Uji Mortalitas Kumbang Beras (Sitophilus oryzae) Dengan Pengendalian Hayati Jamur Beauveria bassiana

Abstract

Research on mortality test of rice beetle (Sitophilus oryzae) with the biological control of the fungus Beauveria basianna. The purpose of the research was to analyze the mortality ability of S. oryzae against B.basianna which was carried out from March to April 2021 at the Microbiology and Biotechnology Laboratory, Faculty of Science and Technology PGRI Palembang university. The study used RAL, namely the administration of B.basianna with different concentrations consisting of 5 treatments and 4 replications, namely P0 (as control), P1 (konidia cfu/ml), P2 (konidia cfu/ml), P3 (konidia cfu/ml), P4 (konidia cfu/ml), P5 (konidia cfu/ml). The results showed that there was an effect of treatment concentration on S.oryzae mortality. Treatment P5 (konidia cfu/ml) resulted in the highest mortality percentage with an average of 28.75%.
