Torrubiella luteorostrata: a pathogen of scale insects and its association with Paecilomyces cinnamomeus with a note on Torrubiella tenuis

Torrubiella luteorostrata and Paecilomyces cinnamomeus are reported for the first time from Thailand. Field observation and cultural study has linked P. cinnamomeus with T. luteorostrata. The Torrubiella state appears during the rainy season while the Paecilomyces anamorph occurs at the beginning and end of the wet season. The fungus does not appear during the hot, dry season. Torrubiella tenuis is also reported for the first time from Thailand but it was not possible to link this to an anamorph.
