ABSTRACT. This study examines accumulation dynamics of Cordyceps millitaris toxins in wax moth Galleria mellonella larvae after injection of fungal blastospores. At 3 and 4 days post infection average concentration of cordycepin was 244 ± 41 ng per 100 mg of dry mass of larvae. Accumulation of cordycepin was delayed one day in larvae, that were envenomated, by parasitoid Habrobracon hebetor (Say). Cordycepin concentration was correlated with hyphal bodies count in hemolymph, but only on tendency level (P > 0.07). The role of Cordyceps millitaris toxins in the development of mycoses was discussed.

KEY WORDS: Cordycepin, Cordyceps millitaris, Galleria mellonella, mycosis, fungal toxins.
