| description | Fall Armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae) is an important maize crop
pest that can cause farmers severe losses if not controlled. Biopesticide of entomopathogenic
fungi are an environmentally friendly alternative control measure that can reduce farmers’
dependence on chemical insecticides. Although there are several entomopathogenic fungi
based insecticides such as entomopathogenic fungi conidia, they have been found to have some
weaknesses. They are more stable in nature compared to synthetic insecticides and therefore
require a longer time to cause pest mortality, there is a need to formulate other alternatives with
the use of entomopathogenic fungi biopesticide culture filtrate. Therefore, this study aimed to
evaluate the potential of Bengkulu entomopathogenic fungus Nomuraea rileyi culture filtrate
isolate as a control agent against corn pest S. frugiperda. The bioactivity testing was carried
out by spraying the second instar larvae of S. frugiperda with N. rileyi culture filtrate at
concentrations (%): 1.0, 0.5, 0.75, 0.25, 0.125, 0.625, 0.05, 0.005 and control (sterile water).
Results showed that the N. rileyi culture filtrate was able to cause mortality of second instar S.
frugiperda larvae, with the mortality rate increasing with increasing culture filtrate
concentration (i.e. 0.625% - 1.0%). The highest mortality was recorded at a concentration of
1% reaching 100% on day 3, while at concentration of 0.05 and 0.005%, the mortality of S.
frugiperda larvae was under 10%. The culture filtrate of N. rileyi also caused mortality above
50% at concentrations of 0.50% and 0.75%. As such we suggest that the biological insecticide
developed from entomopathogenic fungi N. rileyi culture filtrate had the potential to be used
as an effective biological control agent (biolarvicide) against S. frugiferda. |
