Abstract

An experiment was carried out both in laboratory and field condition to evaluate the dose mortality response and bioefficacy of a new anthranilic diamide molecule, cyantraniliprole 10 OD against Leucinodes orbonalis a serious shoot and fruit borer pest of brinjal. Cyantraniliprole when applied as fruit dip, was 6543 times more toxic to L. orbonalis as compared to cypermethrin. The descending order of toxicity of tested insecticides was cyantraniliprole > chlorantraniliprole > flubendiamide > cypermethrin. Under laboratory bioassays the third instar larvae of L. orbonalis were found to be more susceptible to cyantraniliprole @ 90 g a.i./ha and recorded highest per cent mortality of 91.66 and 99.00 at 24 and 48 hrs after treatment. In field experiment, cyantraniliprole @ 105 g a.i. ha-1 was significantly most effective and recorded lowest per cent fruit damage of  8.92 and 8.25 with highest marketable fruit yield  of 18.46  and 22.40 t ha-1 during year 2010 and 2011, respectively. The present findings indicate that among different diamide insecticides, cyantraniliprole @ 90-105 g a.i. ha-1 proved to be highly effective against L. orbonalis. This novel molecule can be used as a new tool by farmers and new component for strengthening integrated pest management (IPM) and insecticide resistance management (IRM) programme for L. orbonalis.
