Larvae of the fall armyworm annually cause damage to most of the warm-season turfgrasses. Terminal stolons of common bermudagrass were dipped in the appropriate dilutions of BioCide-TRF™ (Mycotrol GH-ES) Beauveria bassiana (2.0 X 1013 conidia/qt), and placed on two water-saturated filter papers (for constant humidity) in each feeding chamber in the lab. Three randomly selected 5-d-old larvae were introduced into each 9-cm-diam. x 15-mm-deep plastic feeding chambers labeled for the respective treatment in a RCB design with 7 reps. Silwet (0.04%) was added to each treatment as a wetting agent to ensure good coverage. Treatments were observed daily for mortality.
