“…For this, a pollen trap with a grating of round holes and 10% of efficiency (Louveaux, 1958) was fixed to the hive entrance. The trap was active three times during April, twice during May, June, July, and August, and once during September.…”

“…Plants need honey bees as pollinator agents to perpetuate the plant species, and honey bees need plants to obtain the necessary nutrients for the bees' development, nectar and pollen. Multiple factors influence this relationship, including honey bee biology and characteristics of the plants species from which they obtains his food (Louveaux, 1958;von Frisch, 1969;Bolchi-Serini & Salvi, 1986;Fewell & Wiston, 1996;Armesto, 1998;de Sá-Otero et al, 2004). Honey bees visit some plants surrounding the beehive to obtain pollen and nectar, while others plants are not visited.…”

“…Foragers are also in contact with pollen while making and carrying pellets back to the hive (Louveaux, 1958). Therefore, a topical exposure of foragers to contaminated pollen cannot be excluded, though it is difficult to estimate.…”

Modes of honeybees exposure to systemic insecticides: estimated amounts of contaminated pollen and nectar consumed by different categories of bees

et al. 2005

-The hazard posed to honeybees by systemic insecticides is determined by toxicity tests that are designed to study the effects of insecticides applied on the aerial parts of plants, but are not adapted to systemic substances used as soil or seed treatments. Based on the available data found in the literature, this paper proposes modes of honeybees exposure to systemic insecticides by estimating their pollen and nectar consumption. Estimates are given for larvae and for the categories of adults which consume the highest amounts ofpollen, the nurse bees, and -nectar, the wax-producing bees, the brood attending bees, the winter bees, and the foraging bees. As a case study, we illustrate these estimates with the example of imidacloprid because its concentrations in sunflower nectar and in sunflower and maize pollens of seed-dressed plants have been precisely determined, and because its levels of lethal, sublethal, acute, and chronic toxicities have been extensively investigated.Apis mellifera / systemic insecticide / exposure / imidacloprid / nectar / pollen

“…C'est le cas des graminées et des arbres à chatons. Une étude portant sur plusieurs années et un très grand nombre d'observations (Louveaux, 1958 permet de dégager les grandes lignes suivantes. Sur les 4 000 à 4 500 espèces de phanérogames que compte la flore de France on a pu en recenser 436 qui jouent avec certitude un rôle dans l'alimentation des abeilles domestiques.…”

“…En pétiode de grande abondance de floraisons, en avril, mai et juin dans le bassin parisien, la teneur en azote est la plus forte. Au début du printemps et en été, alors que les floraisons sont plus rares, les choix possibles sont plus restreints ; la teneur en azote total est plus hasse (Louveaux, 1958).…”

Résumé.-Dans les relations entre les abeilles et les plantes la récolte du pollen constitue l'élément essentiel. Elle est étudiée du point de vue quant~atif et du point de vue qualitatif. Les choix opérés par les abeilles au sein d'une flore sont sous la dépendance de stimuli sensoriels ainsi que de facteurs trophiques et de facteurs génétiques. L'étude du comportement de récolte du pollen est liée à celle de la pollinisation. L'abeille est utilisable comme indicateur biologique par l'intermédiaire des pollens qu'elle récolte.L'analyse pollinique des miels est une méthode utilisable par la recherche fondamentale. Elle sert également à des contrôles de qualité et d'origine dans l'agroalimentaire. Des efforts restent à faire pour adapter ses techniques à ses divers objectifs.Summary.-Among the relations between bees and plants pollen collection is the most important feature and is studied from a quant~ative and also qualitative point of view. The choices made by bees among a flora depends on sensorial stimuli, trophic factors and also genetic factors. Study of pollen collection behaviour is connected with pollination. The honey bee is su~able as biological indicator through the pollen she gathers. Pollen analysis of honey is a suitable method for fundamental research but is also used for quality and origin contrais in food industry. Efforts have ta be made ta adapt ils technical processes to ils various purposes.
