The field trial on the population dynamics of insect pests in okra during the Kharif season was conducted at the Organic Research Farm Karguaji, Department of Entomology, Institute of Agricultural Sciences, Bundelkhand University, Jhansi (Uttar Pradesh) during the Kharif season (July to October 2022). Based on the observations, the population results are as follows, the White fly, Bemisia tabaci (Genn.), started in the 28^th standard week (the second week of July) with an average of 1.83 white flies per plant and gradually increased, with a peak of 25.56 white flies per plant in the 37^th standard week (the second week of September). Jassid, Amrasca biguttula biguttula, began in the third week of July, the 29^th standard week, with an average of 1.45 jassids per plant and gradually increased, peaking at 11.09 jassids/plant during the 34^th standard week (the third week of August). Infestations of the red cotton bug, Dysdercus cingulatus, began in the 33rd standard week (the third week of August) and gradually increased peaking at 16.53 adults/plant in the 39^th standard week (the fourth week of September). Earias vitella, a shoot and fruit borer, was first observed in the 34^th standard week (the third week of August), with an average of 0.83 larvae per plant. And gradually increased and peaked at 5.92 larvae per plant during the 37^th standard week (September second week).
