The limited pollination efficiency of honeybees (Apidae; Apis) for certain crop plants and, more recently, their global decline fostered commercial development of further bee species to complement crop pollination in agricultural systems. In particular, a number of mason bees (Megachilidae; Osmia) are among the most widely used alternative pollinators, and their utilisation has been fine-tuned specifically for pollination in fruit tree orchards. A successful management system should not only aim at optimising pollination efficiency but also consider the relevant biological and ecological requirements to achieve sustainable and healthy bee populations. Here, we review the factors influencing the rate of population increase during the implementation of Osmia bees as orchard pollinators. These factors include nesting material, release methods, and control of antagonists as well as methods optimising management of developmental stages to synchronize bee activity with orchard bloom and to minimize developmental mortality.

ABSTRACT Pollinating insects provide a vital ecosystem service to crops and wild plants. Exposure to low doses of neonicotinoid insecticides has sub-lethal effects on social pollinators such as bumblebees and honeybees, disturbing their navigation and interfering with their development. Solitary Hymenoptera are also very important ecosystem service providers, but the sub-lethal effects of neonicotinoids have not yet been studied well in those animals. We analyzed the ability of walking Osmia to remember a feeding place in a small environment and found that Osmia remembers the feeding place well after 4 days of training. Uptake of field-realistic amounts of the neonicotinoid clothianidin (0.76 ng per bee) altered the animals9 sensory responses to the visual environment and interfered with the retrieval of navigational memory. We conclude that the neonicotinoid clothianidin compromises visual guidance and the use of navigational memory in the solitary bee Osmia cornuta .

Monzón; Jordi Bosch; Javier Retana;We studied the pollinating effectiveness of Osmia cornuta and Apis mellifera on 'Comice' pear. Osmia cornuta visited more flowers per minute (13.8) than A. mellifera (7.1-9.8). Both species visited similar numbers of flowers per tree (6.7-7.9), and switched rows with similar frequency (4.0-7.9%). Rate of stigma contact was 98.7% for O. cornuta, 51.8% for A. mellifera pollen-nectar foragers, and 19.0% for A. mellifera nectar foragers. Fruit-set in flowers visited once was 28.9, 29.3, and 12.9%, respectively. Seed- set was similar (7-8 seeds per fruit) in all three types of flowers. Osmia cornuta females provisioned their nests with 94.4% pear pollen. Stepwise multiple regression showed that fruitlet-set across the orchard was mostly related to tree size (trees with fewer flowers set more fruit per flower) (β = -0.64; P <0 .001), whereas seed-set at harvest was best explained by O. cornuta (β = 0.47; P < 0.005) and A. mellifera (β = 0.35; P < 0.05) spatial distribution.

Six polymorphic microsatellite loci were used for a first population structure survey including 9 continental European and one island population. Observed levels of genetic variability and heterozygosity proved to be moderate. There was no significant differentiation among continental O. rufa populations. Only the island population from Cyprus was clearly separated. A correlation between geographical and genetic distance indicates gene flow among continental bees. The relatively high homogeneity in O. rufa is probably caused by low effective population size rather than an imprint of past population events. All microsatellites amplified in three further Osmia species.

The amount of ROS can be additionally increased by environmental factors. This study investigates the ability of red mason bees (Osmia bicornis L.) to inactivate free radicals during insect development. Both male and female bees were studied, from the larval to the active imago stage. The activity of four antioxidant enzymes, superoxide dismutase, catalase, peroxidase and glutathione S-transferase, was measured; and glutathione content and total antioxidant status were determined. The highest values of the examined parameters were found in feeding stages-in larvae and in active imagines of both genders. Significant differences between genders were noted mainly in catalase activity, which was lower in overwintering imagines and active females than in males. Most differences were observed between females and males after emergence.

Nevertheless, misoriented cocoons appear in nature in notable proportions. A detailed analysis of sex, space available for cocoon spinning, cocoon size, and nest diameter in the red mason bee (Osmia bicornis) showed that smaller males are more prone to misorientation than larger females. Generally, smaller individuals of both sexes are more often misoriented because smaller larvae disregard the direction of the entrance during cocoon construction. Moreover, cocoons in stems of smaller diameter are less often misoriented than bees in wider nests. Our results suggest that cocoon size and available space are the most important traits affecting cocoon orientation.

description Publicationkeyboard_double_arrow_right Article 2014 France EnglishHAL CCSD James H. Cane;James H. Cane;International audience; Flowers with poricidally dehiscent anthers are typically nectarless but are avidly visited and often solely pollinated by bees that sonicate the flowers to harvest pollen. Sonication results from shivering the thoracic flight muscles. Honey bees (Apis) and the 4,000+ species of Megachilidae are enigmatic in their seeming inability to sonicate flowers. The oligolectic megachilid bee Osmia brevis was found audibly sonicating two of its beardtongue pollen hosts, Penstemon radicosus and P. cyananthus. The bees’ high-pitched sonication sequences are readily distinguishable from flight sounds in audiospectrograms, as well as sounds that result from anther rasping. Instead, floral sonication by O. brevis resembles the familiar sounds of bumblebees buzzing, in this case while visiting P. strictus flowers.

We investigated the impact of three fluctuating and three constant temperature regimes on prepupal weight, mortality, and development time of Osmia bicornis. Prepupal weight decreased with increasing temperature, but not as strong under fluctuating conditions. Adult mortality increased in the warm treatments. Fluctuating (versus constant) temperatures accelerated development in the most stages and temperature regimes. The duration of almost all developmental phases decreased with increasing temperature, except for the prepupal phase that was prolonged in the warm treatments. The differences in thermal responses to fluctuating vs. constant temperatures illustrated the importance of fluctuating temperatures in studies investigating potential consequences of climate change for insects, including pollinators.

In 2018, many females of a captive population were observed collecting pulp from drupelets of both unripe and ripe red raspberries (Rubus idaeus) despite available foliage from this plant as well as five weedy forbs. Females capped 122 nests with raspberry pulp, the material that they used for their nests’ cell partitions as well. Such red nest plugs were never produced by the preceding ten captive generations of this bee (about 3000 nests), even when caged with raspberries. Raspberry fruit pulp proved to be of intermediate preference for nest construction among alternative foliar choices offered to nesting females.

Dormann;Bernd Gruber; Katharina Eckel; Jeroen Everaars; Carsten F. Dormann;International audience; A worldwide decline of pollinator abundance is recorded and the worldwide pollination of insect-pollinated crops has traditionally depended on a single species, the honeybee. The risks of relying on a single species are obvious. Other species have been developed for particular crops. Here we present an extension of the framework of Bosch and Kemp (2002) that deals on how to develop a bee species into a crop pollinator. We used nesting aids in different settings to address five important issues that are necessary for an effective management of a bee species in a commercial setting. Our study system was the red mason bee (Osmia bicornis) in apple orchards in eastern Germany, but our approach should be transferable to other settings. The first issue was to demonstrate that it is possible to increase population size of O. bicornis by providing nesting aids. Second, we present how someone can study landscape features that promote the occurrence and abundance of O. bicornis. Further, we studied the dispersal of the species inside the orchard, and could demonstrate that bees prefer to disperse along lines of trees. Finally, we studied the effect of nesting substrate and type of farming on the recruitment of bees. We found a close relationship between the length of nesting tubes and achieved sex ratio and a negative effect of conventional farming on the number of nests built. We conclude with recommendations on how our findings can be used to optimize the management of O. bicornis in apple orchards.

Des nids places dans la nature ont permis de capturer des populations en debut de printemps; puis les larves ont ete laissees a temperature ambiante au laboratoire pour achever leur developpement. L'hiver, les adultes dans leur cocon ont ete conserves a 4°C en chambre froide. Le printemps suivant ils ont ete places dans des nichoirs pourvus de tubes de papier de diametre et de longueur varies et les nichoirs ont ete installes dans les vergers d'amandiers. La periode d'emergence des abeilles a dure 9 j en 1989 et 15 j en 1990. La mortalite due a l'hivernage a ete faible (4,21%) en 1987 mais elevee (18,54%) en 1990

description Publicationkeyboard_double_arrow_right Article 2004 FranceSpringer Science and Business Media LLC Jordi Bosch; William P. Kemp;Jordi Bosch; William P. Kemp;Osmia cornuta adults require exposure to wintering temperatures followed by incubation in the spring to emerge. We studied winter survival, weight loss, emergence time, and post-emergence longevity in O. cornuta exposed to a variety of pre-wintering and wintering treatments. Few bees emerged after exposure to wintering durations <30 days. Maximum survival and longevity were obtained with wintering durations of 90-150 days. Time to emergence following incubation declined with increasing wintering duration and increasing wintering temperature. Pre-wintering treatment had a dramatic effect on bee fitness. Bees pre-wintered for 15 days lost less weight, had higher survival and lived longer than bees pre-wintered for 45 or 75 days. In general, larger bees were more likely to survive the winter and lived longer than smaller bees. We discuss the relevance of these results to survival in wild O. cornuta populations and the management of populations used in orchard pollination.

description Publicationkeyboard_double_arrow_right Article 2019 FranceSpringer Science and Business Media LLC Maxime Eeraerts; Matti Pisman; Ruben Vanderhaegen; Ivan Meeus; Guy Smagghe;International audience; Effects of pesticides have been debated as one of the causes of worldwide declines of bee populations. Improving the risk assessment of pesticides on bees is important to halt these declines. Pesticide risk assessment today mainly focuses on one bee species, the honey bee. Because of differences in life cycles among bee species, this risk assessment needs to be adapted to take these differences into account. For both the adult and larval life stages, development of test protocols for solitary bees is required. Here, we summarize the current knowledge on larval tier 1 tests based on the first test protocols for solitary bee larvae available in the literature. As the ecology and rearing of solitary bees of the genus Osmia spp. are well known, we propose this genus as a model species in a first step to develop protocols for solitary species. In addition, we discuss guidelines, relevant endpoints, and research needs for the development of a standardized oral toxicity test protocol of solitary bee larvae.

description Publicationkeyboard_double_arrow_right Article 2015 France EnglishHAL CCSD Karsten Seidelmann; Adrienne Bienasch; Franziska Pröhl;Karsten Seidelmann; Adrienne Bienasch; Franziska Pröhl;International audience; Recent declines of bee populations have led to great interest in preserving bee species and fuel efforts to develop solitary species for pollination purposes. Xylophilous solitary bees can be easily reared in artificial nests tubes for commercial agricultural as well as wild plant pollination. The impact of the dimensions of these artificial nest tubes on reproduction parameters was studied in the red mason bee, Osmia bicornis (L.), in a long-term study. Increasing tube diameter positively affected both progeny sex ratio and body size. Sex ratio, but not progeny body mass, was negatively affected by short tube length. Building costs rose with increasing diameter accompanied by deteriorated efficiency of tube space utilization. Although female bees used a wide spectrum of nest dimensions, artificial nest tubes of 8–10 mm internal diameter and a length of at least 150 mm were optimal.

description Publicationkeyboard_double_arrow_right Article 1999 France EnglishHAL CCSD Karsten Seidelmann;Karsten Seidelmann;Nests of the stem- or hole-nesting megachilid bee, Osmia rufa, were analysed to help clar- ify the function of the outermost empty chamber of the nest, the vestibulum. Only nests in an exposed nesting environment had a long vestibulum, whereas nests protected from sun and temperature fluc- tuations (within a honey bee hive body) had short vestibuli or none at all. The rate of parasitism of the first cell from nests with a vestibulum did not differ from nests without a vestibulum in both nesting environments. The short vestibulum built by O. rufa in protected nests probably represents the remaining space of a nest hole that is too short for an additional cell. Nests in exposed environments suffered much higher mortality in all brood cells owing to parasites attacking open cells during nest construction. Additionally, mortality caused by the cleptoparasitic drosophilid, Cacoxenus indaga- tor, one of the main parasites of the Red Mason bee, increased greatly from the rear to the entrance of nests. When nesting bees detect the cleptoparasitic fly, they do not provision the outermost space of nesting holes, thus constructing a vestibulum, to avoid misinvestment due to the high risk of par- asitism. In nests exposed to normal weather factors, vestibular cells probably shelter the brood also from high fluctuating temperatures. © Inra/DIB/AGIB/Elsevier, Paris

La synchronisation de l'emergence des adultes avec la floraison de la culture cible est essentielle pour utiliser au mieux le potentiel pollinisateur de cette abeille solitaire, principalement lorsque les floraisons sont courtes. Dans cette etude, des cocons mâles et femelles d'O. cornuta ont ete places dans des recipients en verre et exposes a differents regimes de temperatures d'hivernage et a diverses modalites d'incubation. Les abeilles qui ont partiellement ou totalement hiverne dans un entrepot d'une region de vergers d'amandiers ont emerge sur une periode beaucoup plus longue (fig 1) que celles qui avaient hiverne dans des refrigerateurs (figs 2 a 5)
