As such, they hold a vast potential to help shed light on the extent and interdependencies of factors influencing the decline in the number of insects. However, to date this potential has not yet been fully leveraged, as the production of reliable data requires large-scale study designs, which are very labour intensive and therefore costly. \u0000A novel Artificial Intelligence (AI) based visual monitoring system could enable the partial automatization of data collection on activity, forager loss and impairment of the central nervous system. The possibility to extract features from image data could prospectively also allow an assessment of pollen intake and a differentiation of dead bees, drones and worker bees as well as other insects such as wasps or hornets. \u0000The technology was validated in different studies with regards to its scalability and its ability to extract motion and feature related information. \u0000The prospective possibilities were analyzed regarding their potential to enable advances both within ecotoxicological research and the monitoring of pollinator habitats.","PeriodicalId":30493,"journal":{"name":"JuliusKuhnArchiv","volume":"1 1","pages":"124-129"},"PeriodicalIF":0.0,"publicationDate":"2020-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46827362","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}

In a similar way, wax and royal jelly can also be collected. Guttation fluid can be sampled directly from certain crops, which requires careful consideration of the crop irrigation and climatic conditions for guttation production (and usually some very early mornings!). Soil cores can be sampled to inform on likely exposure to ground-dwelling bee species, and/or the potential for systemic residues in succeeding crops. Future work With the combined expertise of Staphyt’s Bee Team, consisting of regulatory, scientific and field specialists, together we can provide both practical (field) and regulatory (consultancy) support on the conduct of pan-European field and tunnel residue studies for environmental and consumer risk assessments. In the coming seasons, we will continue to explore the following open questions: Does the confinement of bees to a tunnel impact bee behaviour and are residues therefore still comparable to realistic field scenarios? Is it possible to respect the intended interval time between applications if a surrogate crop is used? Can the sampling methods be adapted to improve collection efficiency? i.e. to reduce the resources (manual time and cost) required, and increase the quantities of each matrix available for subsequent residue analysis? 3.5.P Establishment of honeybee brood studies under semi-field conditions in Korea Kyongmi Chon1*, Hwan Lee1, Bo-Seun Kim1, Yeon-Ki Park1, Are-Sun You1, Jin-A Oh2, Yong-Soo Choi3 1Chemical Safety division, Department of Agro-food Safety and Crop Protection, National Institute of Agricultural Sciences, Rural Development Administration, Wanju, Korea; 2Agromaterial Assessment division, Department of Agro-food Safety and Crop Protection, National Institute of Agricultural Sciences, Rural Development Administration, Wanju, Korea 3Sericulture and Apiculture Division, Department of Agricultural Biology, National Institute of Agricultural Sciences, Rural Development Administration, Wanju, Korea E-Mail: kmchon6939@korea.kr DOI 10.5073/jka.2020.465.049","PeriodicalId":30493,"journal":{"name":"JuliusKuhnArchiv","volume":"1 1","pages":"107-107"},"PeriodicalIF":0.0,"publicationDate":"2020-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42888650","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}

In general, bees can be exposed to PPPs directly by contact spray application (overspray) or indirectly via nectar and pollen. The leafcutter bees additionally can be exposed to (possibly) contaminated leaf pieces which are used for the building of brood cells. Therefore, contact toxicity might be of major importance within leafcutter bee species. \u0000Acute contact toxicity tests with M. rotundata based on the existing honey bee testing guideline OECD No. 214 were carried out, to make a first step in the direction of the development of a standard test method and collect data for the comparison of inter- and intra-species contact toxicity sensitivity. The toxic reference substance dimethoate was used as test substance. LD50/24h values of M. rotundata were compared to values of A.mellifera generated in a similar period of time. \u0000The low mortality observed in the control also after 96 hours, confirms the feasibility and reliability of the test method. The LD50/24h values of M. rotundata in all four tests were higher compared to those of A. mellifera. Accordingly, M. rotundata appeared to be slightly less sensitive to formulated dimethoate than A. mellifera.","PeriodicalId":30493,"journal":{"name":"JuliusKuhnArchiv","volume":"1 1","pages":"109-113"},"PeriodicalIF":0.0,"publicationDate":"2020-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48022353","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 P. tanacetifolia crop was grown in soil treated with the predicted 20-year plateau concentration of chlorantraniliprole in the top 20 cm of soil (equivalent to a predicted 20-year plateau concentration of 0.088 mg a.s./kg). Additionally, two chlorantraniliprole applications at 60 g a.s./ha were made in the chlorantraniliprole treatments (T1 and T2). In T1 both applications took place before P. tanacetifolia flowering at BBCH 51-55 and BBCH 55-59. In T2 one application was conducted before P. tanacetifolia flowering at BBCH 55-59 and one application during P. tanacetifolia flowering and during daily bee flight at BBCH 61-62. The application in the control (C) and reference item treatment (R) (400 g dimethoate a.s./ha) was carried out during full P. tanacetifolia flowering and bumble bee flight. The bumble bee colonies were exposed to the treated flowering P. tanacetifolia crop for 20 days in the tunnels and afterwards the colonies were kept on a monitoring site. The results of this study indicate no significant differences between the chlorantraniliprole treatment groups T1 and T2 and the control regarding all parameters assessed (i.e. mortality in the colonies and in the tunnels, flight activity at the hive entrance, hive weight development, condition of the colonies and production of young queens and males). Overall, no effects of chlorantraniliprole on bumble bee B. terrestris colonies including queen/male production, adult and larval survival and forager flight activity were found.","PeriodicalId":30493,"journal":{"name":"JuliusKuhnArchiv","volume":"1 1","pages":"113-121"},"PeriodicalIF":0.0,"publicationDate":"2020-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45376748","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}
