Patogenity Of Beauveria bassiana On Compost Media For Palm Oil Pest Control Oryctes rhinoceros L

Oryctes rhinoceros is an important pest of oil palm. This study aimed to obtain the best ability several compost organic materials containing B. bassiana for controlling O. larvae, in control various instars and concentration Beauveria O larvae. rhinoceros. Three stages research experiment were: 1) testing at 75 gl-1 concentration, using a completely randomized design (CRD), Experiment 2 test with 3 fungi media against 6 treatments 4 replications obtained 24 experimental units, while were 0 gl-1, 15 30 45 60 gl-1. Compost material contains fungus which has rhinoceros, namely OPEFB + sawdust because caused total mortality reach 90% conidia number 115.2 x108, initial death 67.2 hours after application, lethal time 50 206, application. can instar larvae up 92.5% 1, 2, have no effect on each instar. The used was 54-75 198-252 hours. had 87% early 54 times 213 hours, LC50 3.3% or equivalent 33
