Light-induced fruit body formation of an entomogenous fungus Paecilomyces tenuipes

Abstract

Asexual fruit body formation of an entomogenous fungus, Paecilomyces tenuipes, on an artificial culture medium was investigated. For the fruit body induction, light/dark condition was important. Illumination by white light in a particular critical period preceded by a dark period induced the fruit bodies. The critical period was identified to be around 6–14 d after inoculation at 20°C
