Komparasi Enzim Kitinase dari Beauveria bassiana galur Lokal Sulawesi Selatan Terhadap Mortalitas Ulat Grayak (Spodoptera litura)

Edit
Abstract: This  study  aims  to  determine  the  enzyme  activity  of  chitinase  B. bassiana  strain  found  in  South Sulawesi. Knowing the relationship between the activity of chitinase enzyme isolate-isolate B.bassiana strain in South Sulawesi with mortality grayak caterpillar (Spodoptera litura). This descriptive research by linking the  enzyme  activity  of  chitinase  from  Beauveria  bassiana  strain  local  South  Sulawesi  on  mortality  grayak caterpillar larvae (Spodoptera litura). Based on the research that has been done shows that the activity of the enzyme from South Sulawesi B.bassiana local strains showed differences in each isolate, isolates the origin Enrekang 7.15 units / ml, isolate origin Bantaeng 7.12 units / ml, 6.32 units of isolate origin Pinrang / mi and isolate  the  origin  of  Maros  6.2  units  /  ml.  There  is  a  relationship  between  enzyme  activity  with  mortality rates  of  larvae  of  Spodoptera  litura. The  highest  mortality  is  caused  by  the  isolate  origin  Enrekang  86%, followed  by  the  isolate  origin  Bantaeng  83%,  76%  Pinrang  origin  isolates  and  isolate  the  origin  of  Maros 73%.
