| Summary: | German cockroaches have been reported to have developed resistance to 42 active insecticide ingredients. An effort to minimize the development of resistance in German cockroaches is to use organic insecticides, one of which is a secondary metabolite from the entomopathogenic fungus Beauveria bassiana (B10). The purpose of this study was to determine the susceptibility of German cockroaches to the organic insecticide B10, which contains secondary metabolites of B. bassiana. This study used an experimental method with a completely randomized design consisting of ten treatments, namely concentrations of 0, 0.1, 0.5, 1, 5, 10, 20, 30, 40, and 50% (v / w). Each treatment unit used ten male German cockroaches which were repeated three times. Mortality data were analyzed using ANOVA followed by Duncan's test at a significance level of p <0.05. The results showed that the application of organic insecticide B. bassiana B10 was quite effective in controlling German cockroaches as indicated by the mortality of German cockroaches. The application of B. bassiana B10 secondary metabolites causing the mortality of German cockroaches with a concentration of 40 % with a mortality percentage of 50%. |
