The present study was conducted at Horticultural Research Farm, College of Agriculture, Indira Gandhi KrishiVishwavidyalaya; Raipur (C.G.) during kharif season 2015-16. The results of field experiments revealed that the major insect pest viz., spotted pod borer, flower thrips, pod sucking bug and green stink bug were attacking in cowpea germplasm Lola. The incidence of pod sucking bug, green stink bug and flower thrips started from third week after transplanting, further increased and recorded the peak activity of 9.0 bugs per plant and 12.3 bugs per plant during second week of November, whereas the peak activity of 4.3 thrips per plant was observed during first week of October. The cowpea spotted pod borer infestation was first appeared during fifth week of September, increased gradually with peak pod infestation of 19.7 per cent during third week of October. The population of flower thrips and pod sucking bug was positively and non significant correlated with maximum and minimum temperature while negatively correlated with maximum and minimum relative humidity, rainfall and sunshine hours. The cowpea spotted pod borer infestation showed positive and non significant correlation with maximum and minimum temperature, rainfall, sunshine hours, maximum and minimum relative humidity.
