HISTORICAL MILESTONE Acharya N. G. Ranga Agricultural University (ANGRAU) was established under the name of Andhra Pradesh Agricultural University (APAU) on the 12th of June 1964 through the APAU Act 1963.

    INFLUENCE OF DIATOMACEOUS EARTH IN COMBINATION WITH SPINOSAD TO CONTROL Sitophilus oryzae (Linn.) AND Rhyzopertha dominica (Fab.)”
    (Acharya N.G. Ranga Agricultural University, 2016) ANILKUMAR YADAV, KRISTAM; MADHUMATHI, T
    The present investigation entitled ‘Influence of diatomaceous earth in combination with spinosad to control Sitophilus oryzae L. and Rhyzopertha dominica F.’ was conducted in the Department of Entomology, Agricultural College, Bapatla, Guntur district, Andhra Pradesh during 2013-14. The efficacy and persistence of DE alone and in combination with spinosad by mixing with grain, as surface application treatment on jute cloth disc and usage with different packing materials was studied under the laboratory conditions. Maize kernels were used against S. oryzae and wheat grains were used against R. dominica for grain treatment experiments. The mortality of S. oryzae and R. dominica in DE alone and spinosad alone treatments decreased over 150 DAT and the combination treatments enhanced the mortality rates of both the test insects S. oryzae and R. dominica compared with DE alone or spinosad alone treatments. At 150 DAT by 14 DAR the highest cumulative mortality (100.00 %) of S. oryzae was observed in the DE in combination with spinosad treatments viz., DE + spinosad @ 750 mg/kg + 1.0 mg/kg and @ 1000 mg/kg + 1.0 mg/kg. whereas in case of R. dominica all the four combination treatments of DE and spinosad viz., DE + spinosad @ 750 mg/kg + 0.5 mg/kg, @ 750 mg/kg + 1.0 mg/kg, @ 1000 mg/kg + 0.5 mg/kg and @ 1000 mg/kg + 1.0 mg/kg gave cent per cent mortality even at 150 DAT by 14 DAR. All the DE alone and spinosad alone treatments showed decreased efficacy by 150 DAT against both the test insects (S. oryzae and R. dominica) on both the commodities (maize kernels and wheat grains). DE and spinosad in combination were also found to be excellent as surface application on jute cloth disc against the test insects, S. oryzae and R. dominica. The combination treatments enhanced the percentage mortality of the test insects, S. oryzae and R. dominica. R. dominica was found to be more susceptible to spinosad than S. oryzae on the treated jute cloth disc. All the combination treatments of DE and spinosad as surface application on jute cloth disc viz., DE + spinosad @ 1.0 mg/cm2 + 0.05 mg/cm2, @ 1.0 mg/cm2 + 0.03 mg/cm2, @ 0.75 mg/cm2 + 0.05 mg/cm2 and @ 0.75 mg/cm2 + 0.03 mg/cm2, recorded cent per cent mortality of R. dominica by 72 HAR even at 150 DAT. However among these combination treatments the treatment DE + spinosad @ 0.75 mg/cm2 + 0.03 mg/cm2 could not record cent per cent mortality by 72 HAR at 150 DAT. Among different packing materials filled with untreated maize kernels and wheat grains super bag was found to be best which recorded highest per cent of cumulative mortality of S. oryzae and R. dominica, this was followed by magik bag. The jute bag alone was found to be the least effective. In the treatments with different packing materials filled with maize kernels and wheat grains treated with DE and spinosad in combination @ 1000 mg/kg + 1.0 mg/kg, again the super bag with the combination of DE and spinosad was found superior over other bags (magik and jute bags) with treated grain in them. The jute bag surface treated with DE and spinosad @ 1.0 mg/cm2 + 0.05 mg/cm2 showed decreased in its efficacy by 150 DAT in case of both S. oryzae and R. dominica against maize kernels and wheat grains respectively.
