Severe pod rot of cacao, Theobroma cacao, was observed at Chichijima, Bonin Islands, in May, 2005. The causal fungus was identified as Lasiodiplodia theobromae (Pat.) Griffon and Maubl. based on the morphological characteristics, inoculation experiments, and molecular phylogenetic analysis. Among the four tropical fruits cultivated in the Ogasawara Islands, cacao isolate showed clear pathogenicity on banana, mango and papaya fruits but not on passion fruit. This is the first report of Lasiodiplodia pod rot (kajitsufuhai-byo in Japanese) on cacao pods caused by L. theobromae in Japan.
