| Abstract: | AcNPV (Autographa californica nucleopolyhedrovirus), P1NPV (Prodenia litura nucleopolyhedrovirus) and Bt (Bacillus thuringiensis) preparation were mixed together in certain proportion, to make a NPV compound used for biocontrol. The results of virulence test showed that the synergism of this mixture were 5. 1 and 9. 5 times as many as those of AcNPV and P1NPV along to Autographa califounica and Prodenia litura correspondingly. This NPV compound was propagated in the larvae of beet army-worm Spodoptera exigua (Hiibner) as its host and formed the primary products SBN-3. The results of this NPV compound in field tests showed that the mortalities of 5. exigua, P. litura and Hellula undalis Fabricius were more than 90% ?and those of Plutel-la xylostella L. and Artogeia rapae (L. ) attained to 80% -85%. |
