Abstract:
... A recombinant Autographa californica nucleopolyhedrovirus (AcMNPV) strain showing higher virulence against Trichoplusia ni larvae than the wild-type virus was developed. The 'enhancin' (VEF) gene of T. ni granulovirus (TnGV) and the AcMNPV polyhedrin gene were cloned into the baculovirus transfer vector pAcUW31. This plasmid and AcMNPV BacPAK6 DNA were co-transfected into the BTI-Tn5B1-4 cell line ...

Abstract:
... The total of 22 Baculovirus isolates surveyed in different corn producing regions in Brazil were used against fall armyworm, Spodoptera frugiperda (J.E. Smith). The viruses were purified and their suspensions were used to feed fall armyworm larvae from 4th and 5th instar. The mortality rate was checked daily and the infected larvae were frost after death, what generally occurred between the 5th an ...
