B. bassiana was grown in Saborroud Dextrose Broth (SDB) cultures enriched with cricket powder. The results showed that the best sub-culture was the fourth sub-culture enriched with cricket powder, producing 6.05 x 108 spores/ml with 30.7% viability. The highest larval mortality was found in the second sub-culture enriched with cricket powder which was reach 78.33%. The spore density and viability, and virulence of B. bassiana grown in sub-culture without cricket powder enrichment was consistently decreasing from the second sub-culture to the eighth. Sub-cultures enriched with cricket powder could increase density, viability, and virulence of B. bassiana in every sub-culture. Overall, the enrichment with cricket powder up to 0.5% could increase the density, viability, and virulence of B. bassiana.http://jhpttropika.fp.unila.ac.id/index.php/jhpttropika/article/view/131sub-cultures, Beauveria bassiana, Plutella xylostella |
