Early detection of hitchhiking pests requires the identification of strategic entry points via transport. Our INRAE team has developed a framework for achieving this in continental Europe for the Japanese beetle. Human-mediated dispersal ha...

#IPMPopillia
Pupils from class 2D had a good intuition! In fact, the Fungzuka device is being tested by CREA's researchers since summer 2023. The "Fungzuka" is an "Attract-Infest-Release" device that is conceived to bring adult Popillia japonica insects in c...

In recent months, the IPM Popillia Consortium has collaborated with SPOTTERON to create informational and dissemination materials about the invasive Japanese beetle (Popillia japonica), which has been spreading across Europe for several years. R...

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.
