Abstract
Aim of study: Thrips in raspberry crops are receiving attention in Scandinavian raspberry production because of the increasing sighting of their presence in the flowers. Specific information on thrips species occurring in raspberry and their damage potential is scarce, making thrips management challenging. Therefore, this study aimed to identify thrips in the flowers of cultivated raspberry, Rubus idaeus L., in South Norway. Area of study: Sogndal, Luster and Frogn, Southern Norway Material and methods: Adult thrips were sampled from eight commercial raspberry orchards in the counties Vestland and Viken in June-July 2022. Thrips were mounted using Hoyer’s medium and a total of 213 specimens were morphologically identified. Main results: Five species of thrips were found, Thrips fuscipennis Haliday, Thrips major Uzel, Thrips flavus Schrank, Thrips vulgatissimus Haliday and Thrips brevicornis Priesner. Most specimens were T. flavus, followed by T. fuscipennis and T. vulgatissimus. Research highlights: Among the five species found, only T. fuscipennis has previously been reported in cultivated raspberry, but all five species are associated with flowers of many plants. The findings imply a larger and more geographically varied thrips fauna on raspberry than currently documented. This should be taken into account in future studies on thrips management in raspberry.

Nordic agriculture faces big challenges to reduce phosphorus (P) loss from land to water for improving surface water quality. While understanding the processes controlling P loss and seeking for P mitigation measures, Norwegian and Swedish researchers have substantially benefited from and been inspired by Dr. Andrew Sharpley’s career-long, high-standard P research. Here, we demonstrate how Sharpley and his research have helped theNordic researchers to understand the role of cover crops in cold environmental conditions, best manure P management practices, and ditch processes. His work on critical source area (CSA) identification and site assessment tool development have also greatly inspired our thinking on the targeting of mitigation measures and the contextualizing tools for Nordic climate, landscape, and soils.While reflecting on Sharpley’s legacy, we identify several needs for Norwegian and Swedish P research and management. These include (1) tackling the challenges caused by local/regional unevenness in livestock density and related manure management and farm P surpluses, (2) identifying CSAs of P loss with high erosion risk and high P surplus, (3) obtaining more high-resolution mapping of soils with low P sorption capacity both in the topsoil and subsoil, (4) improving cross-scale understanding of processes and mitigation measures and proper follow-up of applied mitigation measures, and (5) increasing collaborations of researchers with farmers and farmers’ advisory groups and watershed groups by developing high-quality educational courses and extension materials. The needs should be addressed in the context of the challenges and opportunities created by climate change.
