| Experiment Background | Okra (Abelmoschus esculentus) also referred as lady’s finger is an important vegetable crop of the family Malvaceae. The place of origin is Ethiopia and is mainly grown for its green tender nutritive fruits. India is the largest producer of okra in the world. In India, it is grown on an area of 5.14 lakh hectare with an annual production of 61.26 lakh tons and productivity of 12 MT per hectare. West Bengal, Gujarat, Bihar, Odisha, Chhattisgarh, Jharkhand, Madhya Pradesh and Maharashtra are the major okra growing states in country. In India, more than 13 species of insect pests have been reported to infest okra crop (Mandal et al., 2007). (Mani and Singh 2012) reported 15 arthropod species in okra ecosystem. Among all, shoot and fruit borer (Earias sp.) is considered as the most important pest in okra (Aziz et al., 2011) which causes both quantitative and qualitative losses of the crop (Butani and Jotwani, 1984). The larvae bore into the terminal growing shoots, floral buds, flowers and fruits of okra, resulting in cessation, withering and drying of infested shoots, tender leaves and heavy shedding of floral buds and flowers. The infested fruits become malformed and are rendered unfit for human consumption as well as for procurement of the seeds. Grown up larva damages many fruits results in 54.04% yield loss and also reduces the vitality of the plant (Sivakumar et al., 2003). The borer has been reported to cause 24.6 to 26.0 percent damage to okra shoots (Pareek et al., 1986); Zala et al., 1999) and 40 to 100 per cent loss to fruits (Dhawan and Sidhu, 1984); (Kumawat, 1997); (Shah et al., 200); (Pareek and Bhargava, 2003); Shinde et al., 2007). Hence the present study will be carried out to evaluate the bio-efficacy of insecticides against okra shoot and fruit borer, Earias vittella Fabricius. | ||||||||||||||||||||||||||||||||
