“…The pest was also found in Sardinia in Italy in 2021, in Switzerland in 2017, and in Germany in 2021 (EPPO, 2017;EPPO 2022a;EPPO, 2022b). Currently the pest is considered officially present in Portugal, Italy and Switzerland (EPPO, 2023b) Furthermore, P. japonica has been detected in India in the Wayanad district of the Kerala region (Smitha et al, 2017) and in the Tamil Nadu and Karnataka regions (GBIF, 2023).…”

Popillia japonica is a priority pest which all EU countries must survey annually. However, surveys are not required if the climate in the country is unsuitable for the pest. In previous research, it was unclear whether the climate in Finland was suitable for P. japonica.Based on a literature review, we identified soil moisture and temperature as critical factors for the establishment of P. japonica. The suitability of soil moisture for P. japonica in Finland was assessed by comparing the summer rainfall across Finland to the corresponding rainfall within the known range of the pest. The suitability of the winter soil temperature was assessed by comparing the winter soil temperature across Finland with the minimum temperatures that P. japonica has been reported to endure. The suitability of summer soil temperatures was assessed by comparing the annual growing degree days (GDD) across Finland with a the annual GDD which P. japonica has, in previous assessments, been considered to require to complete its life cycle (i.e., 711 above 10 °C).The results indicate that the soil moisture and winter soil temperature are suitable for P. japonica throughout Finland. However, the summers appear to be too cool for the pest throughout the country since the threshold GDD was not reached every year anywhere, and even in the warmest areas, it was reached only in 75% of the years.The greatest sources of uncertainty in the assessment are the uncertainty of the annual GDD that P. japonica needs to complete its life cycle and the lack of research on the pest's cold tolerance.

Viral Infection Control in the Essential Oil-Bearing Rose Nursery: Collection Maintenance and Monitoring

et al. 2022

Viral diseases affecting the essential oil rose, which is a valuable object of agricultural production, may have a significant negative impact on the economic value of this crop. Hence, the study and control of potentially dangerous viruses is essential to improving the quality of cultivars of this raw plant material, to enable production of valuable derivatives. The diversity of viruses affecting Rosa L. plants manifests itself in their conditional division into those that are specific to this crop, and those that are hosted by other plants. Representatives of both groups are found in different countries, however, a low number of viruses identified have been thoroughly studied through the use of experimental methods. In particular, with regard to many viruses, the issue of their spread remains open. The viruses infecting Rosa L. plants along with other crops are described in the literature in detail, as the range of hosts they affect is rather wide and well-studied. It is also possible to single out the three most significant viruses affecting this host—Prunus necrotic ringspot virus, Apple mosaic virus and Arabis mosaic virus which individually, or collectively, cause viral diseases that manifest themselves in mosaic symptoms. The most likely mechanisms for the spread of the Rosa L. species viruses are vegetative propagation procedures and transmission by various pests. These presumptions underlie viral infection control methods, including a well-thought-out planting scheme and provision of accurate plant care, which considers plant disinfection, disease monitoring associated with diagnostics and obtaining virus-free material through biotechnology techniques.
