Until 2020, scientists from a German Institute of Biology discovered that this white substance would actually grow in a petri dish. That means it’s not a discharge. So what exactly is it? research doesn’t stop 　　Through scanning electron microscope observation and gene sequencing, scientists discovered that this layer of white substance was actually a plant pathogen – Fusarium oxysporum (a white filamentous fungus). Although the fungus can be detected throughout the tortoise beetle’s life cycle, the scientists focused on the…
