“…This makes red mason bees good candidates for model species, e.g. in studies of pesticide toxicity, the effect of environmental pollution, ecological stoichiometry, or interspecific interactions (Fliszkiewicz et al 2012a;Szentgyörgyi et al 2017;Kierat et al 2018;Sgolastra et al 2019;Filipiak 2019;Eeraerts et al 2020). Females fly throughout the spring until early summer.…”

Red mason bee (Osmia bicornis) thermal preferences for nest sites and their effects on offspring survival

Ectotherms usually require a narrow range of thermal conditions for development; thus, parental selection of oviposition sites is crucial. In a field experiment, we investigated female solitary red mason bee (Osmia bicornis) preferences for potential nest site temperatures and their effects on offspring development. The results showed that bees detected and avoided nest sites with high temperatures (28°C) and often chose cooler (24°C) or ambient temperatures (average 18–20°C). This is a protective behaviour because offspring survival decreases with increasing nest temperature, mostly due to mortality at the egg stage. Elevated temperatures also led to weight loss in adult bees. However, hot nest temperatures appeared to deter adults or kill parasite larvae, as the highest numbers of parasites were observed in unheated nests. We concluded that choosing the proper temperature for nests is an important element in bee life strategies, especially in warming environments.

“…There is an ongoing international movement to develop solitary bee-specific methodologies for evaluating the effects of acute and chronic pesticide exposure. Compiling available publications on solitary bee larval testing, Eeraerts and colleagues contend that the Osmia genus should serve as the model for developing specific toxicity test protocols for solitary bees [ 104 ]. As a result, current efforts to build testing methods are centered on commercially available Osmia species and have led to the development of an acute contact testing method for solitary bees [ 105 ].…”

Background Pollination services provided by solitary bees, the largest group of bees worldwide, are critical to the vitality of ecosystems and agricultural systems alike. Disconcertingly, bee populations are in decline, and while no single causative factor has been identified, pesticides are believed to play a role in downward population trends. The effects of pesticides on solitary bee species have not been previously systematically cataloged and reviewed. Objectives This systematic scoping review examines available evidence for effects of pesticide exposure on solitary bees to identify data gaps and priority research needs. Methods A systematic literature search strategy was developed to identify and document reports on solitary bee pesticide exposure-effects investigations. Literature was subsequently screened for relevance using a Population, Exposures, Comparators, and Outcomes (PECO) statement and organized into a systematic evidence map. Investigations were organized by effect category (lethal effects on immatures, lethal effects on adults, sublethal effects on immatures, and sublethal effects on adults), species, pesticide class, and publication year. Results A comprehensive literature search of Web of Science and ProQuest Agricultural & Environmental Science supplemented by targeted internet searching and reference mining yielded 176 reports and publications for title and abstract screening and 65 that met PECO criteria (22 included lethal and 43 included sublethal effects endpoints). Relevant design details (pesticide, test compound configuration, study type, species, sex, exposure duration) were extracted into literature inventory tables to reveal the extent endpoints have been investigated and areas in need of additional research. Conclusions Evidence mapping revealed diversity in the pesticides and endpoints studied across the database. However, dilution across bee species, lack of complementary laboratory work and paucity of replicated investigations complicate efforts to interpret and apply available data to support pesticide risk assessment.

“…In addition, it will be necessary to expand this approach beyond acute contact scenarios to incorporate acute oral exposure and chronic as well as developmental pathways. For many of these routes, test system for non‐ Apis bees are being developed (Eeraerts et al 2020), which in turn will enable exploratory testing of a wider range of bee species. Currently, there is only limited information (Arena and Sgolastra 2014; Spurgeon et al 2016; Thompson 2016), but once a critical amount of data are available, the sensitivity scaling relationships and association with body weight should be compared to the acute contact scenarios to see if it is possible to generalize these results.…”

Extrapolating Acute Contact Bee Sensitivity to Insecticides Based on Body Weight Using a Phylogenetically Informed Interspecies Scaling Framework

Plant protection products, including insecticides, are important for global food production but can have adverse effects on nontarget organisms including bees. Historically, research investigating such effects has focused mainly on the honeybee (Apis mellifera), whereas less information is available for non-Apis bees. Consequently, a comprehensive hazard (sensitivity) assessment for the majority of bees is lacking, which in turn hinders accurate risk characterization and consequently bee protection. Interspecies sensitivity extrapolation based on body weight might be a way to improve the situation, but in the past such approaches often ignored the phylogenetic background of the species used, which in turn potentially reduces the robustness of such results. Published acute contact sensitivity data (median lethal dose per bee) of bees to insecticides, their body weight, and their phylogenetic background were used to build interspecies scaling models to predict bee sensitivity based on their weight. The results indicate that 1) bee body weight is a predictor of acute contact bee sensitivity to a range of insecticides, and 2) phylogeny (nonindependence of data points) needs to be considered in cross-species analysis, although it does not always confound the observed effects.
