Agricultural landscape affects sex-specific differences in the abundance of Drosophila suzukii in raspberry orchards
Maarten De Groot, Magda Rak Cizej, Andreja Kavčič, Špela Modic, Franček Poličnik, Nina Šramel, Primož Žigon, Jaka Razinger, 2022

Povzetek: In recent decades, the spotted wing Drosophila (SWD) (Drosophila suzukii), an invasive pest, has caused a great deal of damage to fruit crops. There is therefore an urgent need to develop strategies to control the populations of this species. It has been found that the landscape context can buffer or increase the severity of pest outbreaks in agriculture, and it is important to understand how this process works in SWD for all crops. Given this background, we investigated the influence of forest on SWD populations in raspberry orchards and surrounding agricultural land. We selected 10 locations in the central part of Slovenia, five of which were closer than 200 m from the forest edge and five of which were more than 200 m from the forest edge. We collected SWD adults in three habitat types per location from the end of June until the end of October 2020. The results showed that forest harboured a larger SWD population than orchards and agricultural land. Over the season, the number of individuals increased exponentially over time, and the difference between forest and other habitat types increased. The distance from the forest had a negative effect on the abundance of SWD. There was a difference in abundance observed between males and females, with males being less abundant farther away from the forest than females. However, the distance from the forest only had a negative effect on the abundance of females in September. Based on the results, we propose potential measures for the control of SWD in raspberry orchards.

Genetic aspects linked to production and use of forest reproductive material (FRM) : collecting scientific evidence for developing guidelines and decision support tools for effective FRM management
Dušan Gömöry, Katri Himanen, Mari Mette Tollefsrud, Claes Uggla, Hojka Kraigher, Sandor Bordacs, Paraskevi Alizoti, Stuart A'Hara, Aline Frank, Gunnar Friis Proschowsky, Josef Frýdl, Thomas Geburek, Monique Guibert, Mladen Ivanković, Ana Jurše, Stuart Kennedy, Jan Kowalczyk, Heike Liesebach, Tiit Maaten, Andrej Pilipović, Roberta Proietti, Volker Schneck, Alain Servais, Brynjar Skúlason, Christoph Sperisen, Frank Wolter, Tefide Yüksel, Michele Bozzano, 2021

Povzetek: This report summarises the current state of knowledge in genetic aspects linked to the production and use of forest reproductive material (FRM). The first chapter describes the different categories of FRM, considers the strategic choice between artificial and natural regeneration in the face of climate change, and articulates the need for and purposes of FRM. Chapter 2 outlines the FRM production chain, in terms of: i) FRM approval, management, collection and certification (seed sources, stands, orchards, plus trees and clones others); ii) Testing standards and examples; iii) Effect of seed and seedling material not intended for use as FRM on forest genetic resources; iv) Breeding effects on basic material including conservation strategy; v) Harvesting, processing and storage of seeds; vi) Nursery practices; vii) Certification and Traceability; and viii) FRM Trading and Transport. Chapter 3 examines FRM with regard to: i) Forest regeneration strategies % especially considering climate change, and ii) Assisted migration and available decision support tools. Chapter 4 provides a detailed overview of forest establishment methods, and chapter 5 looks at keeping records of seed origin to improve forest management. The final chapter offers 38 recommendations arising from the review. This work is the result of an international collaboration rooted in EUFORGEN for more than two decades. It is built on the firm belief that the genetic element is decisive for the creation of a resilient forest capable of surviving threats and adapting to changes, thus enabling the evolution of ecosystems and the conservation of the productive landscape.
