EFFECTIVENESS TEST OF ENTOMOPATOGEN FUEL Metarhizium anisopliae (Metch) IN VARIOUS CONCENTRATIONS OF GRAYWRATER Spodoptera frugiperda J. E. Smith (Lepidoptera: Noctuidae) IN LABORATORIUM Departement of plant pest and diseases, Faculty of Agriculture, Abstract Spodoptera frugiperda is one of the most important major pests of maize in the world. FAW is a migratory and polyphagous pest that can attack 353 host plant species from 76 plant families. Armyworm caterpillars are polyphagous, their main target is corn, pests can move to other hosts if there is no primary host so that these pests can survive and maintain their populations throughout the year. S.frugiperda is also considered a serious insect pest because it reproduces in several generations per year and adults can fly up to 100 km per night, giving it the potential to spread widely in a short time. This study aims to determine the effectiveness of the entomopagen fungus Metarhizium anisopliae (metch) at various concentrations against S. Frugiperda armyworm. This study was conducted in laboratory conditions, using a completely randomized design using four treatments and five replications. Each replicate used 20 test larvae. the treatments were: Control, Concentration of M. anisopliae 107, Concentration of M. anisopliae 108 , Concentration of M. anisopliae 109. The larvae used as test larvae were instar 2 larvae, observations were made every day to see the mortality of the test insects and record the symptoms appeared in larvae after application of M. anisopliae. The results showed that there was an effect of mortality on the test insects seen in treatment 108 showing the highest treatment of 9.15% compared to all treatments. at 14 days post application. The results of this study indicate the need for proper development for the purpose of effective pest control in crop cultivation. Keywords: Metarhizium anisopliae, Mortality.
