Abstract:
The use of organosynthetic pesticides in pest management results in a number of issues that includes the loss of natural enemy populations and development of the resistance in the pest. To overcome this issue in pest management specific pesticides or biopesticides are generally recommended. In this study, we isolated nimbolide, a tetranortriterpenoid biomolecule from Azadirachta indica leaves and tested in vitro for its insecticidal efficacy against Spodoptera frugiperda. Insecticidal activity exerted by nimbolide and neem leaf extract was experimented in dose dependent manner and the results indicated that the maximum mortality of 93.33 and 90.00 per cent was observed at 10000 ppm on sixth day of treatment with nimbolide and neem leaf extract. Nimbolide also causes growth abnormalities in larvae as well as prolonging their growth when compared with the neem leaf extract. The present study clearly indicated nimbolide has insecticidal activity and it can be utilized for the development of nimbolide-based biopesticides.
