these caterpillars are slaughtering the plants ... 10 days ago the plants were healthy... just some white fly... I also treated them in advance with neem oil... but it does not seem to work with caterpillars...
pyrethrum?
no there is no light pollution. I can not understand what is due... the plant has been transplanted in the ground for about ten days, (before it was under neon t5, with a cycle of light equal to that outside)...maybe it just has to get used to the new environment, it shows some form of stress...
