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...

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...

Developmental Stage Photos of the Japanese Beetle from Our Laboratory

We are beyond excited to share developmental stage photos of the Japanese beetle (Popillia japonica) directly from our laboratory experiment. 

The Japanese beetle undergoes three larval stages, which means that the larvae do not grow steadily but develop three times until they pupate and finally emerge as adult beetles. We have also included a video showing moving larvae and pupae.

However, differentiating larvae from the Japanese beetle of other beetle species poses a challenge. We look forward to delving into more details on this topic in an upcoming blog post.

And if you are interested in further insights, an infographic on the complete life cycle of the Japanese beetle can be found in this blog:


See you soon, and stay tuned for more updates!
