Cotton is a major fiber crop and used for textile purpose by about 75 percent of worldÃ¢â‚¬â„¢s population .Cotton plays a key role in the National economy in terms of direct and indirect employment and income generation in the agricultural and industrial sectors. Textiles and related exports of which cotton alone comprised nearly 65 per cent and accounts for nearly 33 per cent of the total foreign exchange earnings of our country which at present is around 12 billion dollars. In India, Bt cotton since its release in 2002 by Genetic Engineering Approval Committee replaced more and more conventional cotton area. There was an exponential increase in Bt cotton area accounting for a staggering 92 per cent of the total cotton area in India. The production increased 31.20 million bales during 2010- 11 (Anon., 2014). In Haryana cotton is grown during Kharif season. Cotton accounts for an area of 610 thousand ha in Haryana with total production of 24,000 thousand bales and yield of lint is 664.50 kg / ha (Anonymous 2014). Cotton is attacked by several insect pests reducing the crop yield to a greater extent. The insect pests that attack cotton crop may be classified into sap sucking insects (aphids, Jassids and white fly) or chewing insects (bollworms, leaf eating caterpillars etc.) of the total pesticides used in Indian Agriculture, about 45 per cent is sprayed on cotton crop alone. To reduce pesticide usage in cotton, several strategies like use of Genetic Resistance to insect pests, Integrated Pest Management (IPM), Insecticide Resistance Management (IRM) etc. are advocated. In recent times, Bt cotton technology is found to be one of the best strategies to manage bollworms, the most important pest of cotton. The present study was conducted during 2014-2015 in Haryana. Two districts Hisar and Sirsa were purposely selected for the study because they have largest area of production under Bt cotton. The present study was conducted in purposely selected districts of Hisar and Sirsa of the native state Haryana.
