- ... Mycophagy, though often overlooked, represents an interesting and unique ecological niche within the Coccinellidae. Facultative mycophagy has been reported from the aphidophagous Coccinellini and the polyphagous Tytthaspidini. Members of Halyziini, a cosmopolitan tribe of the Coccinellinae, are obligate mycophages specializing on the powdery mildew fungi of Erysiphales, a ubiquitous order infectin ...

- ... The adults and larvae of halyziine coccinellids (Coleoptera: Coccinellidae: Halyziini) are obligate mycophages on hyphae and conidia of powdery mildew (PM) (Erysiphales) fungi, that are plant pathogens warranting chemical control in many managed systems. These insects have been observed to reduce PM severity through consumption. Fungicide applications, however, may interfere with this ecological s ...
