The Applications Flour Formulation Beauveria bassiana Balls (Vuill.) Local Entomopathogen Fungi with Bran Flour Carrier against Oryctes rhinoceros L. Larvae in the Laboratory

The entomopathogenic fungi B. bassiana local is an effective biological agent to control pests among of them Oryctes rhinoceros. O. rhinoceros is a pest of palm oil plantation in Indonesia which causing any problem therefore need to control. Increases the mortality level of entomopathogenic fungi B. bassiana local can be done by forming a better formulation, for example flour formulation with the addition of bran flour as a carrier. Bran flour can encourage the entomopathogenic fungi B. bassiana to germinate faster and produce a higher number of conidia so that it can control O. rhinoceros larvae more quickly. This research was conducted using a completely randomized design (CRD) consisting of 5 treatments and 4 replications obtained 20 experimental units each infested ten O. rhinoceros larvae in star 3. The treatment is additional bran flour into 30 g B. bassiana starter made into flour formulation. Additional some of level bran flour to one kilogram empty fruit bunch (EFB) were 0 g. kg - 1 EFB, 0.45 g. kg - 1 EFB, 0.6 g. kg - 1 EFB, 0.75 g. kg - 1 EFB, and 0.9 g. kg - 1 EFB. The result showed of this research B. bassiana flour formulation and additional bran flour 0.90 g. kg - 1 EFB causing total mortality of O. rhinoceros larvae increasing starter from is 77, 50% becomes flour formulation 82, 5%.
