Green house experiment was conducted during rabi, 2010-11 at College of Agriculture, Rajendranagar, Hyderabad
to evaluate efficacy of different insecticides against Sesamia inferens Walker with susceptible single cross hybrid,
DHM 117 where each plant was infested with 10 larvae. There were five treatments including endosulfan,
carbofuran, Beauveria bassiana Balsamo and Bacillus thuringiensis Berliner and untreated control. Data was
recorded on leaf injury rating (LIR) at 40 days after germination (DAG) and on percent dead hearts, stem tunneling,
number of live larvae recovered, % larval mortality and number of exit holes at 14 and 28 DAG. Among the
treatments, endosulfan was found to be more effective with 4.55 leaf injury rating, 26.25 per cent dead hearts, 0.33
cm per metre stem tunneling, 0.45 exit holes per plant, and 41.66 percentage of live larval recovery followed by
carbofuran, B. bassiana and B. thuringiensis.
