The natural occurrence of Pandora heteropterae (Zygomycetes: Entomophthorales) infecting Lygus lineolaris (Hemiptera: Miridae).
An unknown fungal pathogen was recovered from Lygus lineolaris (Palisot de Beauvois) during a survey of parasitic and pathogenic natural enemies conducted in Franklin County, Arkansas. The pathogen was identified as Pandora heteropterae (Bałazy) Keller based on characteristics of the morphology, as well as growth and sporulation on hosts. The fungus infected 11 of the 3405 (0.32%) wild L. lineolaris collected. In a laboratory host-range bioassay, five of seven hemipteran species from the families Miridae, Coreidae, Lygaeidae, and Pentatomidae were successfully infected. P. heteropterae was previously reported only once, from an unidentified host species in Poland. Here we describe the morphology and growth of P. heteropterae and discuss its potential impact on L. lineolaris in the field.
