Alates of the Formosan subterranean termite (FST), Coptotermes formosanus Shiraki, collected after swarming in 2002 died within 48 hrs, and the cadavers were visibly infected with a fungus. Fungi were picked from the cadavers, transferred to media and ultimately isolated to purity. A single fungal isolate, C4-B, taxonomically identified as Metarhizium anisopliae (Metschnikoff), was found to cause rapid mortality of FST alates. This is the first report of a biological control agent for termite alates. Strain C4-B was more lethal to both alates and workers when compared to M. anisopliae strain ESC1, marketed as the termite biocontrol agent BioBlast®. 100% of FST alates exposed to C4-B spores (106 spores / μl) were killed in 3 days. Field studies where C4-B spores were dispersed on grassy lawns resulted in 100% mortality of alates by day 5.
