Bumble bees show asymmetrical discrimination between two odors in a classical conditioning procedure Inra
Laloi, D.; Pham-Delègue, M.H..
Olfactory processing of two odorants and their mixture was investigated in bumble bees Bombus terrestris using classical conditioning of the proboscis extension. In a standard procedure, workers were able to learn linalool, phenylacetaldehyde, and the mixture of these two components, with a similar level of response to these three stimuli. Thereafter, when we applied a differential conditioning procedure where one rewarded odorant was presented alternately against an unrewarded one, an asymmetrical discrimination between the two pure odors was found. Bumble bees performed well in the discriminative task when linalool was the rewarded stimulus and phenylacetaldehyde the unrewarded one, but they had difficulty learning phenylacetaldehyde if it was the...

Effect of the queen on worker reproduction and new queen production in the bumble bee Bombus terrestris Inra
Lopez-Vaamonde, C.; Brown, R.M.; Lucas, E.R.; Pereboom, J.J.M.; Jordan, W.C.; Bourke, A.F.G..
We tested the hypotheses that a non-volatile pheromone inhibiting worker egg-laying and queen development produced by Bombus terrestris queens has effects transferable (a) from workers to other workers or larvae, or (b) on wax. We subdivided small, young colonies with a single mesh screen (Experiment 1) and larger, older colonies with a double mesh screen (Experiment 2). One treatment (in both experiments) involved the transfer of workers, and one treatment (in Experiment 2 only) involved the transfer of wax, from the queenright to the queenless compartments. Queenlessness induced significantly earlier onset of worker aggression (followed by egg-laying) in all treatments in both experiments, and significantly earlier queen production in all treatments in...

Nutritive value of 15 single pollens and pollen mixes tested on larvae produced by bumblebee workers (Bombus terrestris, Hymenoptera : Apidae) Inra
Tasei, J.N.; Aupinel, P..
Laboratory trials were performed at 27 °C on micro-colonies comprised of three Bombus terrestris workers. They were fed with syrup and pollen paste ad libitum. The micro-colonies were terminated on the 14th day after egg-laying. Two bioassays tested the nutritive value of 6 pure pollens and 9 commercial pollen mixes on bumblebee larvae. Among 10 criteria tested, the most sensitive to the different pollens were the mean weight of larvae and the rate of discarded larvae. Differentiation between treatments was easier with single pollens that ranged from 14.4% to 24.9% crude protein for Helianthus and Castanea respectively, than with mixes that ranged from 12.9% to 17.6%. The best performance ranking was assigned to Castanea, Papaver and Rubus, which produced...

Patch departure rules in Bumblebees: evidence of a decremental motivational mechanism Inra
Lefebvre, D.; Pierre, J.; Outreman, Y.; Pierre, J.S..
The patch living rules of a pollinator, the bumblebee Bombus terrestris L., are studied here in the framework of motivational models widely used for parasitoids: The rewarding events found during the foraging process are supposed to increase or decrease suddenly the tendency of the insect to stay in the current patch and therefore to adjust the patch residence time to the patch profitability. The foraging behaviour of these pollinators was observed in two environment types to determine their patch-leaving decisions. The rich environment was composed of male-fertile flowers, offering pollen and nectar, and the poor one of male-sterile flowers, offering little nectar and no pollen. The experimental design consisted of a patch system in which inflorescences...

The Composition of Beeswax and Other Waxes Secreted by Insects National Institute of Agronomic Research
Tulloch, A.P..
This review deals with waxes of members of two quite different groups of insects the bees and the scale insects,which secrete large amounts of wax. The former use wax as a structural material and the latter as a protective material. The compositions of waxes from some of these insects are described and particular attention is paid to the compositions of the unhydrolyzed waxes and to the presence of hydroxy acids. New analyses of beeswax and of wax of a species of bumble bee are reported. The structures of the diesters, hydroxyesters and diols of beeswax are elucidated. The bumble bee wax contains major proportions of saturated and unsaturated hydrocarbons, and of long chain saturated, mono- and diunsaturated esters. The relationship between structure and...
