Abstract
En 中文
• A comparative analysis of He. harmoniae parasitism across three ladybird species under identical laboratory conditions. • Harmonia axyridis shows 100% parasite prevalence and high parasite density, P. quatuordecimpunctata displays moderate parasite prevalence with low density, and C. montrouzieri shows low fungal prevalence with no mature thallus development. • The position of thalli on the host cuticle varies by host: mainly pronotum and elytra on Ha. axyridis, mostly thorax on P. quatuordecimpunctata, and restricted to compound eyes on C. montrouzieri. • Hesperomyces harmoniae has promising prospects as a biological control agent against the invasive alien ladybird Ha. axyridis.
