growth, and tissue composition of 0- to 72-hour-old female honeybee larvae reared in the laboratory on natural royal jelly and worker jelly diets. The worker jelly diet was then altered experimentally in the direction of royal jelly through additions of sugar and certain water-soluble acids of unknown structure extracted from royal jelly, but present in the natural diets of larvae of both female castes. In general, developmental norms were shifted in the direction of the norms of larvae fed royal jelly, but the changes were not fully co-ordinated. The added acids were strongly growth inhibitory. A high inverse association between the total water-soluble acid content of the diet and larval weight suggested that the...
