Abstract:
There are 26 insect-pests species and few non insect-pests species infesting brinjal of which the shoot and fruit borer, <em>Leucinodes orbonalis </em>(Guen.); Budworms, <em>Scrobipalpa blasigona; </em>whitefly, <em>Bemisia tabaci </em>(Genn.); leafhopper, <em>Amarasca devastans </em>(Distant); jassid, <em>A. biguttula biguttula</em> (Ishida) are major one. The brinjal shoot and fruit borer is considered the main constraint as it damages the crop throughout the year. The yield loss due to the pest is to the extent of 70-92 per cent. Among the various insecticides evaluated against brinjal shoot and fruit borer (<em>L. orbonalis</em>), Emamectin benzoate 5 SG @ 12.5g a.i./ha treated plots showed lowest infestation and gave higher fruit yield (253.12) followed by Flubendiamide 480 SC (249.33) and Novaluron 10 EC (243.63). The boipesticià·¬ NSKE 5% most effective followed by <em>Bacillus thuringensis,</em><em>Verticellium lecanii </em>and<em>Beauveria bassiana</em>. The highest cost: benefit ratio was obtained from NSKE 5% (1:24.40) followed by Indoxacarb 14.5 SC (1:24.13) and Emamectin benzoate 5 SG (1:24.03) which were also economical than other treatments.
