Monitoring
We thought it would be useful to update the list of P. japonica host plants. In this respect, the dataset deposited by Tayeh et al. (2023) serves two purposes: (1) to provide a list of the host plants of Popillia japonica via a comprehensive review o...

Regulatory reporting  of invasive alien species or controlled pests such as the Japanese beetle to national authorities can be challenging for citizens. Therefore, in the IPM Popillia Horizon 2020 project, the "Automated Reporting System" (ARS) ...

Europe is facing the first Japanese beetle outbreak north of the alps. The phytosanitary service of Zurich in Switzerland has detected Popillia japonica in monitoring traps and on herbs and shrubs in an area close to the airport of Zurich. The delimi...

Natural allies against Popillia japonica: Entomopathogenic fungi

Entomopathogenic fungi are micro-organisms naturally occurring in the environment, most of all in soil. They are natural parasites of insects that proliferate killing their host. Metarhizium is one of the most used ones in biological control.



The CREA team has isolated a Metarhizium robertsii strain called 17/T02 from the area infested by Popillia japonica in Italy for its effectiveness.





Now, we are preparing it to be tested as a biological control agent.



Fungal spores are stirred and mixed with alginate, kaolin and water.  





Drop by drop, we obtain small granules containing the fungal spores that we call SAPs (Sodium Alginate Pellets).




After air-drying, the SAPs are ready to be tested in field.
