Historically, research on the effects of PPP on bees has focused on the honey bee (Apis mellifera), while non-Apis bee species remain largely understudied. This study is intended as a first step to address this obvious knowledge gap and hope that it may be used to facilitate the development and implementation of a scientifically sound wild bee risk assessment with limited additional testing needs. We have compiled a comparative data set on bee sensitivity (acute contact exposure) against acetylcholine esterase (AChE) inhibitors, pyrethroids, neonicotinoids, organochlorides and bee bodyweight, a trait likely influencing bee sensitivity to PPP exposure. In total, we collected sensitivity data for up to 24 bee Hazards of pesticides to bees 14th international symposium of the ICP-PR Bee protection group, October 23 – 25 2019, Bern (Switzerland) Abstracts: Oral Presentation 58 Julius-Kühn-Archiv, 465, 2020 species per insecticide group covering five of seven bee families. Using this information, while controlling for their phylogenetic non-independence, we build inter-species correlation models to predict bee sensitivity to PPPs belonging to different modes of action based on their bodyweight. We find that 1) bee weight is a robust predictor of bee resilience against insecticide exposure in many cases and 2) Apis is a particularly sensitive bee genus especially when body weight is taken into account. In contrast the currently proposed non-Apis surrogate species (Bombus terrestris and Osmia sp.) for European risk assessment as well as many stingless bee species, are comparatively resilient to many classes of insecticides. We discuss the consequences of these findings in the context of the global non-Apis risk assessment debate in Europe and the Americas.","PeriodicalId":30493,"journal":{"name":"JuliusKuhnArchiv","volume":"1 1","pages":"57-58"},"PeriodicalIF":0.0,"publicationDate":"2020-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45611383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The latter come in contact or enter in bees during nectar and pollen collection and transferred inside the beehives. In addition, residual prevalence in honey, and beebread also reflects the chemical treatments that take place inside the beehives in order to mainly control the parasitic mite of Varroa destructor. In this context, during the period of 2014-2018, 109 samples of honey, pollen, and beebread (63 honey and 46 pollen and beebread), including samples originated also from colonies in which honeybees’ death incidents were recorded, were sent by authorities and individuals in Benaki Phytopathological Institute for the determination of pesticides and their transformation products. More than 130 analytes were investigated by applying two multi-residue methods (an HPLC-ESI-MS/MS and a GC-MS/MS), based on modified QuEChERS methodology using for clean-up Z-Sep, PSA, and C18 materials. In particular, the two analytical methods applied were validated according to the SANTE/11945/2015 and 11813/2017 guidelines. More specifically, the recoveries observed for the majority of the analytes ranged between 68 and 117%, while the relative standard deviations were below 19%. The calculated limits of quantification (LOQs) ranged from 1 to 10 ng/g depending on the analyte. Other parameters, such as linearity, selectivity, precision and matrix effect were also validated. Until the end of 2018, 37 determinations were registered in honey, resulting in a 38% of positive to at least one active substance in honey samples (16 active substances and transformation products were detected in total). The detected concentrations of pesticides and their transformation products ranged between 1.3 and 785 ng/g honey. In some cases, maximum residue limits (MRLs) violations were evidenced. Coumaphos, imidacloprid, acetamiprid, the transformation products of amitraz, DMF-DMPF, tau-fluvalinate and in limited cases metabolites of imidacloprid and coumaphos (its oxon metabolite), were the most predominant compounds detected in honey, while several pyrethroids such as λ-cyhalothrin, cypermethrin, and cyfluthrin were also found. In several honey samples, more than one active substance was detected, while the most common combination comprised of coumaphos, imidacloprid, and DMF. In pollen, and beebread more active substances were identified (21) with a comparative number of determinations (including a higher number of fungicides detected compared to honey), and a higher proportion of positive samples (65%). Overall, this work aims to provide an overview of the current situation of pesticides and transformation products occurrence in honey, pollen, and beebread during the period of 2014-2018 in Greece. 3.3 Impact of the use of plant protection products harmful to bees on bee colonies during spring: Results of a monitoring programme in apple o","PeriodicalId":30493,"journal":{"name":"JuliusKuhnArchiv","volume":"1 1","pages":"63-63"},"PeriodicalIF":0.0,"publicationDate":"2020-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46238513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the time the EFSA GD was finalized, no data on honey bee larvae were available due to absence of suitable methods. That is why in 2013 the European Crop Protection Association (ECPA) perfomed an impact analysis of the new EFSA risk assessment, using extrapolated endpoints derived from acute oral honey bee endpoints. Today, a number of honey bee larvae toxicity studies (138 active substances or formulated products) have been conducted according to the newly developed testing methods for single exposure (OECD TG 237) repeated exposure studies until the end of the larval development (D7/D8) and repeated exposure testing (OECD GD 239) until adult hatch (D22). These experimental data have been used to determine the ‘pass rates’ for 215 worst case uses (72 fungicide spray and solid uses, 91 herbicide spray uses, incl. 8 PGR uses and in total 52 insecticide spray and solid uses, incl. 2 nematicide and 3 IGR uses) according to the EFSA Bee GD and to compare with the original ECPA impact analysis. As standardized test methods for non- Apis bees larvae were not available, risk assessment according to EFSA for bumblebees and solitary bees based on the honey bee endpoint as surrogate corrected by a safety factor of 10. Morevoer, the sensitivity of the NOEDs at D8 and D22 in repeated exposure (D 22) studies were analysed. \u0000Overall, the toxicity of fungicides and herbicides to honey bee larvae (expressed as means and medians of NOED and LD50 values) was moderate to low, while insecticides as expected displayed stronger toxicity. Moreover, the endpoints for herbicides were on average a factor of 2 higher than fungicides which ranges within the normal biological variability (factor of 3). In addition, it is unclear, if the difference is related to a slightly higher toxicity or other factors like different physical chemical properties (e.g. lower solubility). For insecticides, toxicity was about 125 (based on medians) and 6 to 8 (based on means) times higher than herbicides. In the screening risk assessment according to EFSA Bee GD the majority of fungicide (83.3%) and herbicide (95.6%) uses passed the risk assessment for larvae; whereas, for all insecticide uses thr pass rate was about 29%. In the Tier 1 risk assessment, these pass rates slightly increased and were even higher in the ‘treated crop’ and ‘weed in the field’ scenarios for fungicide and herbicide uses, almost being 100%. Pass rates for insecticide uses did not improve very much and amounted to be about 42% for both scenarios. When basing the risk assessment of bumblebee and solitary bee larvae on 1/10th of the honey bee larval endpoint, the majority of active substances and their respective products will fail the screening (overall about 96%) and Tier 1 risk assessment (overall about 90%). \u0000Alternative risk assessment approaches proposed by ECPA (e","PeriodicalId":30493,"journal":{"name":"JuliusKuhnArchiv","volume":"1 1","pages":"82-89"},"PeriodicalIF":0.0,"publicationDate":"2020-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43365460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
