Sixteen okra genotypes viz., 326- 10-1, 633-7-1, IC – 140206, IC – 282280, 303- 10- 1, 461-10-1, IC- 43742, 419-10-1, 599-8-1, IPM-20- 16-39, 1753, IC- 288892, 304-10-1, 100-10-1, 231- 10-1 and VRO-22 were screened to know their response on the basis of fruit damage scale. Only two genotypes viz., IC – 282280 and 303- 10- 1 showed tolerant, remained genotypes were falled in the category of moderately resistance, However, the IPM-20- 16-39 showed minimum fruit damage with highest yield 32.29 q/ha, while, IC – 282280 genotype showed highest no. of fruit damage and fruit weight damage and it exhibited lowest health fruit yield 16.77 q/ha was noticed during 2015-16 and 2016-17. The peak borer infestation (24.50%) was recorded during fourth week of September. Keywords: Okra, Earias vittella, varieties, infestation, genotypesn Introduction Okra (Abelmoschus esculentus (L.) Moench) or Bhindi or lady’s finger is an important Malvaceaous vegetable crop grown in India. Vegetables constitute an important item of our food, supplying vitamins, carbohydrates and minerals needed for a balanced diet. Their value is important especially in under developed and developing countries like India. Among the states, West Bengal is the leading okra producing state which has production of around 718.9 thousand tonnes followed by Bihar (714.1 thousand tonnes) and Orissa (618.8 thousand tonnes). It is grown mostly in Hoogly, Mursidabad, Nadia, 24 Parganas, Bankur and Midnapur districts. Okra is attacked by a number of insect pests, of which shoot and fruit borer, Earias spp. is one of the major constraints in achieving potential yield. It is commonly known as many names in different countries as Bhindi in India, Krajiab Kheaw in Thailand, kopi in arab, Bhindi in South East Asia, Asbamia, Bamya or Bamieh and gumbo in Southern, quiabo in Portuguese and Angola, Quimbombo in Cuba, gombo commun, gombo, gumbo in France, mbamia and Mbinda in Sweden, and in Japan as okura, qiu kui in Taiwan and Igbo in Nigeria. It is a polyploidy, belong to family Malvaceae with 2n = 8x = 72,144 chromosome, it is an often cross pollinated crop, occurrence of out crossing to an extent of 4-19 per cent with the maximum of 42.2 per cent is noticed with insect assisted pollination The infested fruits become unfit for human consumption, thus resulting in 35 to 76 % decrease in yield (Hafeez and Rizvi, 1994) [3] and caused severe damage to the crop leading to yield losses to an extent of 3.5-90% in Andhra Pradesh (Krishnaiah et al., 1976) [7] and 30.81% at Coochbehar, West Bengal (Ghosh et al., 1999). Application of pesticides as the plant protection measures to overcome the pest problem causes the pesticide residues problem in harvested product and hazardous to consumers. Considering the limitations of chemical control, use of natural plant resistance to their pest at- tack can overcome the problem. Keeping this in view, the present studies were undertaken to screen out some okra varieties/cultivars against okra shoot and fruit borer. Materials and Methods The field experiment were conducted at entomology research farm, RVSKVV, Gwalior, Madhya Pradesh during kharif season 2015-16 and 2016-17 taken to know the infestation of
