An Egyptian isolate of  Spodoptera littoralis  nucleopolyhedrovirus ( Spli NPV) was tested for its potential as biocontrol agent in comparison to  Autographa californica  multiple nucleopolyhedrovirus ( Ac MNPV). Comparative assays of  Spli NPV and  Ac MNPV against 2 nd  instar larvae of  Spodoptera littoralis  revealed 4-fold greater susceptibility of  S. littoralis  to  Ac MNPV than to  Spli NPV based on LC 50  values for the two viruses. The LT 50 s determined for  Spli NPV and  Ac MNPV using LC 50  of the virus against 2 nd  instar larvae were 4.2 and 5.8 days, respectively. A DNA segment of 405 bp containing highly conserved region from polyhedrin gene of  Spli NPV ( Polh-cr ) was successfully amplified by PCR. Subsequently, this DNA segment was cloned and sequenced. Nucleotide sequence and its deduced amino acid sequence were compared to all available sequences in GenBank. Sequence alignment results revealed that  Polh-cr  showed significant similarities with 91 different baculovirus isolates. The percentage of homology ranged from 78% for  Plusia orichalcea  NPV to 99% for  Spli NPV. This highly conserved region provides a candidate that could be used in easy, fast and economic prospective systems for virus detection as well as in biological control strategies.
