Laboratory studies were performed to determine the insecticidal activity of baculovirus against diamondback moth, Plutella xylostella . The nucleopolyhedrosis (HaNPV) was tested against 2 nd instar larvae fed on cabbage leaf disks treated with aqueous suspensions of occlusion bodies (OB). Lethal concentrations values (LC 25 , LC 50 , and LC 75 ) were 2.2 × 10 3 , 3.8 × 10 4 , and 6.6 × 10 5 PIB/ml for 2 nd larval instars, respectively. Median lethal time (LT 50 ) to similar response levels (mortality rates 50-75%) decreased with decreasing larval age (from 114.23 to 106.05 h). Larval development time and pupal weight were not affected by different concentrations (LC 25 , LC 50 , and LC 75 ) of HaNPV. Significant differences were found in the pupal rate and adult emergence in larvae treated by different concentrations. In conclusion, HaNPV treatment failed to cause high mortality rates in P. xylostella larvae, but it had prompt deleterious effects on survivor's development and emergence.
