Tobacco leaf eating caterpillar (Spodoptera litura F.) is a serious pest in tobacco nurseries and field crop. The pest causes damage to an extent of 80-100% in the nurseries under favourable wet conditions and 10-15% in the field crop. This pest is a limiting factor in the production of quality leaf. To manage this pest in the tobacco nurseries, an integrated pest management (IPM) system has been developed and tested under large scale field trials during the year 1993-94. The package consists of releasing Telenomus remus Nixon, an egg parasite, @ 40,000/ha three times at 3-week intervals, the first release commencing from three weeks after sowing of the tobacco nurseries, followed by release of Apanteles africanus C., a larval parasite, @ 3,500/ha three times at 3-week intervals, the first release commencing one week after first release of T. remus Nixon. Nuclear Polyhedrosis Virus was used @ 250 larval units/ha @ 2 sprays at 3-week interval commencing one week after the first release of A. africanus. A neem (Azadirachta indica A. Juss) seed kernel suspension 2% spray was carried out one week after the third release of A. africanus. Castor (Ricinus communis), an ovipositional trap crop for S. litura, was used as the female moths prefer to lay eggs on castor over tobacco. This helped in mass trapping of the egg masses and also in enhancing the parasitism in tobacco nurseries. The egg masses are collected every day in the morning and used for mass production of larvae which were in turn used for the production of Nuclear Polyhedrosis Virus in the laboratory. The cost benefit ratio of this IPM is 1:3.42 as against 1:1.68 in control (insecticidal spray). This method is eco-friendly and readily accepted by the tobacco farmers.
