Interpretive Summary: The harlequin ladybird has been introduced in many countries for biological control of agricultural pests. It is now found on four continents outside of its native Asian range and it is considered an invasive alien species (IAS). Despite a large body of work on the invasion ecology of this invasive ladybird, the mechanisms driving its invasive capabilities and how it interacts with natural enemies remains unknown. Parasites play an important role in regulating populations of their hosts. This study presents a review of the parasites (a nematode and ectoparasitic fungus and mite) of the harlequin ladybird, discussing their distributions and effects on host populations across the host’s native and invasive range.

Technical Abstract: The harlequin ladybird Harmonia axyridis (Coleoptera: Coccinellidae) has been introduced widely for biological control of agricultural pests. Populations of H. axyridis have established in four continents outside of its native range in Asia and it is considered an invasive alien species (IAS). Despite a large body of work on invasion ecology, establishment mechanisms of IAS and their interactions with natural enemies remain open questions. Parasites, defined as multicellular organisms that do not directly kill the host, play an important role in regulating host populations. This study presents a review of the parasites of H. axyridis, discussing their distributions and effects on host populations across the host’s native and invasive range. These parasites are: Hesperomyces virescens Thaxt. fungi, Coccipolipus hippodamiae (McDaniel and Morrill) mites, and Parasitylenchus bifurcatus Poinar and Steenberg nematodes.
