Infection patterns of Harmonia axyridis (Coleoptera: Coccinellidae) by ectoparasitic microfungi and endosymbiotic bacteria
Original language description
The invasive alien ladybird Harmonia axyridis (Coleoptera: Coccinellidae) hosts a wide range of natural enemies. Many observations have been done in nature but experimental studies of interactions of multiple enemies on Ha. axyridis are rare. In light of this knowledge gap, we tested whether the host phenotype and presence of bacterial endosymbionts Spiroplasma and Wolbachia affected parasitism of Ha. axyridis by the ectoparasitic fungus Hesperomyces harmoniae (Ascomycota: Laboulbeniales). We collected 379 Ha. axyridis in the Czech Republic, processed specimens, including screening for He. harmoniae and a molecular assessment for bacteria, and calculated fecundity and hatchability of females. We found that high hatchability rate (71 %) was conditioned by high fecundity (20 eggs daily or more). The average parasite prevalence of He. harmoniae was 53 %, while the infection rate of Spiroplasma was 73 % in ladybirds that survived in winter conditions. Wolbachia was only present in 2 % of the analyzed ladybirds. Infection by either He. harmoniae or Spiroplasma did not differ among host color morphs. In the novemdecimsignata morph, younger individuals (with orange elytra) were more heavily parasitized compared to old ones (with red elytra). Fecundity and hatchability rate of females were unaffected by infection with either He. harmoniae or Spiroplasma. However, female ladybirds co-infected with He. harmoniae and Spiroplasma had a significantly lower fecundity and hatchability compared to females with only one or no symbiont.
