Abstract
The susceptibility of third-instar Spodoptera exempta (Walk.) to a heat-treated nuclear polyhedrosis virus was tested in the laboratory. The polyhedral suspension was purified by differential centrifugation and heat-treated at temperatures that ranged from 20 to 90°C for 10–30 min. The LT50 ranged from 108.4 hr for virus heated at 50°C (10 min) to 162.2 hr for virus heated at 80°C (10 min). The fiducial limits to the LD50s were calculated at 0.95 probability.
