... littoralis multiple nucleopolyhedrovirus (SpliMNPV) against beet army worm, Spodoptera exigua(Hübner) under harsh sunny field conditions in Saudi Arabia. A preliminary test of SpliMNPV was performed to determine the lethal concentrations of this virus against the first and second larval instar of S. exigua. The potency of ten plant extracts as UV absorbers were done by measuring the absorption spectra of the 0.5% extracts ...

...ates of S. litura nucleopolyhedroviruses (SltNPV) were collected from infected larvae fed on natural cotton crops. The NPV was isolated from the larvae and viral occlusion bodies (VOBs) were detected using a light microscope. The toxicity of native isolates against S. litura also studied by testing different concentrations (1 x 102 POB (Polyhedral occlusion bodies) mL-1- 1 x 1010 POB mL-1) from the occl...

...ses of Spodoptera litura nucleopolyhedrovirus (Pakistan isolate SpltNPV-Pak-BNG). Infected larvae with final polyhedrosis (disease resulting in dissolution of larval tissues and accumulation of viral occlusion bodies) exhibited reduced food intake and weight gain relative to uninfected larvae. The unexposed larvae and the larvae that were exposed but survived exhibited the same food consumption and weight gain. This study did thus not reveal any sub-lethal eff...

...n the same host multiple nucleopolyhedroviruses (MNPVs) Spli MNPV, and granulovirus SpliGV. Mixed infection of the tow viruses was carried out in vivo and in vitro, showing clearly that the mixture with Spli GV enhance the effect of Spli NPV when it was introduced 24hr prior to NPV or simultaneously: In addition to' protein profiles by SDS-PAGE, TEM electron microscopy ultrathin sections and hybridization dot blots, gel transfer to follow the probable mechanis...
