ABSTRACT
Sericulturists are facing problem with significant losses in mulberry leaf yield due to pests
infestation throughout the year. In order to control the pests infestation in mulberry, a research was
carried to explore the efficacy of copper oxide nanoparticles (CuO-NP) as nanopesticides in pest
management and ecofriendly alternatives to traditional pesticides. Synthesis of CuO-NPs was
achieved by Hydrothermal technique and confirmed through XRD, FTIR, DRS characterization.
CuO-NPs showed effective toxicity against Diaphania pulverulentalis with 100% larval mortality
at concentrations of 400 and 500mg/l in ultrapure water. While concentration of 300, 200 and
200mg/l observed 93.33%, 71.66% and 55% of larval mortality. Pupal mortality observed in 100-
500mg/l concentration of CuO-NPs as nanopesticides. The LC30, LC50, and LC90 values posttreatment
are 0.000, 0.002 and 0.0136 respectively. Statistical significance between pest mortality
and CuO-NPs concentration was observed at both the 16-hur and 24-hur time points. The study
revealed that, CuO-NPs act as pesticides against leaf roller and need further in-depth research on
its toxicity to other beneficial insects or non-targeted species.
