Abstract:

A field experiment was conducted during the Kharif seasons 2012 and 2013 at Students Instructional Farm and Vegetable Research Farm, NDUA&T, Kumarganj, Faizabad (UP) to find out the natural enemies of shoot and fruit borer in okra. The eggs parasitoids Trichogramma chilonis, parasitized 6.25 and 7.40% egg of Earias spp Kharif, 2012 and Kharif, 2012 respectively. Among predators, maximum population of Coccinellids 4.36 and 4.05 adult per 5 plants was recorded in third week of August. The maximum population of spiders 6.40 and 6.22 individuals per 5 plant were in the last week of July, Ants population were 4.38 and 4.22 in the mid July of and Mirid bug ranged from 1.42 to 3.88 and 1.08 to 3.56 adult/ 5plant. The population of Coccinellids, spiders, ants and mirid bugs were positive correlated with minimum temperature i.e. (0.921, 0.809, 0.777 and 0.810) and (0.595, 0.407, 0.347 and 0.399) respectively during Kharif, 2012 and 2013.
