Evaluasi Bahan Carrier Dalam Pemanfaatan Jamur Entomopatogen, Beauveria Bassiana (BALSAMO) Vuillemin Untuk Mengendalikan Hama Penggerek Bonggol Pisang, Cosmopolites Sordidus GERMAR

Abstract

. Hasyim, A. 2006. Evaluation of carrier materials for Beauveria bassiana (Balsamo) Vuillemin to control banana corm borer, Cosmopolites sordidus GERMAR. The experiment was conducted at Entomological Laboratory, Indonesian Tropical Fruit Research Institute from July to Desember 2002. The objective of the study was to determine the best carrier for B. bassiana to control banana weevil borer, C. sordidus GERMAR. A randomized completely design with 7 treatments and 3 replications were used. Treatments consisted of 6 carriers, such as corn powder, talc, rice powder, maizena powder, Sania oil, water, and control (dry conidia). The results showed that rice powder was the best carrier for B. bassiana and caused highest mortality of banana corm borer. Whereas Sania oil carrier gave the lowest mortality of banana corm borer. The highest mortality of adult banana weevil borer, C. sordidus obtained when B. bassiana was exposed using rice powder carrier on pseudostem, which was 90%. While the B. bassiana exposed at liquid carrier of oil or water carrier on pseudostem, caused the lowest mortality of C. sordidus by 61 and 65%, respectively. The value of LT50 and LT95 from rice powder was lowest (12.93 days) and oil carrier was highest (23.34 days). The results demonstrated that powder as a carrier can enhance the efficacy of the insect pathogenic fungus B. bassiana against banana weevil borer, C. sordidus
