Abstract
Eggs ofUtetheisa ornatrix proved equally vulnerable to fungal infection (Beauveria bassiana, Paecilomyces lilacinus) whether they contained parentally provided pyrrolizidine alkaloid (monocrotaline) or were free of such alkaloid. In in vitro tests, monocrotaline, either as free base or N-oxide, had no inhibiting effect on fungal cultures.
摘要
不论卵内是否含有亲代提供的吡咯里西啶生物碱（野百合碱），卵都同样容易受到真菌（球孢白僵菌、淡紫拟青霉）的感染。在体外试验中，游离碱或 N-氧化物形式的野百合碱对真菌培养均无抑制作用。
