Occurrence of entomopathogenic fungi on phylloplanes in Tilia x europaea crowns between 1 and 13 m was assessed in urban parks. Prevalence of fungal infections in ladybirds (Coleoptera: Coccinellidae) collected from Tilia x europaea was assessed to determine whether fungi found on phylloplanes also occurred as infections in ladybirds. Isaria spp. was most abundant on phylloplanes (mean colony forming units (CFU) per leaf +/- SE, 0.33 +/- 0.03) followed by Beauveria spp. (0.22 +/- 0.02 CFU per leaf) and Lecanicillium spp. (0.19 +/- 0.02 CFU per leaf). Densities of inoculum were higher in inner crowns and decreased with height, although Lecanicillium spp. peaked at 5-7 m. Upper phylloplane surfaces harboured higher densities of Isaria spp. and Beauveria spp. than lower surfaces, whereas Lecanicillium spp. was equally distributed. Most prevalent on ladybirds were Isaria spp. (20.6% Harmonia axyridis; 4.8% natives), Lecanicillium spp. (13.6% H. axyridis; 4.8% natives), with fewer Beauveria spp. infections (2.6% H. axyridis). Molecular identification revealed Beauveria bassiana, B. pseudobassiana, Isaria farinosa and Lecanicillium muscarium among isolates of both tree and ladybird origin. Tilia x europaea phylloplanes support a diverse assemblage of entomopathogenic fungal species with a different prevalence in coccinellids compared to their relative abundance in this habitat.Leaves of urban trees harbour entomopathogenic fungi up to 13 m in tree crowns and act as a reservoir of fungal infection in invasive alien and native ladybirds.Leaves of urban trees harbour entomopathogenic fungi up to 13 m in tree crowns and act as a reservoir of fungal infection in invasive alien and native ladybirds.
