Some viruses have been reported to attack belladonna. Belladonna mottle virus, which belongs to the turnip mosaic virus group, is spread by nematodes living in sandy soil (Rita & Animesh 2011). Slugs and garden snails have often been gathered off of Atropa belladonna plants. Larvae of the Chrysomelid beetle Epitrix atropae have been found on the roots of belladonna. The adults of this species have also been found feeding on the leaves. Caterpillars have occasionally been reported as living off of the plant as well. A. belladonna can also be harmed by Phytophthora erythroseptica, which has been found (in Scotland and Holland) to cause a root and crown disease. A large number of fungi (though mostly unidentified) have been observed in belladonna plants in America. One such fungus is the endophytic and pathogenic Diaporthe chailleti (Butcher 1947). Cercospora atropae, a type of leaf spot, is another parasitic fungus of A. belladonna (Butcher 1947).
