Description 224-229
Major loss in agricultural crops is caused by insect pests. In India,
various synthetic insecticides are used against pests. These are much
expensive and cause environmental hazards. The nanoparticles, as an
alternative approach is gaining considerable interest in this field. In the
present study, we explored the biological synthesis of zinc oxide
nanoparticles using Giant milkweed, Calotropis procera (Aiton)
Dryand. and its effects on the tobacco cutworm, Spodoptera litura. The
reduction of zinc ions (Zn2+) to zinc nanoparticles (ZnO NPs) was
prepared by mixing 50 g of C. procera leaves with 100 mL of single
distilled water in a 250 mL glass beaker. To synthesize nanoparticles,
50 mL of C. procera leaf extract was taken using a stirrer-heater and 5 g
of zinc oxide was added at 60ºC, boiled, then kept in a hot air oven at
70ºC for 24 h. Finally, the obtained light yellow coloured powder was
carefully collected and characterized using X-ray diffraction (XRD)
analysis. The results revealed that the biologically synthesized zinc
oxide nanoparticles pesticide was highly effective against the pest. The
weight of the pest decreased from low concentration to high
concentration. It is concluded that the Calotropis Procera based zinc
oxide nanoparticles could be used for the control of Spodoptera litura.
