KERAPATAN DAN VIABILITAS SPORA BEAUVERIA BASSIANA (BALS.) AKIBAT SUBKULTUR DAN PENGAYAAN MEDIA, SERTA VIRULENSINYA TERHADAP LARVA PLUTELLA XYLOSTELLA (LINN.)

Density and  viability of spores  of  Beauveria bassiana (Bals.) Vuill. due to sub-cultures and media enriched, and  its virulence against larvae of Plutella xylostella (Linn.) This laboratory research was conducted to determine density and  viability of spores of Beauveria bassiana due to sub-cultu...

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
