The gememic body, NatLUX-CGC-7W, was used, which provides 5000µW/s, ie 5mJ/ s.

This energy was applied for 60s on a beetle from the Coleoptera family, ie it was subjected to an energy of 300mJ, in 4 installments, at an interval of 10min.

The first dose didn’t bother him. Only after the second dose did he begin to hide from the UV-C light, and after the fourth dose he seemed to be more upset.

Other researchers say:

If the eggs of these beetles are subjected to ultraviolet radiation (254nm), it was found that no adults appeared after irradiation with UV-C light for 16-24min.
